+ONAP Management Requirements

+
+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 ). 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.
+
+Although the guidelines and requirements specified in this document
+were originally driven by the need to standardize and automate the
+management of the virtualized environments (with VNFs) operated by
+Service Providers, we believe that most of the requirements are equally
+applicable to the operation of the physical network functions (PNFs),
+those network functions provided by traditional physical network
+elements (e.g. whitebox switches) or customized peripherals (e.g. a
+video rendering engine for augmented reality). The primary area of
+difference will be in how the network function is orchestrated into
+place – VNFs can be much more dynamically created & placed by ONAP
+to support varying geographic, availability and scalability needs,
+whereas the PNFs have to be deployed a priori in specific locations
+based on planning and engineering – their availability and scalability
+will be determined by the capabilities offered by the PNFs.
+
+**PNF** is a vendor-provided Network Function(s) implemented using a
+bundled set of hardware and software while VNFs utilize cloud resources
+to provide Network Functions through virtualized software modules. PNF
+can be supplied by a vendor as a Black BOX (provides no knowledge of its
+internal characteristics, logic, and software design/architecture) or as
+a White Box (provides detailed knowledge and access of its internal
+components and logic) or as a Grey Box (provides limited knowledge and
+access to its internal components).
+
+* Requirements that equally apply to both VNFs and PNFs are defined as
+ "The xNF MUST/SHOULD/..."
+* Requirements that only apply to VNFs are defined as "The VNF MUST/SHOULD/..."
+* Requirements that only apply to PNFs are defined as "The PNF MUST/SHOULD/..."
