Some extra ONAP terminology

This terminology will be used through the mapping tables provided below.

Function

NFVs, VFCs, VDUs, and even Services are represented by the generic node type onap.nodes.Function.

Motivation:

  • To reflect and highlight the fact that from the orchestration perspective, all these classes are the same – TOSCA templates backed by artifacts
  • Making the model more lightweight, getting rid of redundant 
  • Allow for composition constructs more flexible than the basic ETSI VDU-VNF-Service cage. As a service provide, I may want to compose my own VNFs of other VNFs, Services that make use of other Services, etc.


Functions: Interface & Implementation

ONAP Data Model represents VNFs, VDUs, VFCs as the Interface Type combined with either the Implementation Topology or the Implementation Image

Interface Type

A VNF/VFC/VDU interface type is a TOSCA node type derived from onap.nodes.Function. For the sake of better readability, this node type may be have the metadata field ‘type’ and values [VNF, VDU, VFC]. The interface type defines properties, capabilities and requirements of the VNF/VFC/VDU.

Implementation Topology

An implementation topology of a VNF/VFC/VDU is a TOSCA topology template. It contains TOSCA node templates interconnected through TOSCA relationship/capability pairs or TOSCA relationship templates. The component node templates are normally of types derived from onap.nodes.CP, onap.nodes.VL, onap.nodes.Container, and onap.nodes.Function. An Implementation Topolgy must also include a TOSCA substitution_mappings construct that refers to an Interface Type and “wires” the properties, requirements and capabilities of the Interface Type to those of the internal nodes. In addition, the Implementation Topology may also include TOSCA groups and policies that target internal nodes.

Implementation Image

In its simplest form, a function does not have an Implementation Topology. Instead, its Interface Type specifies a TOSCA deployment artifact, like a VM or Docker image. This artifact is sufficient for the orchestrator to launch an instance of this function. This artifact is called an Implementation Artifact and effectively represents the SwImage element from the ONAP Info Model. A Function with an Implementation Image represents the VDU element of the Info Model.

Comparison





A VNFD is a deployment template which describes a VNF in terms of deployment and operational behaviour requirements. It also contains connectivity, interface and virtualised resource requirements.

  1. A TOSCA node type derived from tosca.nodes.nfv.vnfd (VNF interface type)
  2. A TOSCA topology template with substitution mapping to the VNF Interface Type #1 (VNF implementation template)


1)     A TOSCA node type derived from onap.node.Function (VNF interface type)

2)     A TOSCA topology template with substitution mapping to the VNF Interface Type #1 (VNF implementation template)


NFV: the node type is strictly bound to the VNFD element


ONAP DM: the node type is generic; the same node type is used to represent VNFs, VFCs, VDUs, and, in the future, Services. See Generic Node type onap.nodes.Function for all components
