-
-This reference document lists the requirements that are the supporting
-details for the Virtual Network Function (VNF) characteristics outlined
-in the *VNF Guidelines for Network Cloud and OpenECOMP*. These
-requirements are grouped into the following categories: VNF Design,
-Resiliency, Security, and DevOps. Specific requirements for OpenECOMP
-can be found in the *VNF Management Requirements for OpenECOMP*
-reference document.
-
-This section outlines the guidelines for VNFs to be compliant with
-running on a multi-tenant, Network Cloud infrastructure. VNFs must be
-virtualized, software-based, execute in a multi-tenant cloud, and be
-de-coupled from the cloud hardware. To achieve interoperability between
-VNFs, open and standard interfaces and APIs must be used. The set of
-reusable VNFs forms the basis of a VNF catalog that is made available to
-service designers to compose new (service chained) services that can
-include service-specific custom parameters and QoS policies. Use of open
-source technologies to leverage industry innovation is important in the
-design of virtualized services. Equally important is the re-use of
-common technologies (e.g., virtualized load balancers, firewalls, etc.)
-that are provided by the platform.
-
-VNF Design
-==========
-
-Services are composed of VNFs and common components and are designed to
-be agnostic of the location to leverage capacity where it exists in the
-Network Cloud. VNFs can be instantiated in any location that meets the
-performance and latency requirements of the service.
-
-A key design principle for virtualizing services is decomposition of
-network functions using NFV concepts into granular VNFs. This enables
-instantiating and customizing only essential functions as needed for the
-service, thereby making service delivery more nimble. It provides
-flexibility of sizing and scaling and also provides flexibility with
-packaging and deploying VNFs as needed for the service. It enables
-grouping functions in a common cloud data center to minimize
-inter-component latency. The VNFs should be designed with a goal of
-being modular and reusable to enable using best-in-breed vendors
-
-Section 4.1.1 in *VNF Guidelines for Network Cloud and OpenECOMP*
-describes the overall guidelines for designing VNFs from VNF Components
-(VNFCs). Below are more detailed requirements for composing VNFs.

-+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Decomposition of the VNF must enable instantiating only the functionality that is needed for the VNF (e.g., if transcoding is not needed it should not be instantiated). | Must | 20030 |

-+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-
-Resiliency
-==========
-
-The VNF is responsible for meeting its resiliency goals and must factor
-in expected availability of the targeted virtualization environment.
-This is likely to be much lower than found in a traditional data center.
-Resiliency is defined as the ability of the VNF to respond to error
-conditions and continue to provide the service intended. A number of
-software resiliency dimensions have been identified as areas that should
-be addressed to increase resiliency. As VNFs are deployed into the
-Network Cloud, resiliency must be designed into the VNF software to
-provide high availability versus relying on the Network Cloud to achieve
-that end.
-
-Section 4.1.2 in *VNF Guidelines for Network Cloud and OpenECOMP*
-describes the overall guidelines for designing VNFs to meet resiliency
-goals. Below are more detailed resiliency requirements for VNFs.
-
-All Layer Redundancy
---------------------
-
-Design the VNF to be resilient to the failures of the underlying
-virtualized infrastructure (Network Cloud). VNF design considerations
-would include techniques such as multiple vLANs, multiple local and
-geographic instances, multiple local and geographic data replication,
-and virtualized services such as Load Balancers.
-
-+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| All Layer Redundancy Requirements | Type | ID # |
-+=====================================================================================================================================================================================================================+========+=========+
-| VNFs are responsible to meet their own resiliency goals and not rely on the Network Cloud. | Must | 30010 |
-+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Design resiliency into a VNF such that the resiliency deployment model (e.g., active-active) can be chosen at run-time. | Must | 30020 |
-+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| VNFs must survive any single points of failure within the Network Cloud (e.g., virtual NIC, VM, disk failure). | Must | 30030 |
-+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| VNFs must survive any single points of software failure internal to the VNF (e.g., in memory structures, JMS message queues). | Must | 30040 |
-+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Design, build and package VNFs to enable deployment across multiple fault zones (e.g., VNFCs deployed in different servers, racks, OpenStack regions, geographies) to increase the overall resiliency of the VNF. | Must | 30050 |
-+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Support the ability to failover a VNFC automatically to other geographically redundant sites if not deployed active-active to increase the overall resiliency of the VNF. | Must | 30060 |
-+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Support the ability of the VNFC to be deployable in multi-zoned cloud sites to allow for site support in the event of cloud zone failure or upgrades. | Must | 30070 |
-+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-
-Minimize Cross Data-Center Traffic
-----------------------------------
-
-Avoid performance-sapping data center-to-data center replication delay
-by applying techniques such as caching and persistent transaction paths
-- Eliminate replication delay impact between data centers by using a
-concept of stickiness (i.e., once a client is routed to data center "A",
-the client will stay with Data center “A” until the entire session is
-completed).
-
-+------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Minimize Cross Data-Center Traffic Requirements | Type | ID # |
-+==================================================================================================================+==========+=========+
-| Minimize the propagation of state information across multiple data centers to avoid cross data center traffic. | Should | 31010 |
-+------------------------------------------------------------------------------------------------------------------+----------+---------+
-
-Application Resilient Error Handling
-------------------------------------
-
-Ensure an application communicating with a downstream peer is equipped
-to intelligently handle all error conditions. Make sure code can handle
-exceptions seamlessly - implement smart retry logic and implement
-multi-point entry (multiple data centers) for back-end system
-applications.
-
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Application Resilient Error Handling Requirements | Type | ID # |
-+==============================================================================================================================================================================================================================================================================================================================+========+=========+
-| Detect connectivity failure for inter VNFC instance and intra/inter VNF and re-establish connectivity automatically to maintain the VNF without manual intervention to provide service continuity. | Must | 32010 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Handle the restart of a single VNFC instance without requiring all VNFC instances to be restarted. | Must | 32020 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Handle the start or restart of VNFC instances in any order with each VNFC instance establishing or re-establishing required connections or relationships with other VNFC instances and/or VNFs required to perform the VNF function/role without requiring VNFC instance(s) to be started/restarted in a particular order. | Must | 32030 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Handle errors and exceptions so that they do not interrupt processing of incoming VNF requests to maintain service continuity. | Must | 32040 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Provide the ability to modify the number of retries, the time between retries and the behavior/action taken after the retries have been exhausted for exception handling to allow the Network Cloud Service Provider to control that behavior. | Must | 32050 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Fully exploit exception handling to the extent that resources (e.g., threads and memory) are released when no longer needed regardless of programming language. | Must | 32060 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Handle replication race conditions both locally and geo-located in the event of a data base instance failure to maintain service continuity. | Must | 32070 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Automatically retry/resubmit failed requests made by the software to its downstream system to increase the success rate. | Must | 32080 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-
-System Resource Optimization
-----------------------------
-
-Ensure an application is using appropriate system resources for the task
-at hand; for example, do not use network or IO operations inside
-critical sections, which could end up blocking other threads or
-processes or eating memory if they are unable to complete. Critical
-sections should only contain memory operation, and should not contain
-any network or IO operation.
-
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| System Resource Optimization Requirements | Type | ID # |
-+=================================================================================================================================================================================================================================================+==========+=========+
-| Do not execute long running tasks (e.g., IO, database, network operations, service calls) in a critical section of code, so as to minimize blocking of other operations and increase concurrent throughput. | Must | 33010 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Automatically advertise newly scaled components so there is no manual intervention required. | Must | 33020 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Utilize FQDNs (and not IP address) for both Service Chaining and scaling. | Must | 33030 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Deliver any and all functionality from any VNFC in the pool. The VNFC pool member should be transparent to the client. Upstream and downstream clients should only recognize the function being performed, not the member performing it. | Must | 33040 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Automatically enable/disable added/removed sub-components or component so there is no manual intervention required. | Should | 33050 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Support the ability to scale down a VNFC pool without jeopardizing active sessions. Ideally, an active session should not be tied to any particular VNFC instance. | Should | 33060 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+

-Security
-========
-
-The objective of this section is to provide the key security
-requirements that need to be met by VNFs. The security requirements are
-grouped into five areas as listed below. Other security areas will be
-addressed in future updates. These security requirements are applicable
-to all VNFs. Additional security requirements for specific types of VNFs
-will be applicable and are outside the scope of these general
-requirements.
-
-Section 4.1.3 in *VNF Guidelines for Network Cloud and OpenECOMP*
-outlines the five broad security areas for VNFs that are detailed in the
-following sections:
-
-- **VNF General Security**: This section addresses general security
- requirements for the VNFs that the vendors will need to address.
-
-- **VNF Identity and Access Management**: This section addresses
- security requirements with respect to Identity and Access Management
- as these pertain to generic VNFs.
-
-- **VNF API Security**: This section addresses the generic security
- requirements associated with APIs. These requirements are applicable
- to those VNFs that use standard APIs for communication and data
- exchange.
-
-- **VNF Security Analytics**: This section addresses the security
- requirements associated with analytics for VNFs that deal with
- monitoring, data collection and analysis.
-
-- **VNF Data Protection**: This section addresses the security
- requirements associated with data protection.

-Abstract
-========
-
-This white paper and the accompanying reference documents set forth
-guidelines and requirements for Virtual Network Functions (VNFs) that
-run in Network Clouds [1]_ and are managed by OpenECOMP [2]_. This
-document set is part of the OpenECOMP community and focuses on setting
-and evolving VNF standards that will facilitate industry discussion,
-participation, alignment and evolution toward comprehensive and
-actionable VNF best practices and standard interfaces. The goal is to
-accelerate adoption of VNF best practices which will increase
-innovation, minimize customization needed to onboard VNFs as well as
-reduce implementation complexity, time and cost for all impacted
-stakeholders. The intent is to drive harmonization of VNFs across VNF
-providers, Network Cloud Service Providers (NCSPs) and the overall
-Network Function Virtualization (NFV) ecosystem by providing both long
-term vision as well as short term focus and clarity where no current
-open source implementations exist today.
-
-This first release of the guidelines and requirements, although
-applicable in many implementations, is targeted for those
-implementations that consist of Network Clouds based on OpenStack.
-Future versions of these guidelines are envisioned to include other
-targeted virtualization environments, such as Customer Premises or other
-single-tenant small scale cloud implementations.
-
-In addition, given the relative maturity of key technologies involved,
-rapid innovation of NFV/SDN and virtualization technologies as well as
-the evolving OpenECOMP roadmap, this will be a living package that will
-evolve over time. These documents will become part of the OpenECOMP
-related requirements documents. The following enhancements are
-anticipated to be addressed in the next set of releases:
-
-- Open source software and demos of simple reference VNFs;
-
-- Automation of VNF onboarding and other aspects of VNF lifecycle as
- supported by OpenECOMP;
-
-- Consistent VNF packaging for automated onboarding using OpenECOMP;
-
-- Other implementation examples for targeted virtualization
- environments beyond OpenStack based Network Clouds;
-
-- Incubation and certification environment to provide a self-service
- program to gauge maturity and readiness of VNFs.
-
-Introduction
-============
-
-Motivation
-----------
-
-The requirements and guidelines defined herein are intended to
-facilitate industry discussion, participation alignment and evolution
-toward comprehensive and actionable VNF best practices. Integration
-costs are a significant impediment to the development and deployment of
-new services. We envision developing open source industry processes and
-best practices leading eventually to VNF standards supporting commercial
-acquisition of VNFs with minimal integration costs. Traditional PNFs
-have all been unique like snowflakes and required expensive custom
-integration, whereas VNF products and services should be designed for
-easier integration just like Lego\ :sup:`TM` blocks. For example, by
-standardizing on common actions and related APIs supported by VNFs, plug
-and play integration is assured, jumpstarting automation with management
-frameworks. Onboarding VNFs would no longer require complex and
-protracted integration or development activities thus maximizing
-automation and minimizing integration cost. Creating VNF open source
-environments, best practices and standards provides additional benefits
-to the NFV ecosystems such as:
-
-- Larger market for VNF providers
-
-- Rapid introduction and integration of new capabilities into the
- services providers environment
-
-- Reduced development times and costs for VNF providers
-
-- Better availability of new capabilities to NCSPs
-
-- Better distribution of new capabilities to end-user consumers
-
-- Reduced integration cost (capex) for NCSPs
-
-- Usage based software licensing for end-user consumers and NCSPs
-
-Audience
----------
-
-The industry transformation associated with softwarization [3]_ results
-in a number of changes in traditional approaches for industry
-collaboration. Changes from hardware to software, from waterfall to
-agile processes and the emergence of industry supported open source
-communities imply corresponding changes in processes at many industry
-collaboration bodies. With limited operational experience and much more
-dynamic requirements, open source communities are expected to evolve
-these VNF guidelines further before final documentation of those aspects
-necessary for standardization. This white paper and accompanying
-reference documents provides VNF providers, NCSPs and other interested
-3rd parties a set of guidelines and requirements for the design, build
-and overall lifecycle management of VNFs.
-
-**VNF Providers**
-
-Both suppliers transitioning from providing physical network functions
-(PNFs) to providing VNFs as well as new market entrants should find
-these VNF requirements and guidelines a useful introduction to the
-requirements to be able to develop VNFs for deployment into a Network
-Cloud. VNF Providers may also be interested to test their VNFs in the
-context of an open source implementation of the environment.
-
-**Network Cloud Service Providers (NCSPs)**
-
-A NCSP provides services based on Network Cloud infrastructure as well
-as services above the infrastructure layer, e.g., platform service,
-end-to-end services.
-
-Common approaches to packaging of VNFs enable economies of scale in
-their development. As suitable infrastructure becomes deployed, NCSPs
-have a common interest in guidelines that support the ease of deployment
-of VNFs in each other’s Network Cloud. After reading these VNF
-guidelines, NCSPs should be motivated to join AT&T in evolving these
-guidelines in the OpenECOMP open source community to meet the industry’s
-collective needs.
-
-**Other interested parties**
-
-Other parties such as solution providers, open source community,
-industry standard bodies, students and researchers of network
-technologies, as well as enterprise customers may also be interested in
-the VNF Guidelines. Solution Providers focused on specific industry
-verticals may find these VNF guidelines useful in the development of
-specialized VNFs that can better address the needs of their industry
-through deployment of these VNFs in NCSP infrastructure. Open Source
-developers can use these VNF guidelines to facilitate the automation of
-VNF ingestion and deployment. The emergence of a market for VNFs enables
-NCSPs to more rapidly deliver increased functionality, for execution on
-white box hardware on customer’s premises – such functionality may be of
-particular interest to enterprises supporting similar infrastructure.

-
-VNF Context
-===========
-
-A technology trend towards softwarization is impacting the
-communications industry as it has already impacted a number of other
-industries. This trend is expected to have some significant impacts on
-the products and processes of this industry. The transformation from
-products primarily based on hardware to products primarily based on
-software has a number of impacts. The completeness of the software
-packages to ease integration, usage based licensing to reflect scaling
-properties, independence from hardware and location and software
-resilience in the presence of underlying hardware failure all gain in
-importance compared to prior solutions. The processes supporting
-software products and services are also expected to transform from
-traditional waterfall methodologies to agile methods. In agile
-processes, characteristics such as versioned APIs, rolling upgrades,
-automated testing and deployment support with incremental release
-schedules become important for these software products and services.
-Industry process related to software products and services also change
-with the rise of industrially supported open source communities.
-Engagement with these open source communities enables sharing of best
-practices and collaborative development of open source testing and
-integration regimes, open source APIs and open source code bases.
-
-The term VNF is inspired by the work [4]_ of the ETSI [5]_ Network
-Functions Virtualization (NFV) Industry Specification Group (ISG).
-ETSI’s VNF definition includes both historically network functions, such
-as Virtual Provider Edge (VPE), Virtual Customer Edge (VCE), and Session
-Border Controller (SBC), as well as historically non-network functions
-when used to support network services, such as network-supporting web
-servers and databases. The VNF discussion in these guidelines applies to
-all types of virtualized workloads, not just network appliance
-workloads. Having a consistent approach to virtualizing any workload
-provides more industry value than just virtualizing some workloads. [6]_
-
-VNFs are functions that are implemented in Network Clouds. Network
-Clouds must support end-to-end high-bandwidth low latency network flows
-through VNFs running in virtualization environments. For example, a
-Network Cloud is able to provide a firewall service to be created such
-that all Internet traffic to a customer premise passes through a virtual
-firewall running in the Network Cloud.
-
-A data center may be the most common target for a virtualization
-environment, but it is not the only target. Virtualization environments
-are also supported by more constrained resources e.g., Enterprise
-Customer Premise Equipment (CPE). Virtualization environments are also
-expected to be available at more distributed network locations by
-architecting central offices as data centers, or virtualizing functions
-located at the edge of the operator infrastructure (e.g., virtualized
-Optical Line Termination (vOLT) or xRAN [7]_) and in constrained
-resource Access Nodes. Expect detailed requirements to evolve with these
-additional virtualization environments. Some VNFs may scale across all
-these environments, but all VNFs should onboard through the same process
-before deployment to the targeted virtualization environment.
-
-Business Process Impacts
--------------------------
-
-Business process changes need to occur in order to realize full benefits
-of VNF characteristics: efficiency via automation, open source reliance,
-and improved cycle time through careful design.
-
-**Efficiency via Automation**
-
-reliant on human labor for critical operational tasks don’t scale. By
-aggressively automating all VNF operational procedures, VNFs have lower
-operational cost, are more rapidly deployed at scale and are more
-consistent in their operation. OpenECOMP provides the automation
-framework which VNFs can take advantage of simply by implementing
-OpenECOMP compatible interfaces and lifecycle models. This enables
-automation which drives operational efficiencies and delivers the
-corresponding benefits.
-
-**Open Source**
-
-VNFs are expected to run on infrastructure largely enabled by open
-source software. For example, OpenStack [8]_ is often used to provide
-the virtualized compute, network, and storage capabilities used to host
-VNFs. OpenDaylight (ODL) [9]_ can provide the network control plane. The
-OPNFV community [10]_ provides a reference platform through integration
-of ODL, OpenStack and other relevant open source projects. VNFs also run
-in open source operating systems like Linux. VNFs might also utilize
-open source software libraries to take advantage of required common but
-critical software capabilities where community support is available.
-Automation becomes easier, overall costs go down and time to market can
-decrease when VNFs can be developed and tested in an open source
-reference platform environment prior to on-boarding by the NCSP. All of
-these points contribute to a lower cost structure for both VNF providers
-and NCSPs.
-
-**Improved Cycle Time through Careful Design**
-
-Today’s fast paced world requires businesses to evolve rapidly in order
-to stay relevant and competitive. To a large degree VNFs, when used with
-the same control, orchestration, management and policy framework (e.g.,
-OpenECOMP), will improve service development and composition. VNFs
-should enable NCSPs to exploit recursive nesting of VNFs to acquire VNFs
-at the smallest appropriate granularity so that new VNFs and network
-services can be composed. The ETSI NFV Framework [11]_ envisages such
-recursive assembly of VNFs, but many current implementations fail to
-support such features. Designing for VNF reuse often requires that
-traditional appliance based PNFs be refactored into multiple individual
-VNFs where each does one thing particularly well. While the original
-appliance based PNF can be replicated virtually by the right combination
-and organization of lower level VNFs, the real advantage comes in
-creating new services composed of different combinations of lower level
-VNFs (possibly from many providers) organized in new ways. Easier and
-faster service creation often generates real value for businesses. As
-softwarization trends progress towards more agile processes, VNFs,
-OpenECOMP and Network Clouds are all expected to evolve towards
-continuous integration, testing and deployment of small incremental
-changes to de-risk the upgrade process.
-
-ETSI Network Function Virtualization (NFV) comparison
------------------------------------------------------
-
-ETSI defines a VNF as an implementation of a network function that can
-be deployed on a Network Function Virtualization Infrastructure (NFVI).
-Service instances may be composed of an assembly of VNFs. In turn, a VNF
-may also be assembled from VNF components (VNFCs) that each provide a
-reusable set of functionality. VNFs are expected to take advantage of
-platform provided common services.
-
-VNF management and control under OpenECOMP is different than management
-and control exposed in the ETSI MANO model. With OpenECOMP, there is
-only a single management and control plane. In ETSI’s Framework [12]_,
-architectural options exist for preserving legacy systems that increase
-integration costs e.g., different VNFs can be controlled by VNF Managers
-(VNFMs) and Element Management Systems (EMSs) provided by different
-software providers. OpenECOMP addresses the concern that multiple VNFMs
-in this space will hinder VNF reuse and increase VNF and service
-integration costs. Asking all VNF providers to take advantage of and
-interoperate with common control software mitigates related reuse and
-integration challenges. The common, SDN based, control platform
-(OpenECOMP) is being made available as an open source project to reduce
-friction for VNF providers and enable new network functions to get to
-market faster and with lower costs.
-
-Also under OpenECOMP, VNF providers do not provide their own proprietary
-VNF Managers (VNFM) or Element Management Systems (EMS). Those
-capabilities are provided by OpenECOMP. Hence, VNFs are required to
-consume open interfaces to OpenECOMP in support of management and
-control. The VNF Package must include the appropriate data models for
-integration with OpenECOMP to enable management and control of the
-VNFCs.
-
-**Figure 1** shows a simplified OpenECOMP and Infrastructure view to
-highlight how individual Virtual Network Functions plug into the
-OpenECOMP control loops.
-
-|image0|
-
-\ **Figure 1. Control Loop**
-
-In the control loop view in **Figure 1**, the VNF provides an event
-data stream via an API to Data Collection, Analytics and Events (DCAE).
-DCAE analyzes and aggregates the data stream and when particular
-conditions are detected, uses policy to enable what, if any, action
-should be triggered. Some of the triggered actions may require a
-controller to make changes to the VNF through a VNF provided API.

-Appendix C - Comparison between VNF Guidelines and ETSI GS NFV-SWA 001.
-
-Evolving VNF Related Industry Activities
-----------------------------------------
-
-Many existing industry collaboration bodies are structured around a
-particular service or segment of the network. VNFs are intended to
-operate across multiple services and execute on commodity targeted
-virtualization environments. With the NCSPs transformation to acquiring
-products and services based on location and hardware independent VNFs,
-the opportunity exists for instances of those VNFs to be deployed across
-multiple network locations and services where suitable virtualization
-infrastructure is available.
-
-The rise of industry-supported open source communities has created new
-opportunities for collaboration and challenges for existing industry
-communities such as Standards Developing Organizations (SDOs).
-Collaboration in many SDOs defers intellectual property issues. Most
-industrially-supported open source communities resolve intellectual
-property issues between collaborators through explicit contribution
-licensing agreements. Common infrastructure software components (e.g.,
-SDN Controllers, Cloud Management Systems) are expected to be available
-through industrially supported open source communities (e.g., Open
-Daylight and OpenStack). Whether VNFs are open or proprietary, they
-should use open APIs, test and integration capabilities developed in
-industrially supported open source communities (e.g., OpenECOMP, OPNFV).
-
-The migration path for operator’s existing processes and services to
-effectively utilize VNFs may be operator specific. The requirements for
-VNFs may be expected to evolve rapidly as the industry develops
-experience with operational and development best practices for VNFs. In
-particular, industry operations procedures are expected to evolve
-towards agile software methodologies, DevOps, continuous integration and
-continuous deployment (CI/CD). In this environment of changing and
-context-dependent VNF requirements, agile, pragmatic approaches focused
-on delivering functionality in the near term and evolving it towards
-targeted VNF characteristics are preferred over lengthy waterfall
-industry standardization processes. Demonstrating functionality and
-interoperability of appropriate VNF-related APIs in open source
-communities is considered a pre-requisite to starting industry
-specification work documenting stable interfaces.
-
-While multiple open source communities exist supporting particular
-infrastructure software options, the market success of any particular
-option combination cannot be assured. Integration communities such as
-OPNFV provide an approach enabling VNF providers to test their products
-and services against a variety of expected configurations available in
-the industry.
-
-Evolving towards VNFs
----------------------
-
-In order to deploy VNFs, a target virtualization environment must
-already be in place. The NCSPs scale necessitates a phased rollout of
-virtualization infrastructure and then of VNFs upon that infrastructure.
-Some VNF use cases may require greenfield infrastructure deployments,
-others may start brownfield deployments in centralized data centers and
-then scale deployment more widely as infrastructure becomes available.
-Some service providers have been very public and proactive in setting
-transformation targets associated with VNFs [13]_.
-
-Because of the complexity of migration and integration issues, the
-requirements for VNFs in the short term may need to be contextualized to
-the specific service and transition planning.
-
-Much of the existing VNF work has been based on corresponding network
-function definitions and requirements developed for PNFs. Many of the
-assumptions about PNFs do not apply to VNFs and the modularity of the
-functionality is expected to be significantly different. In addition,
-the increased service velocity objectives of NFV are based on new types
-of VNFs being developed to support new services being deployed in
-virtualized environments. Much of the functionality associated with 5G
-(e.g., IoT, augmented reality/virtual reality) is thus expected to be
-deployed as VNFs in targeted virtualization infrastructure towards the
-edge of the network.
-
-VNF Characteristics
-===================
-
-VNFs need to be constructed using a distributed systems architecture
-that we will call "Network Cloud Ready". They need to interact with the
-orchestration and control platform provided by OpenECOMP and address the
-new security challenges that come in this environment.
-
-The main goal of a Network Cloud Ready VNF is to run ‘well’ on any
-Network Cloud (public or private) over any network (carrier or
-enterprise). In addition, for optimal performance and efficiency, VNFs
-will be designed to take advantage of Network Clouds. This requires
-careful engineering in both VNFs and candidate Network Cloud computing
-frameworks.
-
-To ensure Network Cloud capabilities are leveraged and VNF resource
-consumption meets engineering and economic targets, VNF performance and
-efficiency will be benchmarked in a controlled lab environment. In line
-with the principles and practices laid out in ETSI GS NFV-PER 001,
-efficiency testing will consist of benchmarking VNF performance with a
-reference workload and associated performance metrics on a reference
-Network Cloud (or, when appropriate, additional benchmarking on a bare
-metal reference platform).
-
-Network Cloud Ready VNF characteristics and design consideration can be
-grouped into three areas:
-
-- Cloud Readiness
-
-- OpenECOMP Ready
-
-- Virtualization Environment Ready
-
-Detailed requirements are contained in the reference documents that are
-listed in Appendix B - References.
-
-Cloud Readiness
----------------
-
-VNFs should be designed to operate within a cloud environment from the
-first stages of the development. The VNF provider should think clearly
-about how the VNF should be decomposed into various modules. Resiliency
-within a cloud environment is very different than in a physical
-environment and the developer should give early thought as to how the
-Network Cloud Service Provider will ensure the level of resiliency
-required by the VNF and then provide the capabilities needed within that
-VNF. Scaling and Security should also be well thought out at design time
-so that the VNF runs well in a virtualized environment. Finally, the VNF
-Provider also needs to think about how they will integrate and deploy
-new versions of the VNF. Since the cloud environment is very dynamic,
-the developer should utilize DevOps practices to deploy new software.
-
-Requirements for Cloud Readiness can be found in the *VNF Common
-Requirements for OpenECOMP* document.
-
-VNF Design
-~~~~~~~~~~
-
-A VNF may be a large construct and therefore when designing it, it is
-important to think about the components from which it will be composed.
-The ETSI SWA 001 document gives a good overview of the architecture of a
-VNF in Chapter 4 as well as some good examples of how to compose a VNF
-in its Annex B. When laying out the components of the VNF it is
-important to keep in mind the following principles: Single Capability,
-Independence, State and the APIs.
-
-Many Network Clouds will use Heat to describe orchestration templates
-for instantiating VNFs and VNFCs. Heat has a useful abstraction called a
-“module” that can contain one or more VNFCs. A module can be thought of
-as a deployment unit. In general the goal should be for each module to
-contain a single VNFC.
-
-Single Capability
-^^^^^^^^^^^^^^^^^
-
-VNFs should be carefully decomposed into loosely coupled, granular,
-re-usable VNFCs that can be distributed and scaled on a Network Cloud.
-VNFCs should be responsible for a single capability.
-
-The Network Cloud will define several flavors of VMs for a VNF designer
-to choose from for instantiating a VNFC. The best practice is to keep
-the VNFCs as lightweight as possible while still fulfilling the business
-requirements for the "single capability", however the VNFC should not be
-so small that the overhead of constructing, maintaining, and operating
-the service outweighs its utility.
-
-Independence
-^^^^^^^^^^^^
-
-VNFCs should be independently deployed, configured, upgraded, scaled,
-monitored, and administered (by OpenECOMP). The VNFC must be a
-standalone executable process.
-
-API versioning is one of the biggest enablers of independence. To be
-able to independently evolve a component, versioning must ensure
-existing clients of the component are not forced to flash-cut with each
-interface change. API versioning enables smoother evolution while
-preserving backward compatibility.
-
-Scaling
-^^^^^^^
-
-Each VNFC within a VNF must support independent horizontal scaling, by
-adding/removing instances, in response to demand loads on that VNFC. The
-Network Cloud is not expected to support adding/removing resources
-(compute, memory, storage) to an existing instance of a VNFC (vertical
-scaling). A VNF should be designed such that its components can scale
-independently of each other. Scaling one component should not require
-another component to be scaled at the same time. All scaling will be
-controlled by OpenECOMP.
-
-Managing State
-^^^^^^^^^^^^^^
-
-VNFCs and their interfaces should isolate and manage state to allow for
-high-reliability, scalability, and performance in a Network Cloud
-environment. The use of state should be minimized as much as possible to
-facilitate the movement of traffic from one instance of a VNFC to
-another. Where state is required it should be maintained in a
-geographically redundant data store that may in fact be its own VNFC.
-
-This concept of decoupling state data can be extended to all persistent
-data. Persistent data should be held in a loosely coupled database.
-These decoupled databases need to be engineered and placed correctly to
-still meet all the performance and resiliency requirements of the
-service.
-
-Lightweight and Open APIs
-^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Key functions are accessible via open APIs, which align to Industry API
-Standards and supported by an open and extensible information/data
-model.
-
-Reusability
-^^^^^^^^^^^
-
-Properly (de)composing a VNF requires thinking about “reusability”.
-Components should be designed to be reusable within the VNF as well as
-by other VNFs. The “single capability” principle aids in this
-requirement. If a VNFC could be reusable by other VNFs then it should be
-designed as its own single component VNF that may then be chained with
-other VNFs. Likewise, a VNF provider should make use of other common
-platform VNFs such as firewalls and load balancers, instead of building
-their own.
-
-Resiliency
-~~~~~~~~~~
-
-The VNF is responsible for meeting its resiliency goals and must factor
-in expected availability of the targeted virtualization environment.
-This is likely to be much lower than found in a traditional data center.
-The VNF developer should design the function in such a way that if there
-is a platform problem the VNF will continue working as needed and meet
-the SLAs of that function. VNFs should be designed to survive single
-failure platform problems including: hypervisor, server, datacenter
-outages, etc. There will also be significant planned downtime for the
-Network Cloud as the infrastructure goes through hardware and software
-upgrades. The VNF should support tools for gracefully meeting the
-service needs such as methods for migrating traffic between instances
-and draining traffic from an instance. The VNF needs to rapidly respond
-to the changing conditions of the underlying infrastructure.
-
-VNF resiliency can typically be met through redundancy often supported
-by distributed systems architectures. This is another reason for
-favoring smaller VNFCs. By having more instances of smaller VNFCs it is
-possible to spread the instance out across servers, racks, datacenters,
-and geographic regions. This level of redundancy can mitigate most
-failure scenarios and has the potential to provide a service with even
-greater availability than the old model. Careful consideration of VNFC
-modularity also minimizes the impact of failures when an instance does
-fail.
-
-Security
-~~~~~~~~
-
-Security must be integral to the VNF through its design, development,
-instantiation, operation, and retirement phases. VNF architectures
-deliver new security capabilities that make it easier to maximize
-responsiveness during a cyber-attack and minimize service interruption
-to the customers. SDN enables the environment to expand and adapt for
-additional traffic and incorporation of security solutions. Further,
-additional requirements will exist to support new security capabilities
-as well as provide checks during the development and production stages
-to assure the expected advantages are present and compensating controls
-exist to mitigate new risks.
-
-New security requirements will evolve along with the new architecture.
-Initially, these requirements will fall into the following categories:
-
-- VNF General Security Requirements
-
-- VNF Identity and Access Management Requirements
-
-- VNF API Security Requirements
-
-- VNF Security Analytics Requirements
-
-- VNF Data Protection Requirements
-
-DevOps
-~~~~~~
-
-The OpenECOMP software development and deployment methodology is
-evolving toward a DevOps model. VNF development and deployment should
-evolve in the same direction, enabling agile delivering of end-to-end
-services. Following these same principles better positions OpenECOMP and
-VNF development to coevolve in the same direction.
-
-Testing
-^^^^^^^
-
-VNF packages should provide comprehensive automated regression,
-performance and reliability testing with VNFs based on open industry
-standard testing tools and methodologies. VNF packages should provide
-acceptance and diagnostic tests and in-service instrumentation to be
-used in production to validate VNF operation.
-
-Build and Deployment Processes
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-VNF packages should include continuous integration and continuous
-deployment (CI/CD) software artifacts that utilize automated open
-industry standard system and container build tools. The VNF package
-should include parameterized configuration variables to enable automated
-build customization. Don’t create unique (snowflake) VNFs requiring any
-manual work or human attention to deploy. Do create standardized (Lego™)
-VNFs that can be deployed in a fully automated way.
-
-OpenECOMP will orchestrate updates and upgrades of VNFs. The target
-method for updates and upgrades is to onboard and validate the new
-version, then build a new instance with the new version of software,
-transfer traffic to that instance and kill the old instance. There
-should be no need for the VNF or its components to provide an
-update/upgrade mechanism.
-
-Automation
-^^^^^^^^^^
-
-Increased automation is enabled by VNFs and VNF design and composition.
-VNF and VNFCs should provide the following automation capabilities, as
-triggered or managed via OpenECOMP:
-
-- Events and alarms
-
-- Lifecycle events
-
-- Zero-Touch rolling upgrades and downgrades
-
-- Configuration
-
-OpenECOMP Ready
----------------
-
-OpenECOMP is the “brain” providing the lifecycle management and control
-of software-centric network resources, infrastructure and services.
-OpenECOMP is critical in achieving the objectives to increase the value
-of the Network Cloud to customers by rapidly on-boarding new services,
-enabling the creation of a new ecosystem of consumer and enterprise
-services, reducing capital and operational expenditures, and providing
-operations efficiencies. It delivers enhanced customer experience by
-allowing them in near real-time to reconfigure their network, services,
-and capacity.
-
-For more details, refer to the `ECOMP Architecture White
-Paper <http://att.com/ecomp>`__\ [14]_.
-
-One of the main OpenECOMP responsibilities is to rapidly onboard and
-enrich VNFs to be cataloged as resources to allow composition and
-deployment of services in a multi-vendor plug and play environment. It
-is also extremely important to be able to automatically manage the VNF
-run-time lifecycle to fully realize benefits of NFV. The VNF run-time
-lifecycle includes aspects such as instantiation, configuration, elastic
-scaling, automatic recovery from resource failures, and resource
-allocation. It is therefore imperative to provide VNFs that are equipped
-with well-defined capabilities that comply with OpenECOMP standards to
-allow rapid onboarding and automatic lifecycle management of these
-resources when deploying services as depicted in **Figure 2**.
-
-|image1|
-
-\ **Figure 2. VNF Complete Lifecycle Stages**
-
-In order to realize these capabilities within the OpenECOMP platform, it
-is important to adhere to a set of key principles (listed below) for
-VNFs to integrate into OpenECOMP.
-
-Requirements for OpenECOMP Ready can be found in the *VNF Management
-Requirements for OpenECOMP* document.
-
-Design Definition
-~~~~~~~~~~~~~~~~~
-
-Onboarding automation will be facilitated by applying standards-based
-approaches to VNF packaging to describe the VNF’s infrastructure
-resource requirements, topology, licensing model, design constraints,
-and other dependencies to enable successful VNF deployment and
-management of VNF configuration and operational behavior.
-
-The current VNF Package Requirement is based on a subset of the
-Requirements contained in the ETSI Document: ETSI GS NFV-MAN 001 v1.1.1
-and GS NFV IFA011 V0.3.0 (2015-10) - Network Functions Virtualization
-(NFV), Management and Orchestration, VNF Packaging Specification.
-
-Configuration Management
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-OpenECOMP must be able to orchestrate and manage the VNF configuration
-to provide fully automated environment for rapid service provisioning
-and modification. VNF configuration/reconfiguration must be allowed
-directly through standardized APIs without the need for an EMS.
-
-Monitoring and Management
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The end-to-end service reliability and availability in a virtualized
-environment will greatly depend on the ability to monitor and manage the
-behavior of Virtual Network Functions in real-time. OpenECOMP platform
-must be able to monitor the health of the network and VNFs through
-collection of event and performance data directly from network resources
-utilizing standardized APIs without the need for an EMS. The VNF
-provider must provide visibility into VNF performance and fault at the
-VNFC level (VNFC is the smallest granularity of functionality in our
-architecture) to allow OpenECOMP to proactively monitor, test, diagnose
-and trouble shoot the health and behavior of VNFs at their source.
-
-Virtualization Environment Ready
---------------------------------
-
-Every Network Cloud Service Provider will have a different set of
-resources and capabilities for their Network Cloud, but there are some
-common resources and capabilities that nearly every NCSP will offer.
-
-Network Cloud
-~~~~~~~~~~~~~
-
-VNFCs should be agnostic to the details of the Network Cloud (such as
-hardware, host OS, Hypervisor or container technology) and must run on
-the Network Cloud with acknowledgement to the paradigm that the Network
-Cloud will continue to rapidly evolve and the underlying components of
-the platform will change regularly. VNFs should be prepared to move
-VNFCs across VMs, hosts, locations or datacenters, or Network Clouds.
-
-Overlay Network
-~~~~~~~~~~~~~~~
-
-VNFs should be compliant with the Network Cloud network virtualization
-platform including the specific set of characteristics and features.
-
-The Network Cloud is expected to be tuned to support VNF performance
-requirements. Initially, specifics may differ per Network Cloud
-implementation and are expected to evolve over time, especially as the
-technology matures.
-
-Guest Operating Systems
-~~~~~~~~~~~~~~~~~~~~~~~
-
-VNFs should use the NCSP’s standard set of OS images to enable
-compliance with security, audit, regulatory and other needs.
-
-Compute Flavors
-~~~~~~~~~~~~~~~
-
-VNFs should take advantage of the standard Network Cloud capabilities in
-terms of VM characteristics (often referred to as VM Flavors), VM sizes
-and cloud acceleration capabilities aimed at VNFs such as Intel’s Data
-Plane Development Kit (DPDK).
-
-Summary
-=======
-
-The intent of these guidelines and requirements is to provide long term
-vision as well as short term focus and clarity where no current open
-source implementation exists today. The goal is to accelerate the
-adoption of VNFs which will increase innovation, minimize customization
-to onboard VNFs, reduce implementation time and complexity as well as
-lower overall costs for all stakeholders. It is critical for the
-Industry to align on a set of standards and interfaces to quickly
-realize the benefits of NFV. AT&T is contributing these guidelines to
-the OpenECOMP open source community as a step in moving toward
-standards. These guidelines are based on our experience with large scale
-deployment and operations of VNFs over the past several years.
-
-This VNF guidelines document provides a general overview and points to
-more detailed requirements documents. The subtending documents provide
-more detailed requirements and are listed in Appendix B - References.
-All documents are expected to evolve.
-
-Some of these VNF guidelines may be more broadly applicable in the
-industry, e.g., in other open source communities or standards bodies.
-The art of VNF architecture and development is expected to mature
-rapidly with practical deployment and operations experience from a
-broader ecosystem of types of VNFs and different VNF providers.
-Individual operators may also choose to provide their own extensions and
-enhancements to support their particular operational processes, but
-these guidelines are expected to remain broadly applicable across a
-number of service providers interested in acquiring VNFs.
-
-We invite feedback on these VNF Guidelines in the context of the
-OpenECOMP Project. We anticipate an ongoing project within the OpenECOMP
-Community to maintain similar guidance for VNF developers to enable them
-to more easily develop VNFs which are compatible with the evolving
-releases of OpenECOMP. Comments on these guidelines should be discussed
-there.

-Appendix C - Comparison between VNF Guidelines and ETSI GS NFV-SWA 001
-======================================================================
-
-The VNF guidelines presented in this document (VNF Guidelines) overlap
-with the ETSI GS NFV-SWA 001 (Network Functions Virtualization (NFV);
-Virtual Network Function Architecture) document. For convenience we will
-just refer to this document as SWA 001.
-
-The SWA 001 document is a survey of the landscape for architecting a
-VNF. It includes many different options for building a VNF that take
-advantage of the ETSI MANO architecture.
-
-The Network Cloud and OpenECOMP have similarities to ETSI’s MANO, but
-also have differences described in earlier sections. The result is
-differences in the VNF requirements. Since these VNF Guidelines are for
-a specific implementation of an architecture they are narrower in scope
-than what is specified in the SWA 001 document.
-
-The VNF Guidelines primarily overlaps the SWA 001 in Sections 4 and 5.
-The other sections of the SWA 001 document lie outside the scope of the
-VNF Guidelines.
-
-This appendix will describe the differences between these two documents
-indexed on the SWA 001 sections
-
-Section 4 Overview of VNF in the NFV Architecture
--------------------------------------------------
-
-This section provides an overview of the ETSI NFVI architecture and how
-it interfaces with the VNF architecture. Because of the differences
-between infrastructure architectures there will naturally be some
-differences in how it interfaces with the VNF.
-
-A high level view of the differences in architecture can be found in the
-main body of this document and a more detailed analysis can be found in
-the ECOMP Architecture White Paper\ [15]_.
-
-Section 4.3 Interfaces
-~~~~~~~~~~~~~~~~~~~~~~
-
-Since OpenECOMP provides the VNFM and EMS functionality for all VNFs the
-SWA-3 and SWA-4 interfaces are OpenECOMP interfaces. All OpenECOMP
-interfaces are described in this package of documents.
-
-Section 5 VNF Design Patterns and Properties
---------------------------------------------
-
-This section of the SWA 001 document gives a broad view of all the
-possible design patterns of VNFs. The VNF Guidelines do not generally
-differ from this section. The VNF Guidelines address a more specific
-scope than what is allowed in the SWA 001 document.
-
-Section 5.1 VNF Design Patterns
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The following are differences between the VNF Guidelines and SWA-001:
-
-- 5.1.2 - The Network Cloud does not recognize the distinction between
- “parallelizable” and “non-parallelizable” VNFCs, where parallelizable
- means that there can be multiple instances of the VNFC. In the VNF
- Guidelines, all VNFCs should support multiple instances and therefore
- be parallelizable.
-
-- 5.1.3 - The VNF Guidelines encourages the use of stateless VNFCs.
- However, where state is needed it should be kept external to the VNFC
- to enable easier failover
-
-- 5.1.5 - The VNF Guidelines only accepts horizontal scaling (scale
- out/in) by VNFC. Vertical scaling (scale up/down) is not supported by
- OpenECOMP.
-
-- 5.1.5 - Since OpenECOMP provides all EMS and VNFM functionality
- On-Demand scaling is accomplished through OpenECOMP and not directly
- by the VNF
-
-Section 5.2 VNF Update and Upgrade
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-- 5.2.2 - OpenECOMP will orchestrate updates and upgrades. The
- preferred method for updates and upgrades is to build a new instance
- with the new version of software, transfer traffic to that instance
- and kill the old instance
-
-Section 5.3 VNF Properties
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The following are differences between the VNF Guidelines and SWA-001:
-
-- 5.3.1 - In a Network Cloud all VNFs must be only “COTS-Ready”. The
- VNF Guidelines does not support “Partly COTS-READY” or “Hardware
- Dependent”.
-
-- 5.3.2 – The only virtualization environment currently supported by
- OpenECOMP is “Virtual Machines”. The VNF Guidelines state that all
- VNFs should be hypervisor agnostic. Other virtualized environment
- options such as containers are not currently supported. However,
- container technology is targeted to be supported in the future.
-
-- 5.3.3 - All VNFs must scale horizontally (scale out/in) within the
- Network Cloud. Vertical (scale up/down) is not supported.
-
-- 5.3.5 - The VNF Guidelines state that OpenECOMP will provide full
- policy management for all VNFs. The VNF will not provide its own
- policy management for provisioning and management.
-
-- 5.3.7 - The VNF Guidelines recognizes both stateless and stateful
- VNFCs but it encourages the minimization of stateful VNFCs.
-
-- 5.3.11 - The VNF Guidelines only allows for OpenECOMP management of
- the VNF. It does not allow a proprietary management interface for use
- with a 3rd party EMS
-
-Section 5.4 Attributes describing VNF Requirements
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Attributes described in the VNF Guidelines and reference documents
-include those attributes defined in this section of the SWA 001 document
-but also include additional attributes.

-
-Intended Audience
------------------
-
-This document is intended for persons developing Heat templates that
-will be orchestrated by OpenECOMP.
-
-Scope
------
-
-The first implementations of Network Cloud are assumed to be OpenStack
-based and thus OpenECOMP will be supporting Heat Orchestration
-Templates, also referred to as Heat templates or Heat in this document.
-
-OpenECOMP requires the Heat Templates to follow a specific format. This
-document provides the mandatory, recommended, and optional requirements
-associated with this format.
-
-In addition, the OpenStack version deployed in the Network Cloud may
-impose additional constraints on the Heat. These constraints are not
-covered in this document.
-
-VNF Modularity Overview
------------------------
-
-OpenECOMP supports a modular Heat design pattern, referred to as *VNF
-Modularity.* With this approach, a single VNF may be composed from one
-or more Heat templates, each of which represents some subset of the
-overall VNF. These component parts are referred to as “\ *VNF
-Modules*\ ”. During orchestration, these modules may be deployed
-incrementally to build up the complete VNF.
-
-A Heat template can be either one of the following types of modules:
-
-1. Base Module
-
-2. Incremental Modules
-
-3. Independent Cinder Volume Modules
-
-The OpenECOMP Heat template naming convention must be followed (Section
-2.1). The naming convention identifies the module type.
-
-A VNF must be composed of one “base” VNF module (also called a base
-module) and zero to many “incremental” or “add on” VNF modules. The base
-module must be deployed first, prior to the add-on modules.
-
-A module can be thought of as equivalent to a Heat template, where a
-Heat template is composed of a YAML file and an environment file (also
-referred to as an ENV file). A given YAML file must have a corresponding
-environment file; OpenECOMP requires it.
-
-A Heat template is used to create or deploy a Heat stack. Therefore, a
-module is also equivalent to a Heat Stack.
-
-OpenECOMP supports the concept of an optional, independent deployment of
-a Cinder volume via separate Heat templates. This allows the volume to
-persist after VNF deletion so that the volume can be reused on another
-instance (e.g. during a failover activity).
-
-The scope of a volume module, when it exists, must be 1:1 with the VNF
-Module (base or add-on). A single volume module must create only the
-volumes needed by a single VNF module (base or add-on).
-
-These concepts will be described in more detail throughout the document.
-This overview is provided to set the stage and help clarify the concepts
-that will be introduced.
-
-General Guidelines
-==================
-
-The Heat templates supported by OpenECOMP must follow the requirements
-enumerated in this section.
-
-Filenames
----------
-
-In order to enable OpenECOMP to understand the relationship between Heat
-files, the following Heat file naming convention must be followed.
-
-- The file name for the base module Heat template must include “base”
- in the filename.
-
- - Examples: *base\_xyz.yml* or *base\_xyz.yaml*; *xyz\_base.yml* or
- *xyz\_base.yaml*
-
-- There is no explicit naming convention for the add-on modules.
-
- - Examples: *module1.yml* or *module1.yaml*
-
-- All Cinder volume templates must be named the same as the
- corresponding Heat template with “\_volume” appended to the file
- name.
-
- - Examples: *base\_xyz\_volume.yml* or *base\_xyz\_volume.yaml*;
- *xyz\_base\_volume.yml* or *xyz\_base\_volume.yaml*;
- *module1\_volume.yml* or *module1\_volume.yaml* (referencing the
- above base module Heat template name)
-
-- The file name of the environment files must fully match the
- corresponding Heat template filename and have *.env* or *.ENV*
- extension.
-
- - Examples: *base\_xyz.env* or *base\_xyz.ENV*; *xyz\_base.env* or
- *xyz\_base.ENV*; *base\_xyz\_volume.env* or
- *base\_xyz\_volume.ENV*; *module1.env* or *module1.ENV;
- module1\_volume.env* or *module1\_volume.ENV* (referencing the
- above base module Heat template name)
-
-- A YAML file must have a corresponding ENV file, even if the ENV file
- enumerates no parameters. It is an OpenECOMP requirement.
-
-Valid YAML Format
------------------
-
-A Heat template (a YAML file and its corresponding environment file)
-must be formatted in valid YAML. For a description of YAML, refer to the
-following OpenStack wiki:
-https://wiki.openstack.org/wiki/Heat/YAMLTemplates
-
-A Heat template must follow a specific format. The OpenStack Heat
-Orchestration Template (HOT) specification explains in detail all
-elements of the HOT template format.
-http://docs.openstack.org/developer/heat/template_guide/hot_spec.html
-
-Parameter Categories & Specification
-------------------------------------
-
-Parameter Categories
-~~~~~~~~~~~~~~~~~~~~
-
-OpenECOMP requires the Heat template parameters to follow certain
-requirements in order for it to be orchestrated or deployed. OpenECOMP
-classifies parameters into eight broad categories.
-
-- **OpenECOMP Metadata**: OpenECOMP mandatory and optional metadata
- parameters in the resource *OS::Nova::Server*.
-
- - OpenECOMP dictates the naming convention of these Metadata
- parameters and must be adhered to (See Section 4.4).
-
- - Metadata parameters must not be enumerated in the environment
- file.
-
- - The OpenECOMP Metadata are generated and/or assigned by OpenECOMP
- and supplied to the Heat by OpenECOMP at orchestration time.
-
-- **OpenECOMP Orchestration Parameters**: The data associated with
- these parameters are VNF instance specific.
-
- - OpenECOMP enforces the naming convention of these parameters and
- must be adhered to (See Section 4).
-
- - These parameters must not be enumerated in the environment file.
-
- - The OpenECOMP Orchestration Parameters are generated and/or
- assigned by OpenECOMP and supplied to the Heat by OpenECOMP at
- orchestration time.
-
-- **VNF Orchestration Parameters**: The data associated with these
- parameters are VNF instance specific.
-
- - While OpenECOMP does not enforce a naming convention, the
- parameter names should include {vm-type} and {network-role} when
- appropriate. (See Section 4)
-
- - These parameters must not be enumerated in the environment file.
-
- - The VNF Orchestration Parameters Heat are generated and/or
- assigned by OpenECOMP and supplied to the Heat by OpenECOMP at
- orchestration time.
-
-- **OpenECOMP Orchestration Constants**: The data associated with these
- parameters must be constant across all VNF instances.
-
- - OpenECOMP enforces the naming convention of these parameters and
- must be adhered to (See Section 4).
-
- - These parameters must be enumerated in the environment file.
-
-- **VNF Orchestration Constants**: The data associated with these
- parameters must be constant across all VNF instances.
-
- - While OpenECOMP does not enforce a naming convention, the
- parameter names should include {vm-type} and {network-role} when
- appropriate. (See Section 4)
-
- - These parameters must be enumerated in the environment file.
-
-- **OpenECOMP Base Template Output Parameters** (also referred to as
- Base Template Output Parameters): The output section of the base
- template allows for specifying output parameters available to add-on
- modules once the base template has been instantiated. The parameter
- defined in the output section of the base must be identical to the
- parameter defined in the add-on module(s) where the parameter is
- used.
-
-- **OpenECOMP Volume Template Output Parameters** (also referred to as
- Volume Template Output Parameters): The output section of the volume
- template allows for specifying output parameters available to the
- corresponding Heat template (base or add-on) once the volume template
- has been instantiated. The parameter defined in the output section of
- the volume must be identical to the parameter defined in the base or
- add-on module.
-
-- **OpenECOMP Predefined Output Parameters** (also referred to as
- Predefined Output Parameters): OpenECOMP will look for a small set of
- pre-defined Heat output parameters to capture resource attributes for
- inventory in OpenECOMP. These parameters are specified in Section
- 4.6.
-
-The table below summarizes the Parameter Types. If the user is
-orchestrating a manual spin up of Heat (e.g. OpenStack command line),
-the parameter values that OpenECOMP supplies must be enumerated in the
-environment file. However, when the Heat is to be loaded into OpenECOMP
-for orchestration, the parameters that OpenECOMP supplies must be
-deleted or marked with a comment (i.e., a “#” placed at the beginning of
-a line).

-Table 1 Parameter Types
-
-Parameter Specifications
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-OpenECOMP METADATA Parameters
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-OpenECOMP defines four “metadata” parameters: vnf\_id, vf\_module\_id,
-vnf\_name, vf\_module\_name. These parameters must not define any
-constraints in the Heat template, including length restrictions, ranges,
-default value and/or allowed patterns.
-
-OpenECOMP Base Template & Volume Template Output Parameters
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The base template and volume template output parameters are defined as
-input parameters in subsequent modules. When defined as input
-parameters, these parameters must not define any constraints in the Heat
-template, including length restrictions, ranges, default value and/or
-allowed patterns. The parameter name defined in the output statement of
-the Heat must be identical to the parameter name defined in the Heat
-that is to receive the value.
-
-OpenECOMP Predefined Output Parameters
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-These parameters must not define any constraints in the Heat template,
-including length restrictions, ranges, default value and/or allowed
-patterns.
-
-OpenECOMP Orchestration Parameters, VNF Orchestration Parameters, OpenECOMP Orchestration Constants, VNF Orchestration Constants
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-OpenECOMP Orchestration Parameters, VNF Orchestration Parameters,
-OpenECOMP Orchestration Constants, VNF Orchestration Constants must
-adhere to the following:
-
-- All parameters should be clearly documented in the template,
- including expected values.
-
-- All parameters should be clearly specified, including constraints and
- description.
-
-- Numeric parameter constraints should include range and/or allowed
- values.
-
-- When the parameter type is a string and the parameter name contains
- an index, the index must be zero based. That is, the index starts at
- zero.
-
-- When the parameter type is a Comma Delimited List (CDL), the
- reference index must start at zero.
-
-- Default values must only be supplied in a Heat environment file to
- keep the template itself as clean as possible.
-
-- Special characters must not be used in parameter names, as currently
- only alphanumeric characters and “\_” underscores are allowed.
-
-Use of Heat Environments
-------------------------
-
-A YAML file must have a corresponding environment file (also referred to
-as ENV file), even if the environment file defines no parameters. It is
-an OpenECOMP requirement.
-
-The environment file must contain parameter values for the OpenECOMP
-Orchestration Constants and VNF Orchestration Constants. These
-parameters are identical across all instances of a VNF type, and
-expected to change infrequently. The OpenECOMP Orchestration Constants
-are associated with OS::Nova::Server image and flavor properties (See
-Section 4.3). Examples of VNF Orchestration Constants are the networking
-parameters associated with an internal network (e.g. private IP ranges)
-and Cinder volume sizes.
-
-The environment file must not contain parameter values for parameters
-that are instance specific (OpenECOMP Orchestration Parameters, VNF
-Orchestration Parameters). These parameters are supplied to the Heat by
-OpenECOMP at orchestration time. The parameters are generated and/or
-assigned by OpenECOMP at orchestration time
-
-Independent Volume Templates
-----------------------------
-
-OpenECOMP supports independent deployment of a Cinder volume via
-separate Heat templates. This allows the volume to persist after VNF
-deletion so that they can be reused on another instance (e.g. during a
-failover activity).
-
-A VNF Incremental Module or Base Module may have an independent volume
-module. Use of separate volume modules is optional. A Cinder volume may
-be embedded within the Incremental or Base Module if persistence is not
-required.
-
-If a VNF Incremental Module or Base Module has an independent volume
-module, the scope of volume templates must be 1:1 with Incremental
-module or Base module. A single volume module must create only the
-volumes required by a single Incremental module or Base module.
-
-The following rules apply to independent volume Heat templates:
-
-- Cinder volumes must be created in a separate Heat template from the
- Incremental and Base Modules.
-
- - A single volume module must include all Cinder volumes needed by
- the Incremental/Base module.
-
- - The volume template must define “outputs” for each Cinder volume
- resource universally unique identifier (UUID) (i.e. OpenECOMP
- Volume Template Output Parameters).
-
-- The VNF Incremental Module or Base Module must define input
- parameters that match each Volume output parameter (i.e., OpenECOMP
- Volume Template Output Parameters).
-
- - OpenECOMP will supply the volume template outputs automatically to
- the bases/incremental template input parameters.
-
-- Volume modules may utilize nested Heat templates.
-
-**Example (volume template):**
-
- In this example, the {vm-type} has been left as a variable.
- {vm-type} is described in section 4.1. If the VM was a load
- balancer, the {vm-type} could be defined as “lb”
-
-.. code-block:: yaml
-
- parameters:
- vm-typevnf\_name:
- type: string
- {vm-type}\_volume\_size\_0:

- type: OS::Cinder::VolumeAttachment
- properties:
- instance\_uuid: { get\_resource: {vm-type}\_0 }
- volume\_id: { get\_param: {vm-type}\_volume\_id\_0 }
-
-Nested Heat Templates
----------------------
-
-OpenECOMP supports nested Heat templates per the OpenStack
-specifications. Nested templates may be suitable for larger VNFs that
-contain many repeated instances of the same VM type(s). A common usage
-pattern is to create a nested template for each VM type along with its
-supporting resources. The master VNF template (or VNF Module template)
-may then reference these component templates either statically (by
-repeated definition) or dynamically (via *OS::Heat::ResourceGroup*).
-
-Nested template support in OpenECOMP is subject to the following
-limitations:
-
-- Heat templates for OpenECOMP must only have one level of nesting.
- OpenECOMP only supports one level of nesting.
-
-- Nested templates must be referenced by file name in the master
- template
-
- - i.e. use of *resource\_registry* in the .env file is *not*
- currently supported
-
-- Nested templates must have unique file names within the scope of the
- VNF
-
-- OpenECOMP does not support a directory hierarchy for nested
- templates. All templates must be in a single, flat directory (per
- VNF)
-
-- A nested template may be shared by all Modules (i.e., Heat templates)
- within a given VNF
-
-Networking
-===========
-
-External Networks
------------------
-
-VNF templates must not include any resources for external networks
-connected to the VNF. In this context, “external” is in relation to the
-VNF itself (not with regard to the Network Cloud site). External
-networks may also be referred to as “inter-VNF” networks.
-
-- External networks must be orchestrated separately, so they can be
- shared by multiple VNFs and managed independently. When the external
- network is created, it must be assigned a unique {network-role} (See
- section 4.2).
-
-- External networks must be passed into the VNF template as parameters,
- including the network-id (i.e. the neutron network UUID) and optional
- subnet ID.
-
-- VNF templates must pass the appropriate external network IDs into
- nested VM templates when nested Heat is used.
-
-- VNFs may use DHCP assigned IP addresses or assign fixed IPs when
- attaching VMs to an external network.
-
-- OpenECOMP enforces a naming convention for parameters associated with
- external networks.
-
-- Parameter values associated with an external network will be
- generated and/or assigned by OpenECOMP at orchestration time.
-
-- Parameter values associated with an external network must not be
- enumerated in the environment file.
-
-Internal Networks
------------------
-
-Orchestration activities related to internal networks must be included
-in VNF templates. In this context, “internal” is in relation to the VNF
-itself (not in relation to the Network Cloud site). Internal networks
-may also be referred to as “intra-VNF” networks or “private” networks.
-
-- Internal networks must not attach to any external gateways and/or
- routers. Internal networks are for intra-VM communication only.
-
-- In the modular approach, internal networks must be created in the
- Base Module template, with their resource IDs exposed as outputs
- (i.e., OpenECOMP Base Template Output Parameters) for use by all
- add-on module templates. When the external network is created, it
- must be assigned a unique {network-role} (See section 4.2).
-
-- VNFs may use DHCP assigned IP addresses or assign fixed IPs when
- attaching VMs to an internal network.
-
-- OpenECOMP does not enforce a naming convention for parameters for
- internal network, however, a naming convention is provided that
- should be followed.
-
-- Parameter values associated with an internal network must either be
- passed as output parameter from the base template (i.e., OpenECOMP
- Base Template Output Parameters) into the add-on modules or be
- enumerated in the environment file.
-
-IP Address Assignment
----------------------
-
-- VMs connect to external networks using either fixed (e.g. statically
- assigned) IP addresses or DHCP assigned IP addresses.
-
-- VMs connect to internal networks using either fixed (e.g. statically
- assigned) IP addresses or DHCP assigned IP addresses.
-
-- Neutron Floating IPs must not be used. OpenECOMP does not support
- Neutron Floating IPs.
-
-- OpenECOMP supports the OS::Neutron::Port property
- “allowed\_address\_pairs.” See Section 4.4.3.
-
-Parameter Naming Convention
-===========================
-
-{vm-type}
----------
-
-A common *{vm-type}* identifier must be used throughout the Heat
-template in naming parameters, for each VM type in the VNF with the
-following exceptions:
-
-- The four OpenECOMP Metadata parameters must not be prefixed with a
- common {vm-type} identifier. They are *vnf\_name*, *vnf\_id*,
- *vf\_module\_id*, *vf\_module\_name*.
-
-- Parameters only referring to a network or subnetwork must not be
- prefixed with a common {vm-type} identifier.
-
-- The parameter referring to the OS::Nova::Server property
- availability\_zone must not be prefixed with a common {vm-type}
- identifier.
-
-- {vm-type} must be unique to the VNF. It does not have to be globally
- unique across all VNFs that OpenECOMP supports.
-
-{network-role}
---------------
-
-VNF templates must not include any resources for external networks
-connected to the VNF. In this context, “external” is in relation to the
-VNF itself (not with regard to the Network Cloud site). External
-networks may also be referred to as “inter-VNF” networks.
-
-External networks must be orchestrated separately, so they can be shared
-by multiple VNFs and managed independently. When the external network is
-created, it must be assigned a unique {network-role}.
-
-“External” networks must be passed into the VNF template as parameters.
-Examples include the network-id (i.e. the neutron network UUID) and
-optional subnet ID. See section 4.4.3.
-
-Any parameter that is associated with an external network must include
-the {network-role} as part of the parameter name.
-
-Internal network parameters must also define a {network-role}. Any
-parameter that is associated with an internal network must include
-int\_{network-role} as part of the parameter name.
-
-Resource: OS::Nova::Server - Parameters
----------------------------------------
-
-The following OS::Nova::Server Resource Property Parameter Names must
-follow the OpenECOMP parameter Naming Convention. All the parameters
-associated with OS::Nova::Server are classified as OpenECOMP
-Orchestration Parameters.

-Table 2 Resource Property Parameter Names
-
-Property: image
-~~~~~~~~~~~~~~~
-
-Image is an OpenECOMP Orchestration Constant parameter. The image must
-be referenced by the Network Cloud Service Provider (NCSP) image name,
-with the parameter enumerated in the Heat environment file.
-
-The parameters must be named *“{vm-type}\_image\_name”* in the VNF.
-
-Each VM type (e.g., {vm-type}) should have a separate parameter for
-images, even if several share the same image. This provides maximum
-clarity and flexibility.
-
-Property: flavor
-~~~~~~~~~~~~~~~~
-
-Flavor is an OpenECOMP Orchestration Constant parameter. The flavors
-must be referenced by the Network Cloud Service Provider (NCSP) flavor
-name, with the parameter enumerated in the Heat environment file.
-
-The parameters must be named *“{vm-type}\_flavor\_name”* for each
-*{vm-type}* in the VNF.
-
-Each VM type should have separate parameters for flavors, even if more
-than one VM shares the same flavor. This provides maximum clarity and
-flexibility.
-
-Property: Name
-~~~~~~~~~~~~~~
-
-Name is an OpenEOMP Orchestration parameter; the value is provided to
-the Heat template by OpenECOMP.
-
-VM names (hostnames) for assignment to VM instances must be passed to
-Heat templates either as
-
-- an array (comma delimited list) for each VM type
-
-- a set of fixed-index parameters for each VM type instance.
-
-Each element in the VM Name list should be assigned to successive
-instances of that VM type.
-
-The parameter names must reflect the VM Type (i.e., include the
-{vm-type} in the parameter name.) The parameter name format must be one
-of the following:
-
-- If the parameter type is a comma delimited list: {**vm-type**}\_names
-
-- If the parameter type is a string with a fixed index:
- {**vm-type**}\_name\_{**index**}
-
-If a VNF contains more than three instances of a given {vm-type}, the
-CDL form of the parameter name (i.e., *{vm-type}*\ \_names} should be
-used to minimize the number of unique parameters defined in the Heat.
-
-*Examples:*

-Property: availability\_zone
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Availability\_zone is an OpenECOMP Orchestration parameter; the value is

- (e.g., <STACK\_NAME>) in the command “Heat stack-create” (e.g.
- Heat stack-create [-f <FILE>] [-e <FILE>] <STACK\_NAME>). The
- <STACK\_NAME> needs to be specified as part of the orchestration
- process.
-
- - *“vf\_module\_name”* parameter value, when used, will be supplied

-
-Property: network & subnet
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The property “networks” in the resource OS::Neutron::Port must be

- type: string
- description: Neutron UUID for the {network-role} network
- {network-role}\_net\_name:
- type: string
- description: Neutron name for the {network-role} network

-
-*Example:*
-
-In this example, the {network-role} has been defined as “oam” to
-represent an oam network and the {vm-type} has been defined as “lb” for
-load balancer.
-
-.. code-block:: yaml
-
- parameters:
- oam\_net\_id:
- type: string
- description: Neutron UUID for the oam network
-
- resources:
- lb\_port\_1:
- type: OS::Neutron::Port
- network: { get\_param: oam\_net\_id }
-
-Property: fixed\_ips
-~~~~~~~~~~~~~~~~~~~~
-
-The property “fixed\_ips” in the resource OS::Neutron::Port must be used
-when statically assigning IP addresses.
-
-An IP address is assigned to a port on a type of VM (i.e., {vm-type})
-that is connected to a type of network (i.e., {network-role}). These two
-tags are components of the parameter name.
-
-When the “fixed\_ips” parameter is referencing an “external” network,
-the parameter must adhere to the naming convention below. The parameter
-may be a comma delimited list or a string.
-
-There must be a different parameter name for IPv4 IP addresses and IPv6
-addresses
-
-- **Comma-delimited list:** Each element in the IP list should be
- assigned to successive instances of that VM type on that network.
-
- - *Format for IPv4 addresses:* {vm-type}\_{network-role}\_ips
-
- - *Format for IPv6 addresses:* {vm-type}\_{network-role}\_v6\_ips
-
-- **A set of fixed-index parameters:** In this case, the parameter
- should have “\ *type: string*\ ” and must be repeated for every IP
- expected for each {vm-type} + {network-role} pair.
-
- - *Format for IPv4 addresses:*
- {vm-type}\_{network-role}\_ip\_{index}
-
- - *Format for IPv6 addresses:*
- {vm-type}\_{network-role}\_v6\_ip\_{index}
-
-When the “fixed\_ips” parameter is referencing an “internal” network,
-the parameter must adhere to the naming convention below. The parameter
-may be a comma delimited list or a string.
-
-There must be a different parameter name for IPv4 IP addresses and IPv6
-addresses
-
-- **Comma-delimited list:** Each element in the IP list should be
- assigned to successive instances of that VM type on that network.
-
- - *Format for IPv4 addresses:* {vm-type}\_int\_{network-role}\_ips
-
- - *Format for IPv6 addresses:*
- {vm-type}\_int\_{network-role}\_v6\_ips
-
-- **A set of fixed-index parameters:** In this case, the parameter
- should have “\ *type: string*\ ” and must be repeated for every IP
- expected for each {vm-type} and {network-role}pair.
-
- - *Format for IPv4 addresses:*
- {vm-type}\_int\_{network-role}\_ip\_{index}
-
- - *Format for IPv6 addresses:*
- {vm-type}\_int\_{network-role}\_v6\_ip\_{index}
-
-If a VNF contains more than three IP addresses for a given {vm-type} and
-{network-role} combination, the CDL form of the parameter name should be
-used to minimize the number of unique parameters defined in the Heat.
-
-*Example (external network)*

-
- parameters:
- {vm-type}\_{network-role}\_ips:

- network: { get\_param: oam\_net\_id }
- fixed\_ips: [ { “ip\_address”: {get\_param: db\_oam\_ip\_1}}]
-
-Property: allowed\_address\_pairs
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The property “allowed\_address\_pairs” in the resource OS::Neutron::Port
-allows the user to specify mac\_address/ip\_address (CIDR) pairs that
-pass through a port regardless of subnet. This enables the use of
-protocols such as VRRP, which floats an IP address between two instances
-to enable fast data plane failover. An “allowed\_address\_pairs” is
-unique to a {vm-type} and {network-role} combination. The management of
-these IP addresses (i.e. transferring ownership between active and
-standby VMs) is the responsibility of the application itself.
-
-Note that these parameters are *not* intended to represent Neutron
-“Floating IP” resources, for which OpenStack manages a pool of public IP
-addresses that are mapped to specific VM ports. In that case, the
-individual VMs are not even aware of the public IPs, and all assignment
-of public IPs to VMs is via OpenStack commands. OpenECOMP does not
-support Neutron-style Floating IPs.
-
-Both IPv4 and IPv6 “allowed\_address\_pairs” addresses are supported.
-
-If property “allowed\_address\_pairs” is used with an external network,
-the parameter name must adhere to the following convention:
-
-- *Format for IPv4 addresses: {vm-type}\_{network-role}\_floating\_ip*
-
-- *Format for IPv6 addresses:
- {vm-type}\_{network-role}\_floating\_v6\_ip*
-
-*Example:*
-
-.. code-block:: yaml
-
- parameters:
- {vm-type}\_{network-role}\_floating\_ip:
- type: string
- description: VIP for {vm-type} VMs on the {network-role} network
- {vm-type}\_{network-role}\_floating\_v6\_ip:
- type: string
- description: VIP for {vm-type} VMs on the {network-role} network
-
-*Example:*
-
-In this example, the {network-role} has been defined as “oam” to
-represent an oam network and the {vm-type} has been defined as “db” for
-database.

- db\_0\_port\_0:
- type: OS::Neutron::Port
- network: { get\_param: oam\_net\_id }
- fixed\_ips: [ { “ip\_address”: {get\_param: [db\_oam\_ips,0] }}]
- allowed\_address\_pairs: [
- { “ip\_address”: {get\_param: db\_oam\_floating\_ip}}]
- db\_1\_port\_0:

- fixed\_ips: [ { “ip\_address”: {get\_param: [db\_oam\_ips,1] }}]
- allowed\_address\_pairs: [
- { “ip\_address”: {get\_param: db\_oam\_floating\_ip}}]
-
-If property “allowed\_address\_pairs” is used with an internal network,
-the parameter name should adhere to the following convention:
-
-- *Format for IPv4 addresses:
- {vm-type}\_int\_{network-role}\_floating\_ip*
-
-- *Format for IPv6 addresses:
- {vm-type}\_int\_{network-role}\_floating\_v6\_ip*
-
-Using the parameter *{vm-type}\_{network-role}\_floating\_ip* or
-*{vm-type}\_{network-role}\_floating\_v6\_ip* provides only one floating
-IP per Vm-type{vm-type} and {network-role} pair. If there is a need for
-multiple floating IPs (e.g., Virtual IPs (VIPs)) for a given {vm-type}
-and {network-role} combination within a VNF, then the parameter names
-defined for the “fixed\_ips” should be used with the
-“allowed\_address\_pairs” property. The examples below illustrate this.
-
-Below example reflects two load balancer pairs in a single VNF. Each
-pair has one VIP.
-
-*Example: A VNF has four load balancers. Each pair has a unique VIP.*
-
-*Pair 1:* lb\_0 and lb\_1 share a unique VIP
-
-*Pair 2:* lb\_2 and lb\_3 share a unique VIP
-
-In this example, the {network-role} has been defined as “oam” to
-represent an oam network and the {vm-type} has been defined as “lb” for
-load balancer.

-
-Below example reflects a single app VM pair within a VNF with two VIPs: 
-
-*Example: A VNF has two load balancers. The pair of load balancers share
-two VIPs.*
-
-In this example, the {network-role} has been defined as “oam” to

-
-As a general rule, provide the fixed IPs for the VMs indexed first in
-the CDL and then the VIPs as shown in the examples above.
-
-Resource Property: name
------------------------
-
-The parameter naming standard for the resource OS::Nova::Server has been
-defined in Section 4.3.3. This section describes how the name property
-of all other resources must be defined.
-
-Heat templates must use the Heat “str\_replace” function in conjunction
-with the OpenECOMP supplied metadata parameter *vnf\_name* or
-*vnf\_module\_id* to generate a unique name for each VNF instance. This
-prevents the use of unique parameters values for resource “name”
-properties to be enumerated in a per instance environment file.
-
-Note that
-
-- In most cases, only the use of the vnf\_name is necessary to create a
- unique name
-
-- the Heat pseudo parameter 'OS::stack\_name’ can also be used in the
- ‘str\_replace’ construct to generate a unique name when the vnf\_name
- does not provide uniqueness
-
-.. code-block:: yaml
-
- type: OS::Cinder::Volume
- properities:
- name:
- str\_replace:
-          template: VF\_NAME\_STACK\_NAME\_oam\_volume
-           params:
-             VF\_NAME: { get\_param: vnf\_name }
-             STACK\_NAME: { get\_param: 'OS::stack\_name'  }
-

-
-Output Parameters
------------------
-
-OpenECOMP defines three type of Output Parameters.
-
-Base Template Output Parameters:
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The base template output parameters are available for use as input
-parameters in all add-on modules. The add-on modules may (or may not)
-use these parameters.
-
-Volume Template Output Parameters:
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The volume template output parameters are only available only for the
-module (base or add on) that the volume is associated with.
-
-Predefined Output Parameters
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-OpenECOMP currently defines one predefined output parameter.
-
-OAM Management IP Addresses
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Many VNFs will have a management interface for application controllers
-to interact with and configure the VNF. Typically, this will be via a
-specific VM that performs a VNF administration function. The IP address
-of this interface must be captured and inventoried by OpenECOMP. This
-might be a VIP if the VNF contains an HA pair of management VMs, or may
-be a single IP address assigned to one VM.
-
-The Heat template may define either (or both) of the following Output
-parameters to identify the management IP address.
-
-- *oam\_management\_v4\_address*
-
-- *oam\_management\_v6\_address*
-
-*Notes*:
-
-- The Management IP Address should be defined only once per VNF, so it
- would only appear in one Module template
-
-- If a fixed IP for the admin VM is passed as an input parameter, it
- may be echoed in the output parameters
-
-- If the IP for the admin VM is obtained via DHCP, it may be obtained
- from the resource attributes
-
-*Example:*
-
-.. code-block:: yaml
-
- resources:
- admin\_server:
- type: OS::Nova::Server
- properties:
- networks:
- - network: {get\_param: oam\_net\_id }
- ...
-
- Outputs:
- oam\_management\_v4\_address:
- value: {get\_attr: [admin\_server, networks, {get\_param: oam\_net\_id}, 0] }
-
-Heat Template Constructs
-========================
-
-External References
--------------------
-
-Heat templates *should not* reference any HTTP-based resource
-definitions, any HTTP-based nested configurations, or any HTTP-based
-environment files.
-
-- During orchestration, OpenECOMP *should not* retrieve any such
- resources from external/untrusted/unknown sources.
-
-- VNF images should not contain such references in user-data or other
- configuration/operational scripts that are specified via Heat or
- encoded into the VNF image itself.
-
-*Note:* HTTP-based references are acceptable if the HTTP-based reference
-is accessing information with the VM private/internal network.
-
-Heat Files Support (get\_file)
-------------------------------
-
-Heat Templates may contain the inclusion of text files into Heat
-templates via the Heat “get\_file” directive. This may be used, for
-example, to define a common “user-data” script, or to inject files into
-a VM on startup via the “personality” property.
-
-Support for Heat Files is subject to the following limitations:
-
-- The ‘get\_files’ targets must be referenced in Heat templates by file
- name, and the corresponding files should be delivered to OpenECOMP
- along with the Heat templates.
-
- - URL-based file retrieval must not be used; it is not supported.
-
-- The included files must have unique file names within the scope of
- the VNF.
-
-- OpenECOMP does not support a directory hierarchy for included files.
-
- - All files must be in a single, flat directory per VNF.
-
-- Included files may be used by all Modules within a given VNF.
-
-- get\_file directives may be used in both non-nested and nested
- templates
-
-Use of Heat ResourceGroup
--------------------------
-
-The *OS::Heat::ResourceGroup* is a useful Heat element for creating
-multiple instances of a given resource or collection of resources.
-Typically it is used with a nested Heat template, to create, for
-example, a set of identical *OS::Nova::Server* resources plus their
-related *OS::Neutron::Port* resources via a single resource in a master
-template.
-
-*ResourceGroup* may be used in OpenECOMP to simplify the structure of a
-Heat template that creates multiple instances of the same VM type.
-However, there are important caveats to be aware of.
-
-*ResourceGroup* does not deal with structured parameters
-(comma-delimited-list and json) as one might typically expect. In
-particular, when using a list-based parameter, where each list element
-corresponds to one instance of the *ResourceGroup*, it is not possible
-to use the intrinsic “loop variable” %index% in the *ResourceGroup*
-definition.
-
-For instance, the following is **not** valid Heat for a *ResourceGroup*:
-
-.. code-block:: yaml
-
- type: OS::Heat::ResourceGroup
- resource:
-      type: my\_nested\_vm\_template.yaml
-      properties:
-          name: {get\_param: [vm\_name\_list, %index%]}
-
-Although this appears to use the nth entry of the *vm\_name\_list* list
-for the nth element of the *ResourceGroup*, it will in fact result in a
-Heat exception. When parameters are provided as a list (one for each
-element of a *ResourceGroup*), you must pass the complete parameter to
-the nested template along with the current index as separate parameters.
-
-Below is an example of an **acceptable** Heat Syntax for a
-*ResourceGroup*:
-
-.. code-block:: yaml
-
- type: OS::Heat::ResourceGroup
- resource:
-     type: my\_nested\_vm\_template.yaml
-     properties:
-         names: {get\_param: vm\_name\_list}
-         index: %index%
-
-You can then reference within the nested template as:
-
-{ get\_param: [names, {get\_param: index} ] }
-
-Note that this is workaround has very important limitations. Since the
-entire list parameter is passed to the nested template, any change to
-that list (e.g., adding an additional element) will cause Heat to treat
-the entire parameter as updated within the context of the nested
-template (i.e., for each *ResourceGroup* element).  As a result, if
-*ResourceGroup* is ever used for scaling (e.g., increment the count and
-include an additional element to each list parameter), Heat will often
-rebuild every existing element in addition to adding the “deltas”. For
-this reason, use of *ResourceGroup* for scaling in this manner is not
-supported.
-
-Key Pairs
----------
-
-When Nova Servers are created via Heat templates, they may be passed a
-“keypair” which provides an ssh key to the ‘root’ login on the newly
-created VM. This is often done so that an initial root key/password does
-not need to be hard-coded into the image.
-
-Key pairs are unusual in OpenStack, because they are the one resource
-that is owned by an OpenStack User as opposed to being owned by an
-OpenStack Tenant. As a result, they are usable only by the User that
-created the keypair. This causes a problem when a Heat template attempts
-to reference a keypair by name, because it assumes that the keypair was
-previously created by a specific OpenECOMP user ID.
-
-When a keypair is assigned to a server, the SSH public-key is
-provisioned on the VMs at instantiation time. They keypair itself is not
-referenced further by the VM (i.e. if the keypair is updated with a new
-public key, it would only apply to subsequent VMs created with that
-keypair).
-
-Due to this behavior, the recommended usage of keypairs is in a more
-generic manner which does not require the pre-requisite creation of a
-keypair. The Heat should be structured in such a way as to:
-
-- Pass a public key as a parameter value instead of a keypair name
-
-- Create a new keypair within the VNF Heat templates (in the base
- module) for use within that VNF
-
-By following this approach, the end result is the same as pre-creating
-the keypair using the public key – i.e., that public key will be
-provisioned in the new VM. However, this recommended approach also makes
-sure that a known public key is supplied (instead of having OpenStack
-generate a public/private pair to be saved and tracked outside of
-OpenECOMP). It also removes any access/ownership issues over the created
-keypair.
-
-The public keys may be enumerated as a VNF Orchestration Constant in the
-environment file (since it is public, it is not a secret key), or passed
-at run-time as an instance-specific parameters. OpenECOMP will never
-automatically assign a public/private key pair.
-
-*Example (create keypair with an existing ssh public-key for {vm-type}
-of lb (for load balancer)):*
-
-.. code-block:: yaml
-
- parameters:
- vnf\_name:
- type: string
- ssh\_public\_key:
- type: string
- resources:
- my\_keypair:
- type: OS::Nova::Keypair
- properties:
- name:
- str\_replace:
- template: VNF\_NAME\_key\_pair
- params:
- VNF\_NAME: { get\_param: vnf\_name }
- public\_key: {get\_param: lb\_ssh\_public\_key}
- save\_private\_key: false
-
-Security Groups
----------------
-
-OpenStack allows a tenant to create Security groups and define rules
-within the security groups.
-
-Security groups, with their rules, may either be created in the Heat
-template or they can be pre-created in OpenStack and referenced within
-the Heat template via parameter(s). There can be a different approach
-for security groups assigned to ports on internal (intra-VNF) networks
-or external networks (inter-VNF). Furthermore, there can be a common
-security group across all VMs for a specific network or it can vary by
-VM (i.e., {vm-type}) and network type (i.e., {network-role}).
-
-Anti-Affinity and Affinity Rules
---------------------------------
-
-Anti-affinity or affinity rules are supported using normal OpenStack
-*“OS::Nova::ServerGroup”* resources. Separate ServerGroups are typically
-created for each VM type to prevent them from residing on the same host,
-but they can be applied to multiple VM types to extend the
-affinity/anti-affinity across related VM types as well.
-
-*Example:*
-
-In this example, the {network-role} has been defined as “oam” to
-represent an oam network and the {vm-type} have been defined as “lb” for
-load balancer and “db” for database.
-
-.. code-block:: yaml
-
- resources:
- db\_server\_group:
- type: OS::Nova::ServerGroup
- properties:
- name:
- str\_replace:
- params:
- $vnf\_name: {get\_param: vnf\_name}

-
-Design Pattern: VNF Modularity
-==============================
-
-OpenECOMP supports the concept of *VNF Modularity*. With this approach,
-a single VNF may be composed from one or more Heat templates, each of
-which represents some subset of the overall VNF. These component parts
-are referred to as “\ *VNF Modules*\ ”. During orchestration, these
-modules may be deployed incrementally to build up the complete VNF.
-
-A Heat template can be either one for the following types of modules
-
-1. Base Module
-
-2. Incremental Modules
-
-3. Independent Cinder Volume Modules
-
-The OpenECOMP Heat template naming convention must be followed (Section
-2.1). The naming convention identifies the module type.
-
-A VNF must be composed of one “base” VNF module (also called a base
-module) and zero to many “incremental” or “add on” VNF modules. The base
-module must be deployed first prior to the add-on modules.
-
-A module can be thought of as equivalent to a Heat template, where a
-Heat template is composed of a YAML file and an environment file. A
-given YAML file must have a corresponding environment file; OpenECOMP
-requires it. A Heat template is used to create or deploy a Heat stack.
-Therefore, a module is also equivalent to a Heat Stack.
-
-However, there are cases where a module maybe composed of more than one
-Heat stack and/or more than one YAML file.
-
-As discussed in Section 2.5, Independent Volume Templates, each VNF
-Module may have an associated Volume template.
-
-- When a volume template is utilized, it must correspond 1:1 with
- add-on module template or base template it is associated with
-
-- A Cinder volume may be embedded within the add-on module template
- and/or base template if persistence is not required, thus not
- requiring the optional Volume template.
-
-A VNF module may support nested templates. In this case, there will be
-one or more additional YAML files.
-
-Any shared resource defined in the base module template and used across
-the entire VNF (e.g., private networks, server groups), must be exposed
-to the incremental or add-on modules by declaring their resource UUIDs
-as Heat outputs (i.e., OpenECOMP Base Template Output Parameter in the
-output section of the Heat template). Those outputs will be provided by
-OpenECOMP as input parameter values to all add-on module Heat templates
-in the VNF that have declared the parameter in the template.
-
-*Note:* A Cinder volume is *not* considered a shared resource. A volume
-template must correspond 1:1 with a base template or add-on module
-template.
-
-There are two suggested usage patterns for modular VNFs, though any
-variation is supported.
-
-A. **Modules per VNFC type**
-
- a. Group all VMs (VNFCs) of a given type into its own module
-
- b. Build up the VNF one VNFC type at a time
-
- c. Base module contains only the shared resources (and possibly
- initial Admin VMs)
-
- d. Suggest one or two modules per VNFC type
-
- i. one for initial count
-
- ii. one for scaling increment (if different from initial count)
-
-B. **Base VNF + Growth Units**
-
- a. Base module (template) contains a complete initial VNF instance
-
- b. Growth modules for incremental scaling units
-
- i. May contain VMs of multiple types in logical scaling
- combinations
-
- ii. May be separated by VM type for multi-dimensional scaling
-
- c. With no growth units, this is equivalent to the “\ *One Heat
- Template per VNF*\ ” model
-
-Note that modularization of VNFs is not required. A single Heat template
-(a base template) may still define a complete VNF, which might be
-appropriate for smaller VNFs without a lot of scaling options.
-
-There are some rules to follow when building modular VNF templates:
-
-1. All VNFs must have one Base VNF Module (template) that must be the
- first one deployed. The base template:
-
- a. Must include all shared resources (e.g., private networks, server
- groups, security groups)
-
- b. Must expose all shared resources (by UUID) as “outputs” in its
- associated Heat template (i.e., OpenECOMP Base Template Output
- Parameters)
-
- c. May include initial set of VMs
-
- d. May be operational as a stand-alone “minimum” configuration of the
- VNF
-
-2. VNFs may have one or more Add-On VNF Modules (templates) which:
-
- a. Defines additional resources that can be added to an existing VNF
-
- b. Must be complete Heat templates
-
- i. i.e. not snippets to be incorporated into some larger template
-
- c. Should define logical growth-units or sub-components of an overall
- VNF
-
- d. On creation, receives all Base VNF Module outputs as parameters
-
- i. Provides access to all shared resources (by UUID)
-
- ii. must not be dependent on other Add-On VNF Modules
-
- e. Multiple instances of an Add-On VNF Module type may be added to
- the same VNF (e.g. incrementally grow a VNF by a fixed “add-on”
- growth units)
-
-3. Each VNF Module (base or add-on) may have (optional) an associated
- Volume template (*see Section 2.5*)
-
- a. Volume templates should correspond 1:1 with Module (base or
- add-on) templates
-
- b. A Cinder volume may be embedded within the Module template (base
- or add-on) if persistence is not required
-
-4. Shared resource UUIDs are passed between the base template and add-on
- template via Heat Outputs Parameters (i.e., Base Template Output
- Parameters)
-
- a. The output parameter name in the base must match the parameter
- name in the add-on module
-
-*Examples:*
-
-In this example, the {vm-type} have been defined as “lb” for load
-balancer and “admin” for admin server.

-Scaling Considerations
-======================
-
-Scaling of a VNF may be manually driven to add new capacity (**static
-scaling**) or it may be driven in near real-time by the OpenECOMP
-controllers based on a real-time need **(dynamic scaling).**
-
-With VNF Modularity, the recommended approach for scaling is to provide
-additional “growth unit” templates that can be used to create additional
-resources in logical scaling increments. This approach is very
-straightforward, and has minimal impact on the currently running VNFCs
-and must comply with the following:
-
-- Combine resources into reasonable-sized scaling increments; do not
- just scale by one VM at a time in potentially large VNFs.
-
-- Combine related resources into the same growth template where
- appropriate, e.g. if VMs of different types are always deployed in
- pairs, include them in a single growth template.
-
-- Growth templates can use the private networks and other shared
- resources exposed by the Base Module template.
-
-VNF Modules may also be updated “in-place” using the OpenStack Heat
-Update capability, by deploying an updated Heat template with different
-VM counts to an existing stack. This method requires another VNF module
-template that includes the new resources *in addition to all resources
-contained in the original module template*. Note that this also requires
-re-specification of all existing parameters as well as new ones.
-
-*For this approach:*
-
-- Use a fixed number of pre-defined VNF module configurations
-
-- Successively larger templates must be identical to the next smaller
- one, plus add the additional VMs of the scalable type(s)
-
-- VNF is scalable by sending a stack-update with a different template
-
-*Please do note that:*
-
-- If properties do not change for existing VMs, those VMs should remain
- unchanged
-
-- If the update is performed with a smaller template, the Heat engine
- recognizes and deletes no-longer-needed VMs (and associated
- resources)
-
-- Nested templates for the various server types will simplify reuse
- across multiple configurations
-
-- Per the section on Use of Heat ResourceGroup, if *ResourceGroup* is
- ever used for scaling (e.g. increment the count and include an
- additional element to each list parameter), Heat will often rebuild
- every existing element in addition to adding the “deltas”.  For this
- reason, use of *ResourceGroup* for scaling in this manner is not
- supported.
-
-High Availability
-==================
-
-VNF/VM parameters may include availability zone IDs for VNFs that
-require high availability.
-
-The Heat must comply with the following requirements to specific
-availability zone IDs:
-
-- The Heat template should spread Nova and Cinder resources across the
- availability zones as desired
-
-Resource Data Synchronization
-==============================
-
-For cases where synchronization is required in the orchestration of Heat
-resources, two approaches are recommended:

-- Standard Heat *“depends\_on”* property for resources
-
- - Assures that one resource completes before the dependent resource
- is orchestrated.
-
- - Definition of completeness to OpenStack may not be sufficient
- (e.g., a VM is considered complete by OpenStack when it is ready
- to be booted, not when the application is up and running).

-- Use of Heat Notifications
-
- - Create *OS::Heat::WaitCondition* and
- *OS::Heat::WaitConditionHandle* resources.
-
- - Pre-requisite resources issue *wc\_notify* commands in user\_data.
-
- - Dependent resource define *“depends\_on”* in the
- *OS::Heat::WaitCondition* resource.
-
-*Example: “depends\_on” case*
-
-In this example, the {network-role} has been defined as “oam” to
-represent an oam network and the {vm-type} has been defined as “oam” to
-represent an oam server.

-Appendix A - Glossary
-======================
-
-**VM** Virtual Machine (VM) is a virtualized computation environment
-that behaves very much like a physical computer/server. A VM has all its
-ingredients (processor, memory/storage, interfaces/ports) of a physical
-computer/server and is generated by a hypervisor, which partitions the
-underlying physical resources and allocates them to VMs. Virtual
-Machines are capable of hosting a virtual network function component
-(VNFC).
-
-**VNF** Virtual Network Function (VNF) is the software implementation of
-a function that can be deployed on a Network Cloud. It includes network
-functions that provide transport and forwarding. It also includes other
-functions when used to support network services, such as
-network-supporting web servers and database.
-
-**VNFC** Virtual Network Function Component (VNFC) are the
-sub-components of a VNF providing a VNF Provider a defined sub-set of
-that VNF's functionality, with the main characteristic that a single
-instance of this component maps 1:1 against a single Virtualization
-Container. See **Figure 1** for the relationship between VNFC and
-VNFs.

-Document summary:
-
-*VNF Guidelines for Network Cloud and OpenECOMP*
-
-- Describes VNF environment and overview of requirements
-
-*VNF Cloud Readiness Requirements for OpenECOMP*
-
-- Cloud readiness requirements for VNFs (Design, Resiliency, Security,
- and DevOps)
-
-**VNF Management Requirements for OpenECOMP**
-
-- Requirements for how VNFs interact and utilize OpenECOMP
-
-*VNF Heat Template Requirements for OpenECOMP*
-
-- Provides recommendations and standards for building Heat templates
- compatible with OpenECOMP– initial implementations of Network Cloud
- are assumed to be OpenStack based.
-
-The OpenECOMP (Enhanced Control, Orchestration, Management and Policy)
-platform is the part of the larger Network Function
-Virtualization/Software Defined Network (NFV/SDN) ecosystem that is
-responsible for the efficient control, operation and management of
-Virtual Network Function (VNF) capabilities and functions. It specifies
-standardized abstractions and interfaces that enable efficient
-interoperation of the NVF/SDN ecosystem components. It enables
-product/service independent capabilities for design, creation and
-runtime lifecycle management (includes all aspects of installation,
-change management, assurance, and retirement) of resources in NFV/SDN
-environment (see `ECOMP white paper <http://att.com/ecomp>`__\ [1]_).
-These capabilities are provided using two major architectural
-frameworks: (1) a Design Time Framework to design, define and program
-the platform (uniform onboarding), and (2) a Runtime Execution Framework
-to execute the logic programmed in the design environment (uniform
-delivery and runtime lifecycle management). The platform delivers an
-integrated information model based on the VNF package to express the
-characteristics and behavior of these resources in the Design Time
-Framework. The information model is utilized by Runtime Execution
-Framework to manage the runtime lifecycle of the VNFs. The management
-processes are orchestrated across various modules of OpenECOMP to
-instantiate, configure, scale, monitor, and reconfigure the VNFs using a
-set of standard APIs provided by the VNF developers.
-
-Design Definition
-=================
-
-The OpenECOMP Design Time Framework provides the ability to design NFV
-resources including VNFs, Services, and products. The vendor must
-provide VNF packages that include a rich set of recipes, management and
-functional interfaces, policies, configuration parameters, and
-infrastructure requirements that can be utilized by the OpenECOMP Design
-module to onboard and catalog these resources. Initially this
-information may be provided in documents, but in the near future a
-method will be developed to automate as much of the transfer of data as
-possible to satisfy its long term requirements.
-
-The current VNF Package Requirement is based on a subset of the
-Requirements contained in the ETSI Document: ETSI GS NFV-MAN 001 v1.1.1
-and GS NFV IFA011 V0.3.0 (2015-10) - Network Functions Virtualization
-(NFV), Management and Orchestration, VNF Packaging Specification.

-Configuration Management
-========================
-
-OpenECOMP interacts directly with VNFs through its Network and
-Application Adapters to perform configuration activities within NFV
-environment. These activities include service and resource
-configuration/reconfiguration, automated scaling of resources, service
-and resource removal to support runtime lifecycle management of VNFs and
-services. The Adapters employ a model driven approach along with
-standardized APIs provided by the VNF developers to configure resources
-and manage their runtime lifecycle.
-
-NETCONF Standards and Capabilities
-----------------------------------
-
-OpenECOMP Controllers and their Adapters utilize device YANG model and
-NETCONF APIs to make the required changes in the VNF state and
-configuration. The VNF providers must provide the Device YANG model and
-NETCONF server supporting NETCONF APIs to comply with target OpenECOMP
-and industry standards.

-+-----------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | Locking is required if a common object is being manipulated by two simultaneous NETCONF configuration operations on the same VNF within the context of the same writable running data store (e.g., if an interface parameter is being configured then it should be locked out for configuration by a simultaneous configuration operation on that same interface parameter). | Must | 11210 |
-+-----------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | Locking must be applied based on the sequence of NETCONF operations, with the first configuration operation locking out all others until completed. | Must | 11220 |
-+-----------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | If a VNF needs to lock an object for configuration, the lock must be permitted at the finest granularity to avoid blocking simultaneous configuration operations on unrelated objects (e.g., BGP configuration should not be locked out if an interface is being configured, Entire Interface configuration should not be locked out if a non-overlapping parameter on the interface is being configured). The granularity of the lock must be able to be specified via a restricted or full XPath expression. | Must | 11230 |
-+-----------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | All simultaneous configuration operations should guarantee the VNF configuration integrity (for example: if a change is attempted to the BUM filter rate from multiple interfaces on the same EVC, then they need to be sequenced in the VNF without locking either configuration method out) | Must | 11240 |
-+-----------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | To prevent permanent lock-outs, locks must be released: | Must | 11250 |
-| | | | |
-| | a. when/if a session applying the lock is terminated (e.g., SSH session is terminated) | | |
-| | | | |
-| | b. the corresponding <partial-unlock> operation succeeds | | |
-| | | | |
-| | c. a user configured timer has expired forcing the NETCONF SSH Session termination (i.e., product must expose a configuration knob for a user setting of a lock expiration timer) | | |
-| | | | |
-| | Additionally, to guard against hung NETCONF sessions, another NETCONF session should be able to initiate the release of the lock by killing the session owning the lock, using the <kill-session> operation. | | |
-+-----------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | The VNF should support simultaneous <commit> operations within the context of this locking requirements framework. | Must | 11260 |

-VNF REST APIs
---------------
-
-Healthcheck is a command for which no NETCONF support exists. Therefore,
-this must be supported using a RESTful interface which we have defined.
-
-The VNF must provide two REST formatted RPCs to support Healthcheck
-queries via the GET method over HTTP(s).
-
-**Table 5. VNF REST APIs**
-
-+-----------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| **Principal** | **Description** | **Type** | **ID #** |
-+=================+================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================+============+============+
-| 3.2.1 | **GET /check** - The **/check** RPC, executes a vendor-defined VNF Healthcheck over the scope of the entire VNF (e.g if there are multiple VMs, then run a health check, as appropriate, for all VMs). /check returns a 200 OK if the test passes and a 50x response if the test fails. The precise failure code may depend upon type of failure (process error, overload etc.). A JSON object is returned indicating state, scope identifier, time-stamp and info field as well as an optional fault field. | Must | 12190 |
-| | | | |
-| REST APIs | For example: | | |
-| | | | |
-| | 503 Threshold Exceeded | | |
-| | | | |
-| | { | | |
-| | | | |
-| | "identifier": "scope represented", | | |

-| | | | |
-| | } | | |
-+-----------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | **GET /status** - The **/status** RPC returns a 200 OK code and state of the VNF (resources utilized) in the form of a nested JSON response (multiple resources for each VM within the VNF). | Must | 12200 |
-| | | | |
-| | For example: | | |
-| | | | |
-| | { | | |
-| | | | |

-OpenECOMP Controller APIs and Behavior
---------------------------------------
-
-OpenECOMP Controllers support the following operations which act
-directly upon the VNF. Most of these utilize the NETCONF interface.
-There are additional commands in use but these either act internally on
-Controller itself or depend upon network cloud components for
-implementation. Those actions do not put any special requirement on the
-VNF provider.
-
-The following table summarizes how the VNF must act in response to
-commands from OpenECOMP.
-
-Table 6. OpenECOMP Controller APIs
-
-+---------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------------------------+

-| Action | Queries OpenECOMP Controller for the current state of a previously submitted runtime LCM (Lifecycle Management) action. | Checks if VNF is busy. Current operation depends on a completion code from any previous operation. In the future a positive acknowledgement of busy status may be useful to handle ambiguous conditions. However, at this time none is being used. | <none> |
-| | | | |
-| Status | | | |
-+---------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------------------------+
-| Audit | Compare active configuration against a configuration stored in OpenECOMP’s configuration store. | Retrieve running configuration and device state information. Get-config updates the config tree which can then be compared to the stored current config in the OpenECOMP database. | get-config |
-+---------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------------------------+
-| Check | Returns true when the given VNF has been locked. | VnfLock may have been used to lock the VNF. There is currently no way to query lock state in NETCONF so locked state is managed internally by OpenECOMP. | <none> |
-| | | | |
-| Lock | | | |
-+---------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------------------------+
-| Configure | Configures the target VNF or VNFC. | The <edit-config> operation loads all or part of a specified configuration data set to the specified target VNF. | edit-config, commit |
-+---------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------------------------+
-| Health | Executes a VNF health check and returns the result. A health check is VNF-specific. | The OpenECOMP health check interface is defined over REST and requires the target VNF to expose a standardized HTTP(S) interface for that purpose. Return the health status of the VNF by performing (via any vendor-specific means) internal checks of needed resources, process states, etc. The specific errors returned can be used to indicate the source of the problem. OpenECOMP will generate error events for all reported health problems. | **REST API** |
-| | | | |
-| Check | | | GET /check |
-| | | | |
-| | | | GET /status |
-+---------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------------------------+
-| Live | Upgrades the target VNF to a new version without interrupting VNF operation. | Supported today on some VNFs via CLI only (the CLI use is an interim solution) | load, restart |
-| | | | |
-| Upgrade | | | |

-| <mount> | This is an internal Controller operation used to create config-tree and operations tree in the controller. | OpenECOMP must retrieve a schema definition from the VNF. The NETCONF server returns the requested schema. During session establishment OpenECOMP issues a NETCONF <get> command which will retrieve all running configuration parameters, all running operational parameters and a list of NETCONF schemas. OpenECOMP retrieves the schemas to create a Yang model describing the parameters used by the VNF and legal values for each parameter (patterns or ranges). The schemas tell OpenECOMP what parameters can be set and what constitute legal values for those parameters. | get, get-schema |
-+---------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------------------------+
-| Config | The ConfigModify LCM action affects only a subset of the total configuration data of a VNF. It can be used to change specific parameters across a number of separate instances for the same VnfcType without changing instance specific values of each. It can also be used to make successive changes to a number of parameters where those changes are considered cumulative. Thus each ConfigModify invocation leaves previous values untouched and only edits the parameters which are sent to OpenECOMP. | The <edit-config> operation loads only a part of the full set of configuration parameters to the specified target configuration without changing any existing parameters. | edit-config, commit |
-| | | | |
-| Modify | | | |
-+---------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------------------------+
-| Config | Saves a VNF’s running configuration into the configuration store in OpenECOMP, for later retrieval. | (optional) If copy-config to a local file is supported by the VNFC this command is used to store the running config locally in order to save time on any subsequent Reconfigure. To support this action, the VNF must allow <copy-config> to save to a local file and must support subsequent retrieval of the copied configuration back to the running configuration. If this capability is not supported, OpenECOMP will still function, but updates will take longer. | copy-config, delete-config |
-| | | | |
-| Save | | | |
-+---------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------------------------+
-| Reconfigure | Reconfigure a VNF to some previously stored baseline configuration stored by a previous ConfigSetBaseline. | If a previous config has been saved locally, and designated as the baseline configuration, use quick restore (<copy-config> from file). If the restore fails, fallback to a process of changing the configuration value by value using <edit-config> and referencing the SQL values stored by APP-C. | edit-config or copy-config |

-the VNFs’ APIs. These can be in the form of Asynchronous interfaces for
-event, fault notifications, and autonomous data streams. They can also
-be Synchronous interfaces for on-demand requests to retrieve various
-performance, usage, and other event information.
-
-The target direction for VNF interfaces is to employ APIs that are
-implemented utilizing standardized messaging and modeling protocols over
-standardized transports. Migrating to a virtualized environment presents
-a tremendous opportunity to eliminate the need for proprietary
-interfaces for vendor equipment while removing the traditional
-boundaries between Network Management Systems and Element Management
-Systems. Additionally, VNFs provide the ability to instrument the
-networking applications by creating event records to test and monitor
-end-to-end data flow through the network, similar to what physical or
-virtual probes provide without the need to insert probes at various
-points in the network. The VNF vendors must be able to provide the
-aforementioned set of required data directly to the OpenECOMP collection
-layer using standardized interfaces.
-
-Transports and Protocols Supporting Resource Interfaces
--------------------------------------------------------
-
-Delivery of data from VNFs to OpenECOMP must use the same common
-transport mechanisms and protocols for all VNFs. Transport mechanisms
-and protocols have been selected to enable both high volume and moderate
-volume datasets, as well as asynchronous and synchronous communications
-over secure connections. The specified encoding provides
-self-documenting content, so data fields can be changed as needs evolve,
-while minimizing changes to data delivery.
-
-The term ‘Event Record’ is used throughout this document to represent
-various forms instrumentation/telemetry made available by the VNF
-including, faults, status events and various other types of VNF
-measurements and logs. Headers received by themselves must be used as
-heartbeat indicators. The common structure and delivery protocols for
-other types of data will be given in future versions of this document as
-we get more insight into data volumes and required processing.
-
-In the following guidelines we provide options for encoding,
-serialization and data delivery. Agreements between Service Providers
-and VNF vendors shall determine which encoding, serialization and
-delivery method to use for particular data sets. The selected methods
-must be agreed to prior to the on-boarding of the VNF into OpenECOMP
-design studio.

-| **Principle** | **Description** | **Type** | **ID #** |
-+==============================================+=====================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================+============+============+
-| 4.1.1 | Content delivered from VNFs to OpenECOMP is to be encoded and serialized using JSON (option 1). High-volume data is to be encoded and serialized using Avro, where Avro data format are described using JSON (option 2) [3]_. | Must | 13010 |
-| | | | |
-| Encoding and Serialization | - JSON plain text format is preferred for moderate volume data sets (option 1), as JSON has the advantage of having well-understood simple processing and being human-readable without additional decoding. Examples of moderate volume data sets include the fault alarms and performance alerts, heartbeat messages, measurements used for VNF scaling and syslogs. | | |
-| | | | |
-| | - Binary format using Avro is preferred for high volume data sets (option 2) such as mobility flow measurements and other high-volume streaming events (such as mobility signaling events or SIP signaling) or bulk data, as this will significantly reduce the volume of data to be transmitted. As of the date of this document, all events are reported using plain text JSON and REST. | | |
-| | | | |
-| | - Avro content is self-documented, using a JSON schema. The JSON schema is delivered along with the data content (http://avro.apache.org/docs/current/ ). This means the presence and position of data fields can be recognized automatically, as well as the data format, definition and other attributes. Avro content can be serialized as JSON tagged text or as binary. In binary format, the JSON schema is included as a separate data block, so the content is not tagged, further compressing the volume. For streaming data, Avro will read the schema when the stream is established and apply the schema to the received content. | | |
-| | | | |
-| | - In the future, we may consider support for other types of encoding & serialization (e.g., gRPC) based on industry demand. | | |
-+----------------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| 4.1.2 | The frequency that asynchronous data is delivered will vary based on the content and how data may be aggregated or grouped together. For example, alarms and alerts are expected to be delivered as soon as they appear. In contrast, other content, such as performance measurements, KPIs or reported network signaling may have various ways of packaging and delivering content. Some content should be streamed immediately; or content may be monitored over a time interval, then packaged as collection of records and delivered as block; or data may be collected until a package of a certain size has been collected; or content may be summarized statistically over a time interval, or computed as a KPI, with the summary or KPI being delivered. | Must | 13020 |
-| | | | |
-| Reporting Frequency | - We expect the reporting frequency to be configurable depending on the virtual network function’s needs for management. For example, Service Provider may choose to vary the frequency of collection between normal and trouble-shooting scenarios. | | |
-| | | | |
-| | - Decisions about the frequency of data reporting will affect the size of delivered data sets, recommended delivery method, and how the data will be interpreted by OpenECOMP. However, this should not affect deserialization and decoding of the data, which will be guided by the accompanying JSON schema. | | |
-+----------------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| 4.1.3 | OpenECOMP destinations can be addressed by URLs for RESTful data PUT. Future data sets may also be addressed by host name and port number for TCP streaming, or by host name and landing zone directory for SFTP transfer of bulk files. | Must | 13030 |
-| | | | |
-| Addressing and Delivery Protocol | - REST using HTTPS delivery of plain text JSON is preferred for moderate sized asynchronous data sets, and for high volume data sets when feasible.  | | |
-| | | | |
-| | - VNFs must have the capability of maintaining a primary and backup DNS name (URL) for connecting to OpenECOMP collectors, with the ability to switch between addresses based on conditions defined by policy such as time-outs, and buffering to store messages until they can be delivered. At its discretion, the service provider may choose to populate only one collector address for a VNF. In this case, the network will promptly resolve connectivity problems caused by a collector or network failure transparently to the VNF. | | |
-| | | | |
-| | - VNFs will be configured with initial address(es) to use at deployment time. After that the address(es) may be changed through OpenECOMP-defined policies delivered from OpenECOMP to the VNF using PUTs to a RESTful API, in the same way that other controls over data reporting will be controlled by policy. | | |
-| | | | |
-| | - Other options are expected to include: | | |
-| | | | |
-| | - REST delivery of binary encoded data sets. | | |
-| | | | |
-| | - TCP for high volume streaming asynchronous data sets and for other high volume data sets. TCP delivery can be used for either JSON or binary encoded data sets. | | |
-| | | | |
-| | - SFTP for asynchronous bulk files, such as bulk files that contain large volumes of data collected over a long time interval or data collected across many VNFs. This is not preferred. Preferred is to reorganize the data into more frequent or more focused data sets, and deliver these by REST or TCP as appropriate. | | |
-| | | | |
-| | - REST for synchronous data, using RESTCONF (e.g., for VNF state polling). | | |
-| | | | |
-| | - The OpenECOMP addresses as data destinations for each VNF must be provided by OpenECOMP Policy, and may be changed by Policy while the VNF is in operation. We expect the VNF to be capable of redirecting traffic to changed destinations with no loss of data, for example from one REST URL to another, or from one TCP host and port to another. | | |

-Data Model for Event Records
------------------------------
-
-This section describes the data model for the collection of telemetry
-data from VNFs by Service Providers (SPs) to manage VNF health and
-runtime lifecycle. This data model is referred to as the VNF Event
-Streaming (VES) specifications. OPNFV has a VES project [4]_ that
-provides a holistic solution for OpenStack’s internal telemetry to
-manage Application (VNFs), Physical and virtual infrastructure (compute,
-storage, network devices), and virtual infrastructure managers (cloud
-controllers, SDN controllers). Note that any configurable parameters for
-these data records (e.g., frequency, granularity, policy-based
-configuration) will be managed using the “Configuration” framework
-described in the prior sections.
-
-The Data Model consists of:
-
-- Common Header Record: This precedes each of the domain-specific
- records.
-
-- Domain Specific Event Records. This version of the document specifies
- the model for Fault, Performance, Syslog, State Change, and Mobile
- Flow records. In the future, these will be extended to support other
- types of records (e.g., Signaling or control plane messages,
- probe-less monitoring records, Status Records, Security records,
- etc.). Each of these records allows additional fields (name value
- pairs) for extensibility. The VNF vendors can use these VNF-specific
- additional fields to provide additional information that may be
- relevant to the managing systems.
-

-
-Event Records - Data Structure Description
-------------------------------------------
-
-The data structure for event records consists of a Header Block and zero
-(heartbeat would only have header) or more event domain blocks (e.g.,
-Common Fault Event domain, Common Performance Event domain, Common
-Syslog Event domain, Specialized Mobile Flow Event Domain, etc.). The
-tables in Appendix A present the details for the Common Header and other
-specific record types.
-
-Common Event Header
-~~~~~~~~~~~~~~~~~~~
-
-The common header that precedes any of the domain-specific records
-contains information identifying the type of record to follow,
-information about the sender and other identifying characteristics
-related to timestamp, sequence number, etc. The table A.1 in Appendix A
-describes the structure for the common header.
-
-Event Data Structure – Fault Fields
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The Fault Record, describing a condition in the Fault domain, contains
-information about the fault such as the entity under fault, the
-severity, resulting status, etc. The table A.2 in Appendix A describes
-the structure for the fault record.
-
-Event Data Structure – Measurements for VNF Scaling Fields
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The VNF Scaling Record contains information about VNF resource structure
-and its condition to help in the management of the resources for
-purposes of elastic scaling. The table A.3 in Appendix A describes the
-structure for the VNF Scaling record.
-
-Event Data Structure – Syslog Fields
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The Syslog Record provides a structure for communicating any type of
-information that may be logged by the VNF. It can contain information
-about system internal events, status, errors, etc. The table A.4 in
-Appendix A describes the structure for the Syslog record.
-
-Event Data Structure – State Change Fields
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The State change domain provides a structure for communicating
-information about data flow through the VNF. It can contain information
-about state change related to Physical device that is reported by VNF.
-As an example when cards or port name of the entity that has changed
-state. The table A.5 in Appendix A describes the structure of the State
-Change record.
-
-Event Data Structure – Mobile Flow Fields
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The Mobile Flow Record provides a structure for communicating
-information about data flow through the VNF. It can contain information
-about connectivity and data flows between serving elements for mobile
-service, such as between LTE reference points, etc. The table A.6 in
-Appendix A describes the structure for the Mobile Flow record.
-
-Appendix A – Data Record Format
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The following provides additional information on the event record
-formats for the following data structures (for complete information,

-This reference document lists the requirements that are the supporting
-details for the Virtual Network Function (VNF) characteristics outlined
-in the *VNF Guidelines for Network Cloud and ONAP*. These requirements
-are grouped into the following categories: VNF Design, Resiliency,
-Security, and DevOps. Specific requirements for ONAP can be found in the
-*VNF Management Requirements for ONAP* reference document.
-
-This section outlines the guidelines for VNFs to be compliant with
-running on a multi-tenant, Network Cloud infrastructure. VNFs must be
-virtualized, software-based, execute in a multi-tenant cloud, and be
-de-coupled from the cloud hardware. To achieve interoperability between
-VNFs, open and standard interfaces and APIs must be used. The set of
-reusable VNFs forms the basis of a VNF catalog that is made available to
-service designers to compose new (service chained) services that can
-include service-specific custom parameters and QoS policies. Use of open
-source technologies to leverage industry innovation is important in the
-design of virtualized services. Equally important is the re-use of
-common technologies (e.g., virtualized load balancers, firewalls, etc.)
-that are provided by the platform.
-
-VNF Design
-==========
-
-Services are composed of VNFs and common components and are designed to
-be agnostic of the location to leverage capacity where it exists in the
-Network Cloud. VNFs can be instantiated in any location that meets the
-performance and latency requirements of the service.
-
-A key design principle for virtualizing services is decomposition of
-network functions using NFV concepts into granular VNFs. This enables
-instantiating and customizing only essential functions as needed for the
-service, thereby making service delivery more nimble. It provides
-flexibility of sizing and scaling and also provides flexibility with
-packaging and deploying VNFs as needed for the service. It enables
-grouping functions in a common cloud data center to minimize
-inter-component latency. The VNFs should be designed with a goal of
-being modular and reusable to enable using best-in-breed vendors
-
-Section 4.1.1 in *VNF Guidelines for Network Cloud and ONAP* describes
-the overall guidelines for designing VNFs from VNF Components (VNFCs).
-Below are more detailed requirements for composing VNFs.

-
-Resiliency
-==========
-
-The VNF is responsible for meeting its resiliency goals and must factor
-in expected availability of the targeted virtualization environment.
-This is likely to be much lower than found in a traditional data center.
-Resiliency is defined as the ability of the VNF to respond to error
-conditions and continue to provide the service intended. A number of
-software resiliency dimensions have been identified as areas that should
-be addressed to increase resiliency. As VNFs are deployed into the
-Network Cloud, resiliency must be designed into the VNF software to
-provide high availability versus relying on the Network Cloud to achieve
-that end.
-
-Section 4.1.2 in *VNF Guidelines for Network Cloud and ONAP* describes
-the overall guidelines for designing VNFs to meet resiliency goals.
-Below are more detailed resiliency requirements for VNFs.
-
-All Layer Redundancy
---------------------
-
-Design the VNF to be resilient to the failures of the underlying
-virtualized infrastructure (Network Cloud). VNF design considerations
-would include techniques such as multiple vLANs, multiple local and
-geographic instances, multiple local and geographic data replication,
-and virtualized services such as Load Balancers.
-
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| All Layer Redundancy Requirements | Type | ID # |
-+=======================================================================================================================================================================================================================================================================================================+========+=========+
-| VNFs are responsible to meet their own resiliency goals and not rely on the Network Cloud. | Must | 30010 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Design resiliency into a VNF such that the resiliency deployment model (e.g., active-active) can be chosen at run-time. | Must | 30020 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| VNFs must survive any single points of failure within the Network Cloud (e.g., virtual NIC, VM, disk failure). | Must | 30030 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| VNFs must survive any single points of software failure internal to the VNF (e.g., in memory structures, JMS message queues). | Must | 30040 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Design, build and package VNFs to enable deployment across multiple fault zones (e.g., VNFCs deployed in different servers, racks, OpenStack regions, geographies) so that in the event of a planned/unplanned downtime of a fault zone, the overall operation/throughput of the VNF is maintained. | Must | 30050 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Support the ability to failover a VNFC automatically to other geographically redundant sites if not deployed active-active to increase the overall resiliency of the VNF. | Must | 30060 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Support the ability of the VNFC to be deployable in multi-zoned cloud sites to allow for site support in the event of cloud zone failure or upgrades. | Must | 30070 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-
-Minimize Cross Data-Center Traffic
-----------------------------------
-
-Avoid performance-sapping data center-to-data center replication delay
-by applying techniques such as caching and persistent transaction paths
-- Eliminate replication delay impact between data centers by using a
-concept of stickiness (i.e., once a client is routed to data center "A",
-the client will stay with Data center “A” until the entire session is
-completed).
-
-+------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Minimize Cross Data-Center Traffic Requirements | Type | ID # |
-+==================================================================================================================+==========+=========+
-| Minimize the propagation of state information across multiple data centers to avoid cross data center traffic. | Should | 31010 |
-+------------------------------------------------------------------------------------------------------------------+----------+---------+
-
-Application Resilient Error Handling
-------------------------------------
-
-Ensure an application communicating with a downstream peer is equipped
-to intelligently handle all error conditions. Make sure code can handle
-exceptions seamlessly - implement smart retry logic and implement
-multi-point entry (multiple data centers) for back-end system
-applications.
-
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Application Resilient Error Handling Requirements | Type | ID # |
-+==============================================================================================================================================================================================================================================================================================================================+========+=========+

-| Handle the start or restart of VNFC instances in any order with each VNFC instance establishing or re-establishing required connections or relationships with other VNFC instances and/or VNFs required to perform the VNF function/role without requiring VNFC instance(s) to be started/restarted in a particular order. | Must | 32030 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Handle errors and exceptions so that they do not interrupt processing of incoming VNF requests to maintain service continuity. | Must | 32040 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Provide the ability to modify the number of retries, the time between retries and the behavior/action taken after the retries have been exhausted for exception handling to allow the NCSP to control that behavior. | Must | 32050 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Fully exploit exception handling to the extent that resources (e.g., threads and memory) are released when no longer needed regardless of programming language. | Must | 32060 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Handle replication race conditions both locally and geo-located in the event of a data base instance failure to maintain service continuity. | Must | 32070 |

-| Automatically retry/resubmit failed requests made by the software to its downstream system to increase the success rate. | Must | 32080 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-
-System Resource Optimization
-----------------------------
-
-Ensure an application is using appropriate system resources for the task
-at hand; for example, do not use network or IO operations inside
-critical sections, which could end up blocking other threads or
-processes or eating memory if they are unable to complete. Critical
-sections should only contain memory operation, and should not contain
-any network or IO operation.

-| System Resource Optimization Requirements | Type | ID # |
-+=================================================================================================================================================================================================================================================+==========+=========+
-| Do not execute long running tasks (e.g., IO, database, network operations, service calls) in a critical section of code, so as to minimize blocking of other operations and increase concurrent throughput. | Must | 33010 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Automatically advertise newly scaled components so there is no manual intervention required. | Must | 33020 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Utilize FQDNs (and not IP address) for both Service Chaining and scaling. | Must | 33030 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Deliver any and all functionality from any VNFC in the pool. The VNFC pool member should be transparent to the client. Upstream and downstream clients should only recognize the function being performed, not the member performing it. | Must | 33040 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Automatically enable/disable added/removed sub-components or component so there is no manual intervention required. | Should | 33050 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Support the ability to scale down a VNFC pool without jeopardizing active sessions. Ideally, an active session should not be tied to any particular VNFC instance. | Should | 33060 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Support load balancing and discovery mechanisms in resource pools containing VNFC instances. | Should | 33070 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Utilize resource pooling (threads, connections, etc.) within the VNF application so that resources are not being created and destroyed resulting in resource management overhead. | Should | 33080 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Use techniques such as “lazy loading” when initialization includes loading catalogues and/or lists which can grow over time, so that the VNF startup time does not grow at a rate proportional to that of the list. | Should | 33090 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Release and clear all shared assets (memory, database operations, connections, locks, etc.) as soon as possible, especially before long running sync and asynchronous operations, so as to not prevent use of these assets by other entities. | Should | 33100 |
-+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-
-Application Configuration Management
-------------------------------------
-

-to develop gold configurations for technologies like Java, Python, etc.
-
-+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Application Configuration Management Requirements | Type | ID # |
-+===================================================================================================================================================================================+========+=========+
-| Allow configurations and configuration parameters to be managed under version control to ensure consistent configuration deployment, traceability and rollback. | Must | 34010 |
-+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-| Allow configurations and configuration parameters to be managed under version control to ensure the ability to rollback to a known valid configuration. | Must | 34020 |
-+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+

-+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------+---------+
-
-Intelligent Transaction Distribution & Management
--------------------------------------------------
-
-Leverage Intelligent Load Balancing and redundant components (hardware
-and modules) for all transactions, such that at any point in the
-transaction: front end, middleware, back end -- a failure in any one
-component does not result in a failure of the application or system;
-i.e., transactions will continue to flow, albeit at a possibly reduced
-capacity until the failed component restores itself. Create redundancy
-in all layers (software and hardware) at local and remote data centers;
-minimizing interdependencies of components (i.e. data replication,
-deploying non-related elements in the same container).
-
-+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Intelligent Transaction Distribution & Management Requirements | Type | ID # |
-+==================================================================================================================================================================================================================================+==========+=========+
-| Use intelligent routing by having knowledge of multiple downstream/upstream endpoints that are exposed to it, to ensure there is no dependency on external services (such as load balancers) to switch to alternate endpoints. | Should | 35010 |
-+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Use redundant connection pooling to connect to any backend data source that can be switched between pools in an automated/scripted fashion to ensure high availability of the connection to the data source. | Should | 35020 |
-+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Include control loop mechanisms to notify the consumer of the VNF of their exceeding SLA thresholds so the consumer is able to control its load against the VNF. | Should | 35030 |
-+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-
-Deployment Optimization
------------------------
-
-Reduce opportunity for failure, by human or by machine, through smarter
-deployment practices and automation. This can include rolling code
-deployments, additional testing strategies, and smarter deployment
-automation (remove the human from the mix).
-

-+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-
-Monitoring & Dashboard
-----------------------
-
-Promote dashboarding as a tool to monitor and support the general
-operational health of a system. It is critical to the support of the
-implementation of many resiliency patterns essential to the maintenance
-of the system. It can help identify unusual conditions that might
-indicate failure or the potential for failure. This would contribute to
-improve Mean Time to Identify (MTTI), Mean Time to Repair (MTTR), and
-post-incident diagnostics.

-Security
-========
-
-The objective of this section is to provide the key security
-requirements that need to be met by VNFs. The security requirements are
-grouped into five areas as listed below. Other security areas will be
-addressed in future updates. These security requirements are applicable
-to all VNFs. Additional security requirements for specific types of VNFs
-will be applicable and are outside the scope of these general
-requirements.
-
-Section 4.1.3 in *VNF Guidelines for Network Cloud and ONAP* outlines
-the five broad security areas for VNFs that are detailed in the
-following sections:
-
-- **VNF General Security**: This section addresses general security
- requirements for the VNFs that the vendors will need to address.
-
-- **VNF Identity and Access Management**: This section addresses
- security requirements with respect to Identity and Access Management
- as these pertain to generic VNFs.
-
-- **VNF API Security**: This section addresses the generic security
- requirements associated with APIs. These requirements are applicable
- to those VNFs that use standard APIs for communication and data
- exchange.
-
-- **VNF Security Analytics**: This section addresses the security
- requirements associated with analytics for VNFs that deal with
- monitoring, data collection and analysis.
-
-- **VNF Data Protection**: This section addresses the security

-DevOps
-======
-
-This section includes guidelines for vendors to ensure that a Network
-Cloud Service Provider’s operations personnel have a common and
-consistent way to support VNFs and VNFCs.
-
-NCSPs may elect to support standard images to enable compliance with
-security, audit, regulatory and other needs. As part of the overall VNF
-software bundle, VNF suppliers using standard images would typically
-provide the NCSP with an install package consistent with the default OS
-package manager (e.g. aptitude for Ubuntu, yum for Redhat/CentOS).
-
-Section 4.1.4 in *VNF Guidelines for Network Cloud and ONAP* describes
-the DevOps guidelines for VNFs.
-
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| DevOps Requirements | Type | ID # |
-+==============================================================================================================================================================================================================================================================================================================================================================================================================================+==========+=========+
-| Utilize only the Guest OS versions that are supported by the NCSP’s Network Cloud. [2]_ | Must | 50010 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Utilize only NCSP provided Guest OS images.\ :sup:`2` | Should | 50020 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Utilize only NCSP standard compute flavors.\ :sup:`2` | Must | 50030 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Running VMs will not be backed up in the Network Cloud infrastructure. VNF’s are responsible for preserving their persistent data. | Must | 50040 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Install VNFC(s) on non-root file systems, unless software is specifically included with the operating system distribution of the guest image. | Must | 50050 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Be agnostic to the underlying infrastructure (such as hardware, host OS, Hypervisor), any requirements should be provided as specification to be fulfilled by any hardware. | Must | 50060 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Hypervisor-level customization must not be required from the cloud provider. | Must | 50070 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Provide an automated test suite to validate every new version of the software on the target environment(s). The tests should be of sufficient granularity to independently test various representative VNF use cases throughout its lifecycle. Operations might choose to invoke these tests either on a scheduled basis or on demand to support various operations functions including test, turn-up and troubleshooting. | Should | 50080 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| Provide the ability to test incremental growth of the VNF | Should | 50090 |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| If a VNF provides a load balancing function across multiple instances of its VNFCs, then the VNF must respond to a "move traffic"\ :sup:`3` command against a specific VNFC, moving all existing session elsewhere with minimal disruption. | Must | 50100 |
-| | | |
-| Note: Individual VNF performance aspects (e.g., move duration or disruption scope) may require further constraints. | | |
-+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+---------+
-| To support scenarios such as proactive maintenance with no user impact, if a VNF provides a load balancing function across multiple instances of its VNFCs, then the VNF must respond to a "drain VNFC" [3]_ command against a specific VNFC, preventing new session from reaching the targeted VNFC, with no disruption to active sessions on the impacted VNFC. | Must | 50110 |

-Abstract
-========
-
-This white paper and the accompanying reference documents set forth
-guidelines and requirements for Virtual Network Functions (VNFs) that
-run in Network Clouds [1]_ and are managed by ONAP (Open Network
-Automation Platform) [2]_. This document set is part of the ONAP
-community and focuses on setting and evolving VNF standards that will
-facilitate industry discussion, participation, alignment and evolution
-toward comprehensive and actionable VNF best practices and standard
-interfaces. The goal is to accelerate adoption of VNF best practices
-which will increase innovation, minimize customization needed to onboard
-VNFs as well as reduce implementation complexity, time and cost for all
-impacted stakeholders. The intent is to drive harmonization of VNFs
-across VNF providers, Network Cloud Service Providers (NCSPs) and the
-overall Network Function Virtualization (NFV) ecosystem by providing
-both long term vision as well as short term focus and clarity where no
-current open source implementations exist today.
-
-This first release of the guidelines and requirements, although
-applicable in many implementations, is targeted for those
-implementations that consist of Network Clouds based on OpenStack.
-Future versions of these guidelines are envisioned to include other
-targeted virtualization environments, such as Customer Premises or other
-single-tenant small scale cloud implementations.
-
-In addition, given the relative maturity of key technologies involved,
-rapid innovation of NFV/SDN and virtualization technologies as well as
-the evolving ONAP roadmap, this will be a living package that will
-evolve over time. These documents will become part of the ONAP related
-requirements documents. The following enhancements are anticipated to be
-addressed in the next set of releases:
-
-- Open source software and demos of simple reference VNFs;
-
-- Automation of VNF onboarding and other aspects of VNF lifecycle as
- supported by ONAP;
-
-- Consistent VNF packaging for automated onboarding using ONAP;
-
-- Other implementation examples for targeted virtualization
- environments beyond OpenStack based Network Clouds;
-
-- Incubation and certification environment to provide a self-service
- program to gauge maturity and readiness of VNFs.
-
-Introduction
-============
-
-Motivation
-----------
-
-The requirements and guidelines defined herein are intended to
-facilitate industry discussion, participation alignment and evolution
-toward comprehensive and actionable VNF best practices. Integration
-costs are a significant impediment to the development and deployment of
-new services. We envision developing open source industry processes and
-best practices leading eventually to VNF standards supporting commercial
-acquisition of VNFs with minimal integration costs. Traditional PNFs
-have all been unique like snowflakes and required expensive custom
-integration, whereas VNF products and services should be designed for
-easier integration just like Lego\ :sup:`TM` blocks. For example, by
-standardizing on common actions and related APIs supported by VNFs, plug
-and play integration is assured, jumpstarting automation with management
-frameworks. Onboarding VNFs would no longer require complex and
-protracted integration or development activities thus maximizing
-automation and minimizing integration cost. Creating VNF open source
-environments, best practices and standards provides additional benefits
-to the NFV ecosystems such as:
-
-- Larger market for VNF providers
-
-- Rapid introduction and integration of new capabilities into the
- services provider’s environment
-
-- Reduced development times and costs for VNF providers
-
-- Better availability of new capabilities to NCSPs
-
-- Better distribution of new capabilities to end-user consumers
-
-- Reduced integration cost (capex) for NCSPs
-
-- Usage based software licensing for end-user consumers and NCSPs
-
-Audience
----------
-
-The industry transformation associated with softwarization [3]_ results
-in a number of changes in traditional approaches for industry
-collaboration. Changes from hardware to software, from waterfall to
-agile processes and the emergence of industry supported open source
-communities imply corresponding changes in processes at many industry
-collaboration bodies. With limited operational experience and much more
-dynamic requirements, open source communities are expected to evolve
-these VNF guidelines further before final documentation of those aspects
-necessary for standardization. This white paper and accompanying
-reference documents provides VNF providers, NCSPs and other interested
-3rd parties a set of guidelines and requirements for the design, build
-and overall lifecycle management of VNFs.
-
-**VNF Providers**
-
-Both suppliers transitioning from providing physical network functions
-(PNFs) to providing VNFs as well as new market entrants should find
-these VNF requirements and guidelines a useful introduction to the
-requirements to be able to develop VNFs for deployment into a Network
-Cloud. VNF Providers may also be interested to test their VNFs in the
-context of an open source implementation of the environment.
-
-**Network Cloud Service Providers (NCSPs)**
-
-A NCSP provides services based on Network Cloud infrastructure as well
-as services above the infrastructure layer, e.g., platform service,
-end-to-end services.
-
-Common approaches to packaging of VNFs enable economies of scale in
-their development. As suitable infrastructure becomes deployed, NCSPs
-have a common interest in guidelines that support the ease of deployment
-of VNFs in each other’s Network Cloud. After reading these VNF
-guidelines, NCSPs should be motivated to join AT&T in evolving these
-guidelines in the ONAP open source community to meet the industry’s
-collective needs.
-
-**Other interested parties**
-
-Other parties such as solution providers, open source community,
-industry standard bodies, students and researchers of network
-technologies, as well as enterprise customers may also be interested in
-the VNF Guidelines. Solution Providers focused on specific industry
-verticals may find these VNF guidelines useful in the development of
-specialized VNFs that can better address the needs of their industry
-through deployment of these VNFs in NCSP infrastructure. Open Source
-developers can use these VNF guidelines to facilitate the automation of
-VNF ingestion and deployment. The emergence of a market for VNFs enables
-NCSPs to more rapidly deliver increased functionality, for execution on
-white box hardware on customer’s premises – such functionality may be of
-particular interest to enterprises supporting similar infrastructure.

-
-VNF Context
-===========
-
-A technology trend towards softwarization is impacting the
-communications industry as it has already impacted a number of other
-industries. This trend is expected to have some significant impacts on
-the products and processes of this industry. The transformation from
-products primarily based on hardware to products primarily based on
-software has a number of impacts. The completeness of the software
-packages to ease integration, usage based licensing to reflect scaling
-properties, independence from hardware and location and software
-resilience in the presence of underlying hardware failure all gain in
-importance compared to prior solutions. The processes supporting
-software products and services are also expected to transform from
-traditional waterfall methodologies to agile methods. In agile
-processes, characteristics such as versioned APIs, rolling upgrades,
-automated testing and deployment support with incremental release
-schedules become important for these software products and services.
-Industry process related to software products and services also change
-with the rise of industrially supported open source communities.
-Engagement with these open source communities enables sharing of best
-practices and collaborative development of open source testing and
-integration regimes, open source APIs and open source code bases.
-
-The term VNF is inspired by the work [4]_ of the ETSI [5]_ Network
-Functions Virtualization (NFV) Industry Specification Group (ISG).
-ETSI’s VNF definition includes both historically network functions, such
-as Virtual Provider Edge (VPE), Virtual Customer Edge (VCE), and Session
-Border Controller (SBC), as well as historically non-network functions
-when used to support network services, such as network-supporting web
-servers and databases. The VNF discussion in these guidelines applies to
-all types of virtualized workloads, not just network appliance
-workloads. Having a consistent approach to virtualizing any workload
-provides more industry value than just virtualizing some workloads. [6]_
-
-VNFs are functions that are implemented in Network Clouds. Network
-Clouds must support end-to-end high-bandwidth low latency network flows
-through VNFs running in virtualization environments. For example, a
-Network Cloud is able to provide a firewall service to be created such
-that all Internet traffic to a customer premise passes through a virtual
-firewall running in the Network Cloud.
-
-A data center may be the most common target for a virtualization
-environment, but it is not the only target. Virtualization environments
-are also supported by more constrained resources e.g., Enterprise
-Customer Premise Equipment (CPE). Virtualization environments are also
-expected to be available at more distributed network locations by
-architecting central offices as data centers, or virtualizing functions
-located at the edge of the operator infrastructure (e.g., virtualized
-Optical Line Termination (vOLT) or xRAN [7]_) and in constrained
-resource Access Nodes. Expect detailed requirements to evolve with these
-additional virtualization environments. Some VNFs may scale across all
-these environments, but all VNFs should onboard through the same process
-before deployment to the targeted virtualization environment.
-
-Business Process Impacts
--------------------------
-
-Business process changes need to occur in order to realize full benefits
-of VNF characteristics: efficiency via automation, open source reliance,
-and improved cycle time through careful design.
-
-**Efficiency via Automation**
-
-reliant on human labor for critical operational tasks don’t scale. By
-aggressively automating all VNF operational procedures, VNFs have lower
-operational cost, are more rapidly deployed at scale and are more
-consistent in their operation. ONAP provides the automation framework
-which VNFs can take advantage of simply by implementing ONAP compatible
-interfaces and lifecycle models. This enables automation which drives
-operational efficiencies and delivers the corresponding benefits.
-
-**Open Source**
-
-VNFs are expected to run on infrastructure largely enabled by open
-source software. For example, OpenStack [8]_ is often used to provide
-the virtualized compute, network, and storage capabilities used to host
-VNFs. OpenDaylight (ODL) [9]_ can provide the network control plane. The
-OPNFV community [10]_ provides a reference platform through integration
-of ODL, OpenStack and other relevant open source projects. VNFs also run
-in open source operating systems like Linux. VNFs might also utilize
-open source software libraries to take advantage of required common but
-critical software capabilities where community support is available.
-Automation becomes easier, overall costs go down and time to market can
-decrease when VNFs can be developed and tested in an open source
-reference platform environment prior to on-boarding by the NCSP. All of
-these points contribute to a lower cost structure for both VNF providers
-and NCSPs.
-
-**Improved Cycle Time through Careful Design**
-
-Today’s fast paced world requires businesses to evolve rapidly in order
-to stay relevant and competitive. To a large degree VNFs, when used with
-the same control, orchestration, management and policy framework (e.g.,
-ONAP), will improve service development and composition. VNFs should
-enable NCSPs to exploit recursive nesting of VNFs to acquire VNFs at the
-smallest appropriate granularity so that new VNFs and network services
-can be composed. The ETSI NFV Framework [11]_ envisages such recursive
-assembly of VNFs, but many current implementations fail to support such
-features. Designing for VNF reuse often requires that traditional
-appliance based PNFs be refactored into multiple individual VNFs where
-each does one thing particularly well. While the original appliance
-based PNF can be replicated virtually by the right combination and
-organization of lower level VNFs, the real advantage comes in creating
-new services composed of different combinations of lower level VNFs
-(possibly from many providers) organized in new ways. Easier and faster
-service creation often generates real value for businesses. As
-softwarization trends progress towards more agile processes, VNFs, ONAP
-and Network Clouds are all expected to evolve towards continuous
-integration, testing and deployment of small incremental changes to
-de-risk the upgrade process.
-
-ETSI Network Function Virtualization (NFV) comparison
------------------------------------------------------
-
-ETSI defines a VNF as an implementation of a network function that can
-be deployed on a Network Function Virtualization Infrastructure (NFVI).
-Service instances may be composed of an assembly of VNFs. In turn, a VNF
-may also be assembled from VNF components (VNFCs) that each provide a
-reusable set of functionality. VNFs are expected to take advantage of
-platform provided common services.
-
-VNF management and control under ONAP is different than management and
-control exposed in the ETSI MANO model. With ONAP, there is only a
-single management and control plane. In ETSI’s Framework [12]_,
-architectural options exist for preserving legacy systems that increase
-integration costs e.g., different VNFs can be controlled by VNF Managers
-(VNFMs) and Element Management Systems (EMSs) provided by different
-software providers. ONAP addresses the concern that multiple VNFMs in
-this space will hinder VNF reuse and increase VNF and service
-integration costs. Asking all VNF providers to take advantage of and
-interoperate with common control software mitigates related reuse and
-integration challenges. The common, SDN based, control platform (ONAP)
-is being made available as an open source project to reduce friction for
-VNF providers and enable new network functions to get to market faster
-and with lower costs.
-
-Also under ONAP, VNF providers do not provide their own proprietary VNF
-Managers (VNFM) or Element Management Systems (EMS). Those capabilities
-are provided by ONAP. Hence, VNFs are required to consume open
-interfaces to ONAP in support of management and control. The VNF Package
-must include the appropriate data models for integration with ONAP to
-enable management and control of the VNFCs.
-
-**Figure 1** shows a simplified ONAP and Infrastructure view to
-highlight how individual Virtual Network Functions plug into the ONAP
-control loops.
-
-|image0|
-
-**Figure 1. Control Loop**
-
-In the control loop view in **Figure 1**, the VNF provides an event
-data stream via an API to Data Collection, Analytics and Events (DCAE).
-DCAE analyzes and aggregates the data stream and when particular
-conditions are detected, uses policy to enable what, if any, action
-should be triggered. Some of the triggered actions may require a
-controller to make changes to the VNF through a VNF provided API.

-- Comparison between VNF Guidelines and ETSI GS NFV-SWA 001.
-
-Evolving VNF Related Industry Activities
-----------------------------------------
-
-Many existing industry collaboration bodies are structured around a
-particular service or segment of the network. VNFs are intended to
-operate across multiple services and execute on commodity targeted
-virtualization environments. With the NCSPs transformation to acquiring
-products and services based on location and hardware independent VNFs,
-the opportunity exists for instances of those VNFs to be deployed across
-multiple network locations and services where suitable virtualization
-infrastructure is available.
-
-The rise of industry-supported open source communities has created new
-opportunities for collaboration and challenges for existing industry
-communities such as Standards Developing Organizations (SDOs).
-Collaboration in many SDOs defers intellectual property issues. Most
-industrially-supported open source communities resolve intellectual
-property issues between collaborators through explicit contribution
-licensing agreements. Common infrastructure software components (e.g.,
-SDN Controllers, Cloud Management Systems) are expected to be available
-through industrially supported open source communities (e.g., Open
-Daylight and OpenStack). Whether VNFs are open or proprietary, they
-should use open APIs, test and integration capabilities developed in
-industrially supported open source communities (e.g., ONAP, OPNFV).
-
-The migration path for operator’s existing processes and services to
-effectively utilize VNFs may be operator specific. The requirements for
-VNFs may be expected to evolve rapidly as the industry develops
-experience with operational and development best practices for VNFs. In
-particular, industry operations procedures are expected to evolve
-towards agile software methodologies, DevOps, continuous integration and
-continuous deployment (CI/CD). In this environment of changing and
-context-dependent VNF requirements, agile, pragmatic approaches focused
-on delivering functionality in the near term and evolving it towards
-targeted VNF characteristics are preferred over lengthy waterfall
-industry standardization processes. Demonstrating functionality and
-interoperability of appropriate VNF-related APIs in open source
-communities is considered a pre-requisite to starting industry
-specification work documenting stable interfaces.
-
-While multiple open source communities exist supporting particular
-infrastructure software options, the market success of any particular
-option combination cannot be assured. Integration communities such as
-OPNFV provide an approach enabling VNF providers to test their products
-and services against a variety of expected configurations available in
-the industry.
-
-Evolving towards VNFs
----------------------
-
-In order to deploy VNFs, a target virtualization environment must
-already be in place. The NCSPs scale necessitates a phased rollout of
-virtualization infrastructure and then of VNFs upon that infrastructure.
-Some VNF use cases may require greenfield infrastructure deployments,
-others may start brownfield deployments in centralized data centers and
-then scale deployment more widely as infrastructure becomes available.
-Some service providers have been very public and proactive in setting
-transformation targets associated with VNFs [13]_.
-
-Because of the complexity of migration and integration issues, the
-requirements for VNFs in the short term may need to be contextualized to
-the specific service and transition planning.
-
-Much of the existing VNF work has been based on corresponding network
-function definitions and requirements developed for PNFs. Many of the
-assumptions about PNFs do not apply to VNFs and the modularity of the
-functionality is expected to be significantly different. In addition,
-the increased service velocity objectives of NFV are based on new types
-of VNFs being developed to support new services being deployed in
-virtualized environments. Much of the functionality associated with 5G
-(e.g., IoT, augmented reality/virtual reality) is thus expected to be
-deployed as VNFs in targeted virtualization infrastructure towards the
-edge of the network.
-
-VNF Characteristics
-===================
-
-VNFs need to be constructed using a distributed systems architecture
-that we will call "Network Cloud Ready". They need to interact with the
-orchestration and control platform provided by ONAP and address the new
-security challenges that come in this environment.
-
-The main goal of a Network Cloud Ready VNF is to run well on any Network
-Cloud (public or private) over any network (carrier or enterprise). In
-addition, for optimal performance and efficiency, VNFs will be designed
-to take advantage of Network Clouds. This requires careful engineering
-in both VNFs and candidate Network Cloud computing frameworks.
-
-To ensure Network Cloud capabilities are leveraged and VNF resource
-consumption meets engineering and economic targets, VNF performance and
-efficiency will be benchmarked in a controlled lab environment. In line
-with the principles and practices laid out in ETSI GS NFV-PER 001,
-efficiency testing will consist of benchmarking VNF performance with a
-reference workload and associated performance metrics on a reference
-Network Cloud (or, when appropriate, additional benchmarking on a bare
-metal reference platform).
-
-Network Cloud Ready VNF characteristics and design consideration can be
-grouped into three areas:
-
-- Cloud Readiness
-
-- ONAP Ready
-
-- Virtualization Environment Ready
-
-Detailed requirements are contained in the reference documents that are
-listed in Appendix B - References.
-
-Cloud Readiness
----------------
-
-VNFs should be designed to operate within a cloud environment from the
-first stages of the development. The VNF provider should think clearly
-about how the VNF should be decomposed into various modules. Resiliency
-within a cloud environment is very different than in a physical
-environment and the developer should give early thought as to how the
-Network Cloud Service Provider will ensure the level of resiliency
-required by the VNF and then provide the capabilities needed within that
-VNF. Scaling and Security should also be well thought out at design time
-so that the VNF runs well in a virtualized environment. Finally, the VNF
-Provider also needs to think about how they will integrate and deploy
-new versions of the VNF. Since the cloud environment is very dynamic,
-the developer should utilize DevOps practices to deploy new software.
-
-Requirements for Cloud Readiness can be found in the *VNF Common
-Requirements for ONAP* document.
-
-VNF Design
-~~~~~~~~~~
-
-A VNF may be a large construct and therefore when designing it, it is
-important to think about the components from which it will be composed.
-The ETSI SWA 001 document gives a good overview of the architecture of a
-VNF in Chapter 4 as well as some good examples of how to compose a VNF
-in its Annex B. VNFCs are expected to evolve towards microservices, as
-an architectural style so when laying out the components of the VNF it
-is important to keep in mind the following principles: Single
-Capability, Independence, State and the APIs.
-
-Many Network Clouds will use Heat to describe orchestration templates
-for instantiating VNFs and VNFCs. The *VNF Heat Template Requirements
-for ONAP* document defines a modular Heat design pattern referred to as
-“VNF Modularity”. With this approach, a single VNF may be composed from
-one or more Heat Orchestration Templates (modules), each of which
-represents a subset of the overall VNF. A module can be thought of as a
-deployment unit. In general, the goal should be for each module to
-contain a single VNFC.
-
-Single Capability
-^^^^^^^^^^^^^^^^^
-
-VNFs should be carefully decomposed into loosely coupled, granular,
-re-usable VNFCs that can be distributed and scaled on a Network Cloud.
-VNFCs should be responsible for a single capability. The behavior of
-microservice VNFCs is focused on a single capability with independent
-operation and encapsulation
-
-The Network Cloud will define several flavors of VMs for a VNF designer
-to choose from for instantiating a VNFC. The best practice is to keep
-the VNFCs as lightweight as possible while still fulfilling the business
-requirements for the "single capability", however the VNFC should not be
-so small that the overhead of constructing, maintaining, and operating
-the service outweighs its utility.
-
-Independence
-^^^^^^^^^^^^
-
-VNFCs should be independently deployed, configured, upgraded, scaled,
-monitored, and administered (by ONAP). The VNFC must be a standalone
-executable process.
-
-API versioning is one of the biggest enablers of independence. To be
-able to independently evolve a component, versioning must ensure
-existing clients of the component are not forced to flash-cut with each
-interface change. API versioning enables smoother evolution while
-preserving backward compatibility.
-
-Scaling
-^^^^^^^
-
-Each VNFC within a VNF must support independent horizontal scaling, by
-adding/removing instances, in response to demand loads on that VNFC. The
-Network Cloud is not expected to support adding/removing resources
-(compute, memory, storage) to an existing instance of a VNFC (vertical
-scaling). A VNF should be designed such that its components can scale
-independently of each other. Scaling one component should not require
-another component to be scaled at the same time. All scaling will be
-controlled by ONAP.
-
-Managing State
-^^^^^^^^^^^^^^
-
-VNFCs and their interfaces should isolate and manage state to allow for
-high-reliability, scalability, and performance in a Network Cloud
-environment. The use of state should be minimized as much as possible to
-facilitate the movement of traffic from one instance of a VNFC to
-another. Where state is required it should be maintained in a
-geographically redundant data store that may in fact be its own VNFC.
-
-This concept of decoupling state data can be extended to all persistent
-data. Persistent data should be held in a loosely coupled database.
-These decoupled databases need to be engineered and placed correctly to
-still meet all the performance and resiliency requirements of the
-service.
-
-Lightweight and Open APIs
-^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Controllable microservice VNFCs have lightweight communications, are
-discoverable and designed for automation. Key functions are accessible
-via open APIs, which align to Industry API Standards and supported by an
-open and extensible information/data model.
-
-Reusability
-^^^^^^^^^^^
-
-Properly (de)composing a VNF requires thinking about “reusability”.
-Reusable microservice VNFCs are infrastructure agnostic and designed for
-the consumer of their services. Components should be designed to be
-reusable within the VNF as well as by other VNFs. The “single
-capability” principle aids in this requirement. If a VNFC could be
-reusable by other VNFs then it should be designed as its own single
-component VNF that may then be chained with other VNFs. Likewise, a VNF
-provider should make use of other common platform VNFs such as firewalls
-and load balancers, instead of building their own.
-
-Resiliency
-~~~~~~~~~~
-
-The VNF is responsible for meeting its resiliency goals and must factor
-in expected availability of the targeted virtualization environment.
-This is likely to be much lower than found in a traditional data center.
-The VNF developer should design the function in such a way that if there
-is a platform problem the VNF will continue working as needed and meet
-the SLAs of that function. VNFs should be designed to survive single
-failure platform problems including: hypervisor, server, datacenter
-outages, etc. There will also be significant planned downtime for the
-Network Cloud as the infrastructure goes through hardware and software
-upgrades. The VNF should support tools for gracefully meeting the
-service needs such as methods for migrating traffic between instances
-and draining traffic from an instance. The VNF needs to rapidly respond
-to the changing conditions of the underlying infrastructure.
-
-Resilient microservice VNFCs are highly observable, highly resilient and
-secure. VNF resiliency can typically be met through redundancy often
-supported by distributed systems architectures. This is another reason
-for favoring smaller VNFCs. By having more instances of smaller VNFCs it
-is possible to spread the instance out across servers, racks,
-datacenters, and geographic regions. This level of redundancy can
-mitigate most failure scenarios and has the potential to provide a
-service with even greater availability than the old model. Careful
-consideration of VNFC modularity also minimizes the impact of failures
-when an instance does fail.
-
-Security
-~~~~~~~~
-
-Security must be integral to the VNF through its design, development,
-instantiation, operation, and retirement phases. VNF architectures
-deliver new security capabilities that make it easier to maximize
-responsiveness during a cyber-attack and minimize service interruption
-to the customers. SDN enables the environment to expand and adapt for
-additional traffic and incorporation of security solutions. Further,
-additional requirements will exist to support new security capabilities
-as well as provide checks during the development and production stages
-to assure the expected advantages are present and compensating controls
-exist to mitigate new risks.
-
-New security requirements will evolve along with the new architecture.
-Initially, these requirements will fall into the following categories:
-
-- VNF General Security Requirements
-
-- VNF Identity and Access Management Requirements
-
-- VNF API Security Requirements
-
-- VNF Security Analytics Requirements
-
-- VNF Data Protection Requirements
-
-DevOps
-~~~~~~
-
-The ONAP software development and deployment methodology is evolving
-toward a DevOps model. VNF development and deployment should evolve in
-the same direction, enabling agile delivering of end-to-end services.
-Following these same principles better positions ONAP and VNF
-development to coevolve in the same direction.
-
-Testing
-^^^^^^^
-
-VNF packages should provide comprehensive automated regression,
-performance and reliability testing with VNFs based on open industry
-standard testing tools and methodologies. VNF packages should provide
-acceptance and diagnostic tests and in-service instrumentation to be
-used in production to validate VNF operation.
-
-Build and Deployment Processes
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-VNF packages should include continuous integration and continuous
-deployment (CI/CD) software artifacts that utilize automated open
-industry standard system and container build tools. The VNF package
-should include parameterized configuration variables to enable automated
-build customization. Don’t create unique (snowflake) VNFs requiring any
-manual work or human attention to deploy. Do create standardized (Lego™)
-VNFs that can be deployed in a fully automated way.
-
-ONAP will orchestrate updates and upgrades of VNFs. The target method
-for updates and upgrades is to onboard and validate the new version,
-then build a new instance with the new version of software, transfer
-traffic to that instance and kill the old instance. There should be no
-need for the VNF or its components to provide an update/upgrade
-mechanism.
-
-Automation
-^^^^^^^^^^
-
-Increased automation is enabled by VNFs and VNF design and composition.
-VNF and VNFCs should provide the following automation capabilities, as
-triggered or managed via ONAP:
-
-- Events and alarms
-
-- Lifecycle events
-
-- Zero-Touch rolling upgrades and downgrades
-
-- Configuration
-
-ONAP Ready
-----------
-
-ONAP is the “brain” providing the lifecycle management and control of
-software-centric network resources, infrastructure and services. ONAP is
-critical in achieving the objectives to increase the value of the
-Network Cloud to customers by rapidly on-boarding new services, enabling
-the creation of a new ecosystem of consumer and enterprise services,
-reducing capital and operational expenditures, and providing operations
-efficiencies. It delivers enhanced customer experience by allowing them
-in near real-time to reconfigure their network, services, and capacity.
-
-For more details, refer to the `*ECOMP Architecture White
-Paper* <http://att.com/ecomp>`__\ [14]_ which inspired the ONAP
-community effort.
-
-One of the main ONAP responsibilities is to rapidly onboard and enrich
-VNFs to be cataloged as resources to allow composition and deployment of
-services in a multi-vendor plug and play environment. It is also
-extremely important to be able to automatically manage the VNF run-time
-lifecycle to fully realize benefits of NFV. The VNF run-time lifecycle
-includes aspects such as instantiation, configuration, elastic scaling,
-automatic recovery from resource failures, and resource allocation. It
-is therefore imperative to provide VNFs that are equipped with
-well-defined capabilities that comply with ONAP standards to allow rapid
-onboarding and automatic lifecycle management of these resources when
-deploying services as depicted in **Figure 2**.
-
-|image1|
-
-**Figure 2. VNF Complete Lifecycle Stages**
-
-In order to realize these capabilities within the ONAP platform, it is
-important to adhere to a set of key principles (listed below) for VNFs
-to integrate into ONAP.
-
-Requirements for ONAP Ready can be found in the *VNF Management
-Requirements for ONAP* document.
-
-Design Definition
-~~~~~~~~~~~~~~~~~
-
-Onboarding automation will be facilitated by applying standards-based
-approaches to VNF packaging to describe the VNF’s infrastructure
-resource requirements, topology, licensing model, design constraints,
-and other dependencies to enable successful VNF deployment and
-management of VNF configuration and operational behavior.
-
-The current VNF Package Requirement is based on a subset of the
-Requirements contained in the ETSI Document: ETSI GS NFV-MAN 001 v1.1.1
-and GS NFV IFA011 V0.3.0 (2015-10) - Network Functions Virtualization
-(NFV), Management and Orchestration, VNF Packaging Specification.
-
-Configuration Management
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-ONAP must be able to orchestrate and manage the VNF configuration to
-provide fully automated environment for rapid service provisioning and
-modification. VNF configuration/reconfiguration must be allowed directly
-through standardized APIs without the need for an EMS.
-
-Monitoring and Management
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The end-to-end service reliability and availability in a virtualized
-environment will greatly depend on the ability to monitor and manage the
-behavior of Virtual Network Functions in real-time. ONAP platform must
-be able to monitor the health of the network and VNFs through collection
-of event and performance data directly from network resources utilizing
-standardized APIs without the need for an EMS. The VNF provider must
-provide visibility into VNF performance and fault at the VNFC level
-(VNFC is the smallest granularity of functionality in our architecture)
-to allow ONAP to proactively monitor, test, diagnose and trouble shoot
-the health and behavior of VNFs at their source.
-
-Virtualization Environment Ready
---------------------------------
-
-Every Network Cloud Service Provider will have a different set of
-resources and capabilities for their Network Cloud, but there are some
-common resources and capabilities that nearly every NCSP will offer.
-
-Network Cloud
-~~~~~~~~~~~~~
-
-VNFCs should be agnostic to the details of the Network Cloud (such as
-hardware, host OS, Hypervisor or container technology) and must run on
-the Network Cloud with acknowledgement to the paradigm that the Network
-Cloud will continue to rapidly evolve and the underlying components of
-the platform will change regularly. VNFs should be prepared to move
-VNFCs across VMs, hosts, locations or datacenters, or Network Clouds.
-
-Overlay Network
-~~~~~~~~~~~~~~~
-
-VNFs should be compliant with the Network Cloud network virtualization
-platform including the specific set of characteristics and features.
-
-The Network Cloud is expected to be tuned to support VNF performance
-requirements. Initially, specifics may differ per Network Cloud
-implementation and are expected to evolve over time, especially as the
-technology matures.
-
-Guest Operating Systems
-~~~~~~~~~~~~~~~~~~~~~~~
-
-VNFs should use the NCSP’s standard set of OS images to enable
-compliance with security, audit, regulatory and other needs.
-
-Compute Flavors
-~~~~~~~~~~~~~~~
-
-VNFs should take advantage of the standard Network Cloud capabilities in
-terms of VM characteristics (often referred to as VM Flavors), VM sizes
-and cloud acceleration capabilities aimed at VNFs such as Data Plane
-Development Kit (DPDK [15]_).
-
-Summary
-=======
-
-The intent of these guidelines and requirements is to provide long term
-vision as well as short term focus and clarity where no current open
-source implementation exists today. The goal is to accelerate the
-adoption of VNFs which will increase innovation, minimize customization
-to onboard VNFs, reduce implementation time and complexity as well as
-lower overall costs for all stakeholders. It is critical for the
-Industry to align on a set of standards and interfaces to quickly
-realize the benefits of NFV. AT&T is contributing these guidelines to
-the ONAP open source community as a step in moving toward standards.
-These guidelines are based on our experience with large scale deployment
-and operations of VNFs over the past several years.
-
-This VNF guidelines document provides a general overview and points to
-more detailed requirements documents. The subtending documents provide
-more detailed requirements and are listed in Appendix B - References.
-All documents are expected to evolve.
-
-Some of these VNF guidelines may be more broadly applicable in the
-industry, e.g., in other open source communities or standards bodies.
-The art of VNF architecture and development is expected to mature
-rapidly with practical deployment and operations experience from a
-broader ecosystem of types of VNFs and different VNF providers.
-Individual operators may also choose to provide their own extensions and
-enhancements to support their particular operational processes, but
-these guidelines are expected to remain broadly applicable across a
-number of service providers interested in acquiring VNFs.
-
-We invite feedback on these VNF Guidelines via
-`VNFGuidelines@list.att.com <mailto:VNFGuidelines@list.att.com?subject=VNF%20Guidelines%20and%20Requirements%20Feedback>`__.
-The ONAP Community has an active project, `VNF
-Requirements <https://wiki.onap.org/display/DW/VNF+Requirements+Project>`__, to
-deliver a unified set of VNF Guidelines and Requirements. Interested
-parties are encouraged to participate.

-+-------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
-| **Heat** | Heat is a service to orchestrate composite cloud applications using a declarative template format through an OpenStack-native REST API. |
-+===========================================+===========================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================+
-| **Network Clouds** | Network Clouds are built on a framework containing these essential elements: refactoring hardware elements into software functions running on commodity cloud computing infrastructure; aligning access, core, and edge networks with the traffic patterns created by IP based services; integrating the network and cloud technologies on a software platform that enables rapid, highly automated, deployment and management of services, and software defined control so that both infrastructure and functions can be optimized across change in service demand and infrastructure availability; and increasing competencies in software integration and a DevOps operations model. |

-| **Targeted Virtualization Environment** | Targeted Virtualization Environment is the execution environment for VNFs. While Network Clouds located in datacenters are a common execution environment, VNFs can and will be deployed in various locations (e.g., non-datacenter environments) and form factors (e.g., enterprise Customer Premise Equipment). Non-datacenter environments are expected to be available at more distributed network locations including central offices and at the edge of the NCSP’s infrastructure. |

-| **VM** | Virtual Machine (VM) is a virtualized computation environment that behaves very much like a physical computer/server. A VM has all its ingredients (processor, memory/storage, interfaces/ports) of a physical computer/server and is generated by a hypervisor, which partitions the underlying physical resources and allocates them to VMs. Virtual Machines are capable of hosting a virtual network function component (VNFC). |
-+-------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
-| **VNF** | Virtual Network Function (VNF) is the software implementation of a function that can be deployed on a Network Cloud. It includes network functions that provide transport and forwarding. It also includes other functions when used to support network services, such as network-supporting web servers and database. |

-Appendix C - Comparison between VNF Guidelines and ETSI GS NFV-SWA 001
-======================================================================
-
-The VNF guidelines presented in this document (VNF Guidelines) overlap
-with the ETSI GS NFV-SWA 001 (Network Functions Virtualization (NFV);
-Virtual Network Function Architecture) document. For convenience, we
-will just refer to this document as SWA 001.
-
-The SWA 001 document is a survey of the landscape for architecting a
-VNF. It includes many different options for building a VNF that take
-advantage of the ETSI MANO architecture.
-
-The Network Cloud and ONAP have similarities to ETSI’s MANO, but also
-have differences described in earlier sections. The result is
-differences in the VNF requirements. Since these VNF Guidelines are for
-a specific implementation of an architecture they are narrower in scope
-than what is specified in the SWA 001 document.
-
-The VNF Guidelines primarily overlaps the SWA 001 in Sections 4 and 5.
-The other sections of the SWA 001 document lie outside the scope of the
-VNF Guidelines.
-
-This appendix will describe the differences between these two documents
-indexed on the SWA 001 sections
-
-Section 4 Overview of VNF in the NFV Architecture
--------------------------------------------------
-
-This section provides an overview of the ETSI NFVI architecture and how
-it interfaces with the VNF architecture. Because of the differences
-between infrastructure architectures there will naturally be some
-differences in how it interfaces with the VNF.
-
-A high level view of the differences in architecture can be found in the
-main body of this document and a more detailed analysis can be found in
-the *ECOMP Architecture White Paper*\ [16]_.
-
-Section 4.3 Interfaces
-~~~~~~~~~~~~~~~~~~~~~~
-
-Since ONAP provides the VNFM and EMS functionality for all VNFs the
-SWA-3 and SWA-4 interfaces are ONAP interfaces. All ONAP interfaces are
-described in this package of documents.
-
-Section 5 VNF Design Patterns and Properties
---------------------------------------------
-
-This section of the SWA 001 document gives a broad view of all the
-possible design patterns of VNFs. The VNF Guidelines do not generally
-differ from this section. The VNF Guidelines address a more specific
-scope than what is allowed in the SWA 001 document.
-
-Section 5.1 VNF Design Patterns
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The following are differences between the VNF Guidelines and SWA-001:
-
-- 5.1.2 - The Network Cloud does not recognize the distinction between
- “parallelizable” and “non-parallelizable” VNFCs, where parallelizable
- means that there can be multiple instances of the VNFC. In the VNF
- Guidelines, all VNFCs should support multiple instances and therefore
- be parallelizable.
-
-- 5.1.3 - The VNF Guidelines encourages the use of stateless VNFCs.
- However, where state is needed it should be kept external to the VNFC
- to enable easier failover
-
-- 5.1.5 - The VNF Guidelines only accepts horizontal scaling (scale
- out/in) by VNFC. Vertical scaling (scale up/down) is not supported by
- ONAP.
-
-- 5.1.5 - Since ONAP provides all EMS and VNFM functionality On-Demand
- scaling is accomplished through ONAP and not directly by the VNF
-
-Section 5.2 VNF Update and Upgrade
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-- 5.2.2 - ONAP will orchestrate updates and upgrades. The preferred
- method for updates and upgrades is to build a new instance with the
- new version of software, transfer traffic to that instance and kill
- the old instance
-
-Section 5.3 VNF Properties
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The following are differences between the VNF Guidelines and SWA-001:
-
-- 5.3.1 - In a Network Cloud all VNFs must be only “COTS-Ready”. The
- VNF Guidelines does not support “Partly COTS-READY” or “Hardware
- Dependent”.
-
-- 5.3.2 – The only virtualization environment currently supported by
- ONAP is “Virtual Machines”. The VNF Guidelines state that all VNFs
- should be hypervisor agnostic. Other virtualized environment options
- such as containers are not currently supported. However, container
- technology is targeted to be supported in the future.
-
-- 5.3.3 - All VNFs must scale horizontally (scale out/in) within the
- Network Cloud. Vertical (scale up/down) is not supported.
-
-- 5.3.5 - The VNF Guidelines state that ONAP will provide full policy
- management for all VNFs. The VNF will not provide its own policy
- management for provisioning and management.
-
-- 5.3.7 - The VNF Guidelines recognizes both stateless and stateful
- VNFCs but it encourages the minimization of stateful VNFCs.
-
-- 5.3.11 - The VNF Guidelines only allows for ONAP management of the
- VNF. It does not allow a proprietary management interface for use
- with a 3rd party EMS
-
-Section 5.4 Attributes describing VNF Requirements
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Attributes described in the VNF Guidelines and reference documents
-include those attributes defined in this section of the SWA 001 document
-but also include additional attributes.

-
-The ONAP platform is the part of the larger Network Function
-Virtualization/Software Defined Network (NFV/SDN) ecosystem that is
-responsible for the efficient control, operation and management of
-Virtual Network Function (VNF) capabilities and functions. It specifies
-standardized abstractions and interfaces that enable efficient
-interoperation of the NVF/SDN ecosystem components. It enables
-product/service independent capabilities for design, creation and
-runtime lifecycle management (includes all aspects of installation,
-change management, assurance, and retirement) of resources in NFV/SDN
-environment (see `ECOMP white paper <http://att.com/ecomp>`__\ [1]_).
-These capabilities are provided using two major architectural
-frameworks: (1) a Design Time Framework to design, define and program
-the platform (uniform onboarding), and (2) a Runtime Execution Framework
-to execute the logic programmed in the design environment (uniform
-delivery and runtime lifecycle management). The platform delivers an
-integrated information model based on the VNF package to express the
-characteristics and behavior of these resources in the Design Time
-Framework. The information model is utilized by Runtime Execution
-Framework to manage the runtime lifecycle of the VNFs. The management
-processes are orchestrated across various modules of ONAP to
-instantiate, configure, scale, monitor, and reconfigure the VNFs using a
-set of standard APIs provided by the VNF developers.
-
-Design Definition
-=================
-
-The ONAP Design Time Framework provides the ability to design NFV
-resources including VNFs, Services, and products. The vendor must
-provide VNF packages that include a rich set of recipes, management and
-functional interfaces, policies, configuration parameters, and
-infrastructure requirements that can be utilized by the ONAP Design
-module to onboard and catalog these resources. Initially this
-information may be provided in documents, but in the near future a
-method will be developed to automate as much of the transfer of data as
-possible to satisfy its long term requirements.
-
-The current VNF Package Requirement is based on a subset of the
-Requirements contained in the ETSI Document: ETSI GS NFV-MAN 001 v1.1.1
-and GS NFV IFA011 V0.3.0 (2015-10) - Network Functions Virtualization
-(NFV), Management and Orchestration, VNF Packaging Specification.

-Configuration Management
-========================
-
-ONAP interacts directly with VNFs through its Network and Application
-Adapters to perform configuration activities within NFV environment.
-These activities include service and resource
-configuration/reconfiguration, automated scaling of resources, service
-and resource removal to support runtime lifecycle management of VNFs and
-services. The Adapters employ a model driven approach along with
-standardized APIs provided by the VNF developers to configure resources
-and manage their runtime lifecycle.
-
-NETCONF Standards and Capabilities
-----------------------------------
-
-ONAP Controllers and their Adapters utilize device YANG model and
-NETCONF APIs to make the required changes in the VNF state and
-configuration. The VNF providers must provide the Device YANG model and
-NETCONF server supporting NETCONF APIs to comply with target ONAP and
-industry standards.
-

-| REST APIs | The HealthCheck RPC, executes a vendor-defined VNF Healthcheck over the scope of the entire VNF (e.g., if there are multiple VNFCs, then run a health check, as appropriate, for all VNFCs). It returns a 200 OK if the test completes. A JSON object is returned indicating state (healthy, unhealthy), scope identifier, time-stamp and one or more blocks containing info and fault information. | Must | 12190 |

-Chef Standards and Capabilities
--------------------------------
-
-ONAP will support configuration of VNFs via Chef subject to the
-requirements and guidelines defined in this section.
-
-The Chef configuration management mechanism follows a client-server
-model. It requires the presence of a Chef-Client on the VNF that will be
-directly managed by a Chef Server. The Chef-client will register with
-the appropriate Chef Server and are managed via ‘cookbooks’ and
-configuration attributes loaded on the Chef Server which contain all
-necessary information to execute the appropriate actions on the VNF via
-the Chef-client.
-
-ONAP will utilize the open source Chef Server, invoke the documented
-Chef REST APIs to manage the VNF and requires the use of open source
-Chef-Client and Push Jobs Client on the VNF
-(https://downloads.chef.io/).
-

-| **Principle** | **Description** | **Type** | **ID #** |
-+============================+===============================================================================================================================================================================================================================================================================================================+============+============+
-| Chef Server Requirements | ONAP will interact with the Chef Server designated to manage a target VNF. ONAP design allows for the VNF to register with the following types of Chef Server [3]_: | Must | 12310 |
-| | | | |
-| | - **Chef Server hosted by ONAP**: ONAP will provide a Chef Server to manage a VNF. If this choice is used then it is required that the VNF Vendor provide all relevant cookbooks to ONAP to be loaded on the Chef Server. | | |
-| | | | |
-| | - **Chef Server hosted in Tenant Space**: The Chef Server may also be hosted external to ONAP in tenant space. Same guidelines as ONAP Chef Server apply. In addition, the owner is required to provide appropriate credentials to ONAP in order to interact with the Chef Server. | | |
-+----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| Chef Client | It is required that as part of the installation process, the chef-client on the VNF be preloaded with validator keys and configuration to register with the designated Chef Server. | Must | 12320 |
-| | | | |
-| Requirements | | | |
-+----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | All the endpoints (VMs) of a VNF that contain chef-clients are required to have routable FQDNs which are used to register with the Chef Server. As part of invoking VNF actions, ONAP will trigger push jobs against FQDNs of endpoints for a VNF, if required. | Must | 12330 |
-+----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | It is recommended that each VNF expose a single endpoint that is responsible for all functionality. | May | 12331 |
-+----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | It is required that the VNF be installed with | Must | 12340 |
-| | | | |
-| | - Chef-Client >= 12.0 | | |
-| | | | |
-| | - Chef push jobs client >= 2.0 | | |
-+----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| Chef Roles/ | Each VNF Vendor is required to make available for loading on appropriate Chef Server, all relevant Chef artifacts (roles/cookbooks/recipes) required to execute VNF actions requested by ONAP. | Must | 12350 |
-| | | | |
-| Requirements | | | |
-+----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | For each supported VNF action, the VNF Vendor is required to provide a run list of roles/cookbooks/recipes that will perform the desired VNF action in its entirety as specified by ONAP (see Section 3.5 for list of VNF actions and requirements), when triggered by a chef-client run list in JSON file. | Must | 12360 |
-+----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | Roles/cookbooks/recipes invoked for a VNF action must not contain any instance specific parameters for the VNF. Instead they must accept all necessary instance specific data from the environment or node object attributes. | Must | 12370 |
-+----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | It is required that all configurable parameters in the roles, cookbooks and recipes that can be set by ONAP, over-ride any default values. | Must | 12380 |
-+----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | It is required that when executing a VNF action, if the chef-client run encounters any critical errors/failures, it update status on the Chef Server appropriately (e.g., via a fail or raise an exception). | Must | 12390 |
-+----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | If the VNF action requires the output of a chef-client run be made available (e.g., get running configuration), an attribute, defined as node[‘PushJobOutput’] must be populated with the desired output on all nodes in the push job that execute chef-client run. | Must | 12400 |
-+----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | It is recommended that, for actions that change state of the VNF (e.g., configure), the Vendor design appropriate cookbooks that can automatically ‘rollback’ to the original state in case of any errors. | Must | 12410 |
-+----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | It is recommended that any chef-client run associated with a VNF action support callback URLs to return information to ONAP upon completion of the chef-client run. | Should | 12420 |
-| | | | |
-| | - As part of the push job, ONAP will provide two parameters in the environment of the push job JSON object: | | |
-| | | | |
-| | - ‘RequestId’ a unique Id to be used to identify the request, | | |
-| | | | |
-| | - ‘CallbackUrl’, the URL to post response back. | | |
-| | | | |
-| | - If the CallbackUrl field is empty or missing in the push job, then the chef-client run need not post the results back via callback. | | |
-| | | | |
-| | - If the chef-client run list includes a cookbook/recipe that is callback capable, it is required to, upon completion of the chef-client run, POST back on the callback URL, a JSON object as described in Table A2. | | |
-| | | | |
-| | - Failure to POST on the Callback Url should not be considered a critical error. That is, if the chef-client successfully completes the VNF action, it should reflect this status on the Chef Server regardless of whether the Callback succeeded or not. | | |

-
-ONAP Chef API Usage
-~~~~~~~~~~~~~~~~~~~
-
-This section outlines the workflow that ONAP invokes when it receives an
-action request against a Chef managed VNF.
-
-1. When ONAP receives a request for an action for a Chef Managed VNF, it
- retrieves the corresponding template (based on **action** and
- **VNF)** from its database and sets necessary values in the
- “Environment”, “Node” and “NodeList” keys (if present) from either
- the payload of the received action or internal data.
-
-2. If “Environment” key is present in the updated template, it posts the
- corresponding JSON dictionary to the appropriate Environment object
- REST endpoint on the Chef Server thus updating the Environment
- attributes on the Chef Server.
-
-3. Next, it creates a Node Object from the “Node” JSON dictionary for
- all elements listed in the NodeList (using the FQDN to construct the
- endpoint) by replicating it [4]_. As part of this process, it will
- set the name field in each Node Object to the corresponding FQDN.
- These node objects are then posted on the Chef Server to
- corresponding Node Object REST endpoints to update the corresponding
- node attributes.
-
-4. If PushJobFlag is set to “True” in the template, ONAP requests a push
- job against all the nodes in the NodeList to trigger
- chef-client\ **.** It will not invoke any other command via the push
- job. ONAP will include a callback URL in the push job request and a
- unique Request Id. An example push job posted by ONAP is listed
- below:
-
- {
-
- "command": "chef-client",
-
- "run\_timeout": 300,
-
- "nodes”: [“node1.vnf\_a.onap.com”, “node2.vnf\_a.onap.com”],
-
- "env": {
-
- “RequestId”:”8279-abcd-aksdj-19231”,
-
- “CallbackUrl”:”<callback url>”
-
- },
-
- }
-
-5. If CallbackCapable field in the template is not present or set to
- “False” ONAP will poll the Chef Server to check completion status of
- the push job.
-
-6. If “GetOutputFlag” is set to “True” in the template and
- CallbackCapable is not set to “True”, ONAP will retrieve any output
- from each node where the push job has finished by accessing the Node
- Object attribute node[‘PushJobOutput’].
-
-Ansible Standards and Capabilities
-----------------------------------
-
-ONAP will support configuration of VNFs via Ansible subject to the
-requirements and guidelines defined in this section.
-
-Ansible allows agentless management of VMs via execution of ‘playbooks’
-over ssh. The ‘playbooks’ are a structured set of tasks which contain
-all the necessary data and execution capabilities to take the necessary
-action on one or more target VMs of the VNF. ONAP will utilize the
-framework of an Ansible Server that will host and invoke playbooks to
-manage VNFs that support Ansible.
-
-**Table 7. VNF Configuration via Ansible**

-+===============================+========================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================+============+============+
-| Ansible Server Requirements | ONAP will utilize an Ansible server in order to manage VNFs that support Ansible playbooks. We note that Ansible in general does not require the use of a server. However, this framework has been adopted to align with ONAP architecture, ease of management and scalability. | Must | 12510 |
-| | | | |
-| | All playbooks for the VNF will be hosted on a designated Ansible Server that meets ONAP Ansible API requirements. ONAP design allows for VNFs to be managed by an Ansible Server in any of the two following forms [5]_: | | |
-| | | | |
-| | - **Ansible Server hosted by ONAP**: ONAP will provide an Ansible Server to manage a VNF. If this choice is used then it is required that the VNF Vendor provide all relevant playbooks to ONAP to be loaded on the Ansible Server. | | |
-| | | | |
-| | - **Ansible Server hosted in Tenant Space**: Same guidelines as the ONAP Ansible Server. The Ansible Server must meet the ONAP Ansible Server API Interface requirements. | | |
-+-------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| Ansible Client | The endpoints (VMs) of a VNF on which playbooks will be executed must have routable FQDNs that are reachable via the Ansible Server. ONAP will initiate requests to the Ansible Server for invocation of playbooks against these end points [6]_. | Must | 12520 |
-| | | | |
-| Requirements | | | |
-+-------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | It is recommended that a VNF typically have a single endpoint. | May | 12521 |
-+-------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | The endpoint VM(s) of a VNF on which an Ansible playbook will be executed is required to have Python >= 2.7. | Must | 12530 |
-+-------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | The endpoint VM(s) must support SSH and allow SSH access to the Ansible server in line with Network Cloud Service Provider guidelines for authentication and access. | Must | 12540 |
-+-------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| Ansible Playbook | An Ansible playbook is a collection of tasks that is executed on the Ansible server (local host) and/or the target VM (s) in order to complete the desired action. Each VNF Vendor is required to make available (or load on VNF Ansible Server) playbooks that conform to the ONAP requirements. | Must | 12550 |
-| | | | |
-| Requirements | | | |
-+-------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | It is required that each VNF action be supported by invocation of **one** playbook [7]_. The playbook will be responsible for executing all necessary tasks (as well as calling other playbooks) to complete the request. | Must | 12560 |
-+-------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | A playbook must not contain any instance specific parameters. It must utilize information from key value pairs that will be provided by the Ansible Server as extra-vars during invocation to execute the desired VNF action. If the playbook requires files, they must also be supplied using the methodology detailed in the Ansible Server API. | Must | 12570 |
-+-------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | The Ansible Server will determine if a playbook invoked to execute a VNF action finished successfully or not using the “PLAY\_RECAP” summary in Ansible log. The playbook will be considered to successfully finish only if the “PLAY RECAP” section at the end of playbook execution output has no unreachable hosts and no failed tasks. Otherwise, the playbook will be considered to have failed. | Must | 12580 |
-+-------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+

-ONAP Controller APIs and Behavior
----------------------------------
-
-ONAP Controllers support the following operations which act directly
-upon the VNF. Most of these utilize the NETCONF interface. There are
-additional commands in use but these either act internally on Controller
-itself or depend upon network cloud components for implementation. Those
-actions do not put any special requirement on the VNF provider.
-
-The following table summarizes how the VNF must act in response to
-commands from ONAP.
-
-Table 8. ONAP Controller APIs and NETCONF Commands
-
-+---------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
-| **Action** | **Description** | **NETCONF Commands** |
-+=====================+==================================================================================================================================================================================================================================================================================+===============================================================================================================================================================================================================================+
-| Action | Queries ONAP Controller for the current state of a previously submitted runtime LCM (Lifecycle Management) action. | There is currently no way to check the request status in NETCONF so action status is managed internally by the ONAP controller. |
-| | | |
-| Status | | |
-+---------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
-| Audit, Sync | Compare active (uploaded) configuration against the current configuration in the ONAP controller. Audit returns failure if different. Sync considers the active (uploaded) configuration as the current configuration. | The <get-config> operation is used to retrieve the running configuration from the VNF. |
-+---------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
-| Lock, | Returns true when the given VNF has been locked. | There is currently no way to query lock state in NETCONF so VNF locking and unlocking is managed internally by the ONAP controller. |
-| | | |
-| Unlock, | | |
-| | | |
-| CheckLock | | |
-+---------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
-| Configure, | Configure applies a post-instantiation configuration the target VNF or VNFC. ConfigModify updates only a subset of the total configuration parameters of a VNF. | The <edit-config> operation loads all or part of a specified configuration data set to the specified target database. If there is no <candidate/> database, then the target is the <running/> database. A <commit> follows. |
-| | | |
-| ConfigModify | | |
-+---------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
-| Health | Executes a VNF health check and returns the result. A health check is VNF-specific. | The ONAP health check interface is defined over REST and requires the target VNF to expose a standardized HTTP(S) interface for that purpose. See Section 3.2. |
-| | | |
-| Check | | |
-+---------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
-| StartApplication, | ONAP requests application to be started or stopped on the VNF or VNFC. These actions do not need to be supported if (1) the application starts automatically after Configure or if the VM’s are started and (2) the application gracefully shuts down if the VM’s are stopped. | These commands have no specific NETCONF RPC action. |
-| | | |
-| StopApplication | | They can be supported using Ansible or Chef (see Table 9 below). |
-+---------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
-| SoftwareUpload, | Upgrades the target VNF to a new version without interrupting VNF operation. | These commands have no specific NETCONF RPC action. |
-| | | |
-| LiveUpgrade | | They can be supported using Ansible or Chef (see Table 9 below). |

-+------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
-| ConfigRecovery | ConfigRecovery is used to replace the running configuration with a recovery configuration. This recovery configuration is stored in the ONAP Controller and is the configuration uploaded after instantiation.

-Monitoring & Management
-=======================
-
-This section addresses data collection and event processing
-functionality that is directly dependent on the interfaces provided by
-the VNFs’ APIs. These can be in the form of asynchronous interfaces for
-event, fault notifications, and autonomous data streams. They can also
-be synchronous interfaces for on-demand requests to retrieve various
-performance, usage, and other event information.
-
-The target direction for VNF interfaces is to employ APIs that are
-implemented utilizing standardized messaging and modeling protocols over
-standardized transports. Migrating to a virtualized environment presents
-a tremendous opportunity to eliminate the need for proprietary
-interfaces for vendor equipment while removing the traditional
-boundaries between Network Management Systems and Element Management
-Systems. Additionally, VNFs provide the ability to instrument the
-networking applications by creating event records to test and monitor
-end-to-end data flow through the network, similar to what physical or
-virtual probes provide without the need to insert probes at various
-points in the network. The VNF vendors must be able to provide the
-aforementioned set of required data directly to the ONAP collection
-layer using standardized interfaces.
-
-Transports and Protocols Supporting Resource Interfaces
--------------------------------------------------------
-
-Delivery of data from VNFs to ONAP must use the same common transport
-mechanisms and protocols for all VNFs. Transport mechanisms and
-protocols have been selected to enable both high volume and moderate
-volume datasets, as well as asynchronous and synchronous communications
-over secure connections. The specified encoding provides
-self-documenting content, so data fields can be changed as needs evolve,
-while minimizing changes to data delivery.
-
-The term ‘Event Record’ is used throughout this document to represent
-various forms instrumentation/telemetry made available by the VNF
-including, faults, status events and various other types of VNF
-measurements and logs. Headers received by themselves must be used as
-heartbeat indicators. The common structure and delivery protocols for
-other types of data will be given in future versions of this document as
-we get more insight into data volumes and required processing.
-
-In the following guidelines, we provide options for encoding,
-serialization and data delivery. Agreements between Service Providers
-and VNF vendors shall determine which encoding, serialization and
-delivery method to use for particular data sets. The selected methods
-must be agreed to prior to the on-boarding of the VNF into ONAP design
-studio.
-

-| **Principle** | **Description** | **Type** | **ID #** |
-+==============================================+=====================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================================+============+============+
-| VNF telemetry via standardized interface | VNFs must provide all telemetry (e.g., fault event records, syslog records, performance records etc.) to ONAP using the model, format and mechanisms described in this section. | Must | 13005 |
-+----------------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| Encoding and Serialization | Content delivered from VNFs to ONAP is to be encoded and serialized using JSON (option 1). High-volume data is to be encoded and serialized using Avro, where Avro data format are described using JSON (option 2) [8]_. | Must | 13010 |
-| | | | |
-| | - JSON plain text format is preferred for moderate volume data sets (option 1), as JSON has the advantage of having well-understood simple processing and being human-readable without additional decoding. Examples of moderate volume data sets include the fault alarms and performance alerts, heartbeat messages, measurements used for VNF scaling and syslogs. | | |
-| | | | |
-| | - Binary format using Avro is preferred for high volume data sets (option 2) such as mobility flow measurements and other high-volume streaming events (such as mobility signaling events or SIP signaling) or bulk data, as this will significantly reduce the volume of data to be transmitted. As of the date of this document, all events are reported using plain text JSON and REST. | | |
-| | | | |
-| | - Avro content is self-documented, using a JSON schema. The JSON schema is delivered along with the data content (http://avro.apache.org/docs/current/ ). This means the presence and position of data fields can be recognized automatically, as well as the data format, definition and other attributes. Avro content can be serialized as JSON tagged text or as binary. In binary format, the JSON schema is included as a separate data block, so the content is not tagged, further compressing the volume. For streaming data, Avro will read the schema when the stream is established and apply the schema to the received content. | | |
-| | | | |
-| | - In the future, we may consider support for other types of encoding & serialization (e.g., gRPC) based on industry demand. | | |
-+----------------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| Reporting Frequency | The frequency that asynchronous data is delivered will vary based on the content and how data may be aggregated or grouped together. For example, alarms and alerts are expected to be delivered as soon as they appear. In contrast, other content, such as performance measurements, KPIs or reported network signaling may have various ways of packaging and delivering content. Some content should be streamed immediately; or content may be monitored over a time interval, then packaged as collection of records and delivered as block; or data may be collected until a package of a certain size has been collected; or content may be summarized statistically over a time interval, or computed as a KPI, with the summary or KPI being delivered. | Must | 13020 |
-| | | | |
-| | - We expect the reporting frequency to be configurable depending on the virtual network function’s needs for management. For example, Service Provider may choose to vary the frequency of collection between normal and trouble-shooting scenarios. | | |
-| | | | |
-| | - Decisions about the frequency of data reporting will affect the size of delivered data sets, recommended delivery method, and how the data will be interpreted by ONAP. However, this should not affect deserialization and decoding of the data, which will be guided by the accompanying JSON schema. | | |
-+----------------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| Addressing and Delivery Protocol | ONAP destinations can be addressed by URLs for RESTful data PUT. Future data sets may also be addressed by host name and port number for TCP streaming, or by host name and landing zone directory for SFTP transfer of bulk files. | Must | 13030 |
-| | | | |
-| | - REST using HTTPS delivery of plain text JSON is preferred for moderate sized asynchronous data sets, and for high volume data sets when feasible.  | | |
-| | | | |
-| | - VNFs must have the capability of maintaining a primary and backup DNS name (URL) for connecting to ONAP collectors, with the ability to switch between addresses based on conditions defined by policy such as time-outs, and buffering to store messages until they can be delivered. At its discretion, the service provider may choose to populate only one collector address for a VNF. In this case, the network will promptly resolve connectivity problems caused by a collector or network failure transparently to the VNF. | | |
-| | | | |
-| | - VNFs will be configured with initial address(es) to use at deployment time. After that the address(es) may be changed through ONAP-defined policies delivered from ONAP to the VNF using PUTs to a RESTful API, in the same way that other controls over data reporting will be controlled by policy. | | |
-| | | | |
-| | - Other options are expected to include: | | |
-| | | | |
-| | - REST delivery of binary encoded data sets. | | |
-| | | | |
-| | - TCP for high volume streaming asynchronous data sets and for other high volume data sets. TCP delivery can be used for either JSON or binary encoded data sets. | | |
-| | | | |
-| | - SFTP for asynchronous bulk files, such as bulk files that contain large volumes of data collected over a long time interval or data collected across many VNFs. This is not preferred. Preferred is to reorganize the data into more frequent or more focused data sets, and deliver these by REST or TCP as appropriate. | | |
-| | | | |
-| | - REST for synchronous data, using RESTCONF (e.g., for VNF state polling). | | |
-| | | | |
-| | - The ONAP addresses as data destinations for each VNF must be provided by ONAP Policy, and may be changed by Policy while the VNF is in operation. We expect the VNF to be capable of redirecting traffic to changed destinations with no loss of data, for example from one REST URL to another, or from one TCP host and port to another. | | |
-+----------------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| Asynchronous and Synchronous Data Delivery | VNFs are to deliver asynchronous data as data becomes available, or according to the configured frequency. The delivered data must be encoded using JSON or Avro, addressed and delivered as described in the previous paragraphs. | Must | 13040 |

-+----------------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | ONAP may request the VNF to deliver the current data for any of the record types defined in Section 4.2 below. The VNF must respond by returning the requested record, populated with the current field values. (Currently the defined record types include the common header record, technology independent records such as Fault, Heartbeat, State Change, Syslog, and technology specific records such as Mobile Flow, Signaling and Voice Quality records.  Additional record types will be added in the future as they are standardized and become available.) | Must | 13080 |

-| | If YANG models need to be translated to and from JSON, (https://trac.tools.ietf.org/id/draft-lhotka-netmod-yang-json-00.html) should be utilized for translation, meaning YANG configuration and content can be represented via JSON, consistent with Avro, as described in “Encoding and Serialization” section. | Should | 13100 |

-Data Model for Event Records
------------------------------
-
-This section describes the data model for the collection of telemetry
-data from VNFs by Service Providers (SPs) to manage VNF health and
-runtime lifecycle. This data model is referred to as the VNF Event
-Streaming (VES) specifications. While this document is focused on
-specifying some of the records from the ONAP perspective, there may be
-other external bodies using the same framework to specify additional
-records. For example, OPNFV has a VES project [9]_ that is looking to
-specify records for OpenStack’s internal telemetry to manage Application
-(VNFs), physical and virtual infrastructure (compute, storage, network
-devices), and virtual infrastructure managers (cloud controllers, SDN
-controllers). Note that any configurable parameters for these data
-records (e.g., frequency, granularity, policy-based configuration) will
-be managed using the “Configuration” framework described in the prior
-sections of this document.
-
-The Data Model consists of:
-
-- Common Header Record: This data structure precedes each of the
- Technology Independent and Technology Specific records sections of
- the data model.
-
-- Technology Independent Records: This version of the document
- specifies the model for Fault, Heartbeat, State Change, Syslog,
- Threshold Crossing Alerts, and VF Scaling\* (short for
- measurementForVfScalingFields) records. In the future, these may be
- extended to support other types of technology independent records.
- Each of these records allows additional fields (name/ value pairs)
- for extensibility. The vendors can use these vendor-specific
- additional fields to provide additional information that may be
- relevant to the managing systems.
-
-- Technology Specific Records: This version of the document specifies
- the model for Mobile Flow records, Signaling and Voice Quality
- records. In the future, these may be extended to support other types
- of records (e.g., Network Fabric, Security records, etc.). Each of
- these records allows additional fields (name/value pairs) for
- extensibility. The VNF vendors can use these VNF-specific additional
- fields to provide additional information that may be relevant to the
- managing systems. A placeholder for additional technology specific
- areas of interest to be defined in the future documents has been
- depicted.

-Event Records - Data Structure Description
-------------------------------------------
-
-The data structure for event records consists of:
-
-- a Common Event Header block;
-
-- zero or more technology independent domain blocks; and
-
- - e.g., Fault domain, State Change domain, Syslog domain, etc.
-
-- zero or more technology specific domain blocks.
-
- - e.g., Mobile Flow domain, Signaling domain, Voice Quality domain,
- etc.
-
-Note: Heartbeat records would only have the Common Event Header block.
-An optional heartbeat domain is available if required by the heartbeat
-implementation.
-
-Common Event Header
-~~~~~~~~~~~~~~~~~~~~~
-
-The common header that precedes any of the domain-specific records
-contains information identifying the type of record to follow,
-information about the sender and other identifying characteristics
-related to timestamp, sequence number, etc.
-
-Technology Independent Records – Fault Fields
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The Fault Record, describing a condition in the Fault domain, contains
-information about the fault such as the entity under fault, the
-severity, resulting status, etc.
-
-Technology Independent Records – Heartbeat Fields
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The Heartbeat Record provides an optional structure for communicating

-The example JSON file provided by the vendor for each VNF action will be
-turned into a template by ONAP, that can be updated with instance
-specific values at run-time.
-
-Some points worth noting regarding the JSON fields:
-
-a. The JSON file must be created for each action for each VNF.
-
-b. If a VNF action involves multiple endpoints (VMs) of a VNF, ONAP will
- replicate the “Node” JSON dictionary in the template and post it to
- each FQDN (i.e., endpoint) in the NodeList after setting the “name”
- field in the Node object to be the respective FQDN [10]_. Hence, it
- is required that all end points (VMs) of a VNF involved in a VNF
- action support the same set of Node Object attributes.
-

-
-In the above example, the Ansible Server will:
-
-a. Process the “FileParameters” dictionary and generate a file named
- ‘config.txt’ with contents set to the value of the ‘config.txt’ key.
-
-b. Execute the playbook named ‘Ansible\_configure.yml’ on nodes with
- FQDNs test1.vnf\_b.onap.com and test2.vnf\_b.onap.com respectively
- while providing the following key value pairs to the playbook:
- Retry=3, Wait=5, ConfigFile=config.txt
-
-c. If execution time of the playbook exceeds 60 secs (across all hosts),
- it will be terminated.

-1. Entitlement and License Key Limits
-
-Limitations on the use of software entitlements and license keys may be
-based on factors such as: features enabled in the product, the allowed
-capacity of the product, number of installations, etc... The limits may
-generally be categorized as:
-
-- where (location)
-
-- when (time)
-
-- how (usages)
-
-- who/what (entity)
-
-- amount (how much)
-
-Multiple limits may be applicable for an entitlement or license key.
-Each limit may further be described by limit behavior, duration,
-quantification, aggregation, aggregation interval, start date, end date,
-and threshold.
-
-When the limit is associated with a quantity, the quantity is relative
-to an instance of the entitlement or license key. For example:
-
-- Each entitlement grants the right to 50 concurrent users. If 10
- entitlements are purchased, the total number of concurrent users
- permitted would be 500. In this example, the limit category is
- **amount**, the limit type is **users**, and the limit
- **quantification** is **50.**
-
- Each license key may be installed on 3 devices. If 5 license keys are
- acquired, the total number of devices allowed would be 15. In this
- example, the limit category is **usages**, the limit type is
- **device**, and the limit **quantification** is **3.**

-
-These limits describe terms relative to utilization of the functions of
-the software (for example, number of named users permitted, throughput,
-or capacity). Limits of this type may also be relative to utilization of
-other resources (for example, a limit for firewall software is not based

-**Appendix D – Ansible Server Specification**
-
-This section outlines the specifications for an ONAP compliant Ansible
-Server that can optionally be provided by the VNF Vendor. The Ansible
-Server will be used as a repository to store Ansible playbooks as well
-as an execution engine which upon a REST API request, will execute
-Ansible playbook against VNFs.
-
-Table D1. Ansible Server Requirements
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| **Principle** | **Description** | **Type** | **ID #** |
-+==============================================+==============================================================================================================================================================================================================================================================================================================================================================================+============+============+
-| Ansible Server Scope | The Ansible Server is required to support storage and execution of playbooks that are in yaml format or a collection of playbooks compressed and uploaded in tar-ball format. | Must | D1000 |
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | The Ansible Server must accept requests for execution of playbooks via a REST interface. The scope of each request will involve exactly one action and will request execution of one playbook. | Must | D1010 |
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | The playbook executed by the Ansible Server will be responsible for execution of the entire action against the VNF (e.g., calling other playbooks, running tasks on multiple VMs in the VNF) and return back the status of the action as well as any necessary output in its entirety after the action is finished. | Must | D1020 |
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | The Ansible Server must support simultaneous execution of multiple playbooks against different VNFs in parallel (i.e., process multiple requests). | Must | D1030 |
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | The Ansible Server will be loaded with all necessary credentials to invoke playbooks against target VNF(s). | Must | D1040 |
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| Ansible Server/ONAP Interface | Load Playbook\ **:** The Ansible Server must expose an authenticated interface to allow loading all necessary playbooks for a target VNF. It should impose an identification mechanism that allows each playbook to be uniquely identified. | Must | D1050 |
-| | | | |
-| | - It is recommended that the load Playbook API be a REST API. | | |
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | Request API: The Ansible Server must expose a REST endpoint that accepts a POST message to request execution of the playbook. The POST request must be a JSON block as outlined in Table D2. | Must | D1060 |
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | When the Ansible server accepts an authenticated request to execute a playbook, it is required to send back an initial response indicating whether the request is accepted or rejected. The response must be a JSON Object with the key value pairs as described in Table D3. | Must | D1070 |
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | Result API: If the Ansible Server accepts a request to execute a playbook, it must make available status of the execution of the playbook at a Results REST endpoint indexed by the Id in the request in the form <url>?Id=<RequestId>&Type=GetResult where <url> is the URL used for submitting requests. | Must | D1080 |
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | When a GET is invoked against the Results REST endpoint, the Ansible Server must reply with an appropriate response: | Must | D1090 |
-| | | | |
-| | - If the Endpoint is invalid (no request, or request expired), reply with a standard HTTP 404 error. | | |
-| | | | |
-| | - If the playbook execution is still ongoing, then the Ansible Server is required to block on the GET request till the execution finishes or terminates. | | |
-| | | | |
-| | - Upon completion of execution, the Ansible Server is required to respond to the GET request with the result of the playbook execution in the form of a JSON message as outlined in the Table D4. | | |
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| | The dictionary associated with the ‘Results’ key in the Result Response must be a key-value pair where each key corresponds to an entry in the NodeList and the value is a dictionary with the format as outlined in Table D5. | Must | D1100 |
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| Ansible Server Actions | The Ansible Server must take the following actions when triggered by a request to execute a playbook: | Must | D1110 |
-| | | | |
-| | - Determine if the request is valid, and if so, must send back an initial response message accepting the request. | | |
-| | | | |
-| | - If the request contains a “FileParameters” key that is not NULL, create all the necessary files. | | |
-| | | | |
-| | - Invoke the ansible playbook while providing it all appropriate parameters listed in EnvParameters and inventory information listed in NodeList. The playbook will be responsible for execution of all necessary steps required by the VNF action. | | |
-| | | | |
-| | - If the playbook finishes, use the PLAY\_RECAP functionality to determine whether playbook finished successfully on each endpoint identified in the NodeList. | | |
-| | | | |
-| | - If the playbook finishes, collect any output returned by the playbook. A playbook conforming to the ONAP vendor requirements document will write out any necessary output to a file named ‘<hostname>\_results.txt’ in the working directory, where ‘hostname’ is an element of the NodeList where the playbook is being executed. | | |
-| | | | |
-| | - If the playbook execution exceeds the Timeout value, the playbook execution process is terminated and ansible log that captures the last task executed is stored. | | |
-| | | | |
-| | - Make results available on the Results REST Endpoint as documented in Table D3. | | |
-| | | | |
-| | - If Callback url was provided in initial request, post the final response message on the Callback URL along with an additional key additional key “Id “: which corresponds to the request Id sent in the request. | | |
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| Ansible Server Result Storage Requirements | The Ansible Server must cache and provide results of an execution as well as retain logs for debugging purposes as outlined below: | Must | D1120 |
-| | | | |
-| | - The results from a playbook execution result must be retained by the Ansible Server and made available through the respective REST endpoint for a duration that is configurable. | | |
-| | | | |
-| | - Recommended duration is 2 x Timeout. | | |
-| | | | |
-| | - The log from a playbook must be stored by the Ansible Server, tagged with the Id along with all other parameters in the initial request in a format that allows for examination for debugging purposes. | | |
-| | | | |
-| | - The results from playbook execution and log files shall be removed after a configurable defined retention period for this type of file. | | |
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
-| Ansible Server Locking Mechanism | The Ansible Server shall lock VNF while running playbooks that require exclusive use of a VNF (Configure is an example) and not accept requests to run other playbooks or queue those requests until playbook that requires exclusivity completes | Must | D1130 |
-+----------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------+------------+
