TOSCA YAML ============= + +Introduction +------------- + +This reference document is the VNF TOSCA Template Requirements for +OpenO, which provides recommendations and standards for building VNF +TOSCA templates compatible with OpenO– initial implementations of +Network Cloud. It has the following features: + +1. VNF TOSCA template designer supports GUI and CLI. + +2. VNF TOSCA template is aligned to the newest TOSCA protocol, “Working + Draft 04-Revision 06”. + +3. VNF TOSCA template supports EPA features, such as NUMA, Hyper + Threading, SRIOV, etc. + +Intended Audience +----------------- + +This document is intended for persons developing VNF TOSCA templates +that will be orchestrated by OpenO. + +Scope +------ + +OpenO implementations of Network Cloud supports TOSCA Templates, also +referred to as TOSCA in this document. + +OpenO requires the TOSCA Templates to follow a specific format. This +document provides the mandatory, recommended, and optional requirements +associated with this format. + +Overview +--------- + +The document includes three charters to help the VNF vendors to use the +VNF model design tools and understand the VNF package structure and VNF +TOSCA templates. + +In the OPENO, VNF Package and VNFD template can be designed by manually +or via model designer tools. VNF model designer tools can provide the +GUI and CLI tools for the VNF vendor to develop the VNF Package and VNFD +template. + +The VNF package structure is align to the NFV TOSCA protocol, and +supports CSAR + +The VNFD and VNF package are all align to the NFV TOSCA protocol, which +supports multiple TOSCA template yaml files, and also supports +self-defined node or other extensions. + +NFV TOSCA Template +------------------ + +TOSCA templates supported by OPENO must follow the requirements +enumerated in this section. + +TOSCA Introduction +------------------ + +TOSCA defines a Meta model for defining IT services. This Meta model +defines both the structure of a service as well as how to manage it. A +Topology Template (also referred to as the topology model of a service) +defines the structure of a service. Plans define the process models that +are used to create and terminate a service as well as to manage a +service during its whole lifetime. + +A Topology Template consists of a set of Node Templates and Relationship +Templates that together define the topology model of a service as a (not +necessarily connected) directed graph. A node in this graph is +represented by a *Node Template*. A Node Template specifies the +occurrence of a Node Type as a component of a service. A *Node Type* +defines the properties of such a component (via *Node Type Properties*) +and the operations (via *Interfaces*) available to manipulate the +component. Node Types are defined separately for reuse purposes and a +Node Template references a Node Type and adds usage constraints, such as +how many times the component can occur. + +|image1| +Figure 1: Structural Elements of Service Template and their Relations + +TOSCA Modeling Principles & Data Model +-------------------------------------- + +This section describing TOSCA modeling principles and data model for +NFV, which shall be based on [TOSCA-1.0] and [TOSCA-Simple-Profile-YAML +V1.0], or new type based on ETSI NFV requirements, etc. + +VNF Descriptor Template +----------------------- + +The VNF Descriptor (VNFD) describes the topology of the VNF by means of +ETSI NFV IFA011 [IFA011] terms such as VDUs, Connection Points, Virtual +Links, External Connection Points, Scaling Aspects, Instantiation Levels +and Deployment Flavours. + +The VNFD (VNF Descriptor) is read by both the NFVO and the VNFM. It +represents the contract & interface of a VNF and ensures the +interoperability across the NFV functional blocks. + +The main parts of the VNFD are the following: + +- VNF topology: it is modeled in a cloud agnostic way using virtualized + containers and their connectivity. Virtual Deployment Units (VDU) + describe the capabilities of the virtualized containers, such as + virtual CPU, RAM, disks; their connectivity is modeled with VDU + Connection Point Descriptors (VduCpd), Virtual Link Descriptors (Vld) + and VNF External Connection Point Descriptors (VnfExternalCpd); + +- VNF deployment aspects: they are described in one or more deployment + flavours, including instantiation levels, supported LCM operations, + VNF LCM operation configuration parameters, placement constraints + (affinity / antiaffinity), minimum and maximum VDU instance numbers, + and scaling aspect for horizontal scaling. + +The following table defines the TOSCA Type “derived from” values that +SHALL be used when using the TOSCA Simple Profile for NFV version 1.0 +specification [TOSCA-Simple-Profile-NFV-v1.0] for NFV VNFD. + ++-----------------------------------------+---------------------------------------+-----------------------+ +| **ETSI NFV Element** | **TOSCA VNFD** | **Derived from** | +| | | | +| **[IFA011]** | **[TOSCA-Simple-Profile-NFV-v1.0]** | | ++=========================================+=======================================+=======================+ +| VNF | tosca.nodes.nfv.VNF | tosca.nodes.Root | ++-----------------------------------------+---------------------------------------+-----------------------+ +| VDU | tosca.nodes.nfv.VDU | tosca.nodes.Root | ++-----------------------------------------+---------------------------------------+-----------------------+ +| Cpd (Connection Point) | tosca.nodes.nfv.Cpd | tosca.nodes.Root | ++-----------------------------------------+---------------------------------------+-----------------------+ +| VduCpd (internal connection point) | tosca.nodes.nfv.VduCpd | tosca.nodes.nfv.Cpd | ++-----------------------------------------+---------------------------------------+-----------------------+ +| VnfVirtualLinkDesc (Virtual Link) | tosca.nodes.nfv.VnfVirtualLinkDesc | tosca.nodes.Root | ++-----------------------------------------+---------------------------------------+-----------------------+ +| VnfExtCpd (External Connection Point) | tosca.nodes.nfv.VnfExtCpd | tosca.nodes.Root | ++-----------------------------------------+---------------------------------------+-----------------------+ +| Virtual Storage | | | ++-----------------------------------------+---------------------------------------+-----------------------+ +| Virtual Compute | | | ++-----------------------------------------+---------------------------------------+-----------------------+ +| Software Image | | | ++-----------------------------------------+---------------------------------------+-----------------------+ +| Deployment Flavour | | | ++-----------------------------------------+---------------------------------------+-----------------------+ +| Scaling Aspect | | | ++-----------------------------------------+---------------------------------------+-----------------------+ +| Element Group | | | ++-----------------------------------------+---------------------------------------+-----------------------+ +| Instantiation Level | | | ++-----------------------------------------+---------------------------------------+-----------------------+ + ++--------------------------------------------------------------------+ +| +--------------------------------------------------------------+ | +| | tosca\_definitions\_version: tosca\_simple\_yaml\_1\_0 | | +| | | | +| | description: VNFD TOSCA file demo | | +| | | | +| | imports: | | +| | | | +| | - TOSCA\_definition\_nfv\_1\_0.yaml | | +| | | | +| | - TOSCA\_definition\_nfv\_ext\_1\_0.yaml | | +| | | | +| | | **node\_types: | | +| | tosca.nodes.nfv.VNF.vOpenNAT: | | +| | derived\_from:** tosca.nodes.nfv.VNF | | +| | | **requirements: | | +| | **- **sriov\_plane: | | +| | capability:** tosca.capabilities.nfv.VirtualLinkable | | +| | | **node:** tosca.nodes.nfv.VnfVirtualLinkDesc | | +| | | **relationship:** tosca.relationships.nfv.VirtualLinksTo | | +| +--------------------------------------------------------------+ | ++====================================================================+ ++--------------------------------------------------------------------+ + +EPA Requirements +---------------- + +1.
