Network Functions Virtualisation (NFV) Release 3; Management and Orchestration; Network Service Templates Specification
Network Service Templates Spec
Scope and Field
This revision of NFV-IFA 014 continues the development of the specification as part of the NFV Release 3.
This edition will add functional requirements and specification of the information model to support the Release 3 features, and it will extend the scope of the former Release 2 edition summarized hereafter:
This Work Item will develop a specification for describing Network Service meta-data requirements and meta-data templates used to decribe Network Services.
Examples of Network Service meta-data templates are Network Service Descriptor, VNF Forwarding Graph Descriptor, Virtual Link Descriptor and PNF Descriptor.
This work item will build from the information captured in the MAN Group Specification documents related to information elements.
Standardized meta-data templates are required for Network Services to:
•describe the relationships between NS and VNFs and/or connectivity to PNFs that are part of the NS, along with dependencies and other constraints, such as those imposed by the scope of the MANO GS MAN 001,
•describe the NFV infrastructure resource requirements for a NS in a service provider environment
•describe NS operational behaviour within the scope of NFV including NS lifecycle events (eg. scaling, upgrading).
Deliverable for this work item will be an normative GS document addressing:
-Requirements for the structure and format of the various NS meta-data templates,
-A consistent meta-model, describing the NS properties and resource requirements building,
-A consistent meta-model, describing the NS networking properties and resource requirements building,.
The output of this work should be used as formal requirements for extensions into normative specifications developed by other SDOs.
This revision of NFV-IFA 014 will address the Release 3 candidate features listed in Annex B of the Release 3 Definition (v0.10.0). Where needed, it will continue the previous version to enhance and complete the specified Release 3 features.
This revision will reflect the maintenance performed to NFV Release 2 documentation and of already specified Release 3 features.
