New release: Data models for resource templates to foster interoperability between VIMs and NFVOs/VNFMs

2020-08-19 Posted by Hiroshi Dempo, ETSI GS NFV-SOL 014 rapporteur, NEC 8276 Hits

The ETSI NFV Industry Specification Group (ISG) has completed the initial release of ETSI GS NFV-SOL 014 titled "YAML data model specification for descriptor-based virtualised resource management". The specification focuses on a set of YAML-based data models used between NFVO and VIM (Or-Vi reference point), and also between VNFM and VIM (Vi-Vnfm reference point) for exchanging information on virtualised resources and their management. The work item and resulting document addresses specification gaps in the area of virtualised resource management and aim at enhancing the integration and interoperability of VNFM and NFVO with VIM solutions.

In the ETSI NFV specifications, interfaces and information models for the Or-Vi and Vi-Vnfm reference points have been specified in ETSI GS NFV-IFA 005 and ETSI GS NFV-IFA 006 respectively. Based on those specifications, the objective of ETSI GS NFV-SOL 014 is to define a set of YAML-based data models for representing information exchanged over these reference points as input and outputs to perform virtualised resource management. The descriptor-based virtualised resource management assumes a type of VIM which supports templates declaring parameters, requirements, lifecycle and composition of sets of virtualised resources.

End-To-End Management and Orchestration procedures: The ultimate step towards interoperability (Publication of SOL016 – MANO Stage 3 procedures)

Following intense technical work, ETSI NFV has just released ETSI GS NFV-SOL 016, the first stage 3 specification of NFV-MANO procedures in NFV Release 2 addressing interactions across several NFV-MANO functional blocks and/or interfaces. This specification builds on the ETSI NFV-MANO API specifications ETSI GS NFV-SOL 005, ETSI GS NFV-SOL 003 and ETSI GS NFV-SOL 002 which have defined the mandatory and optional operations and data attributes per individual NFV-MANO interface. As these specifications are focusing on individual interfaces, it is left up to the operator or the integrator to stitch together the information across different NFV-MANO interfaces to realize the NFV-MANO procedures involving interactions across several NFV-MANO functional blocks and/or interfaces, also referred to as end-to-end procedures. This might lead to various interpretations of how the end-to-end NFV-MANO procedures should work. ETSI GS NFV-SOL 016 defines procedures for selected key NFV-MANO procedures with the target to improve interoperability end-to-end.

Steady progress on Release 3 and Release 4 work

The ETSI NFV community met for its twenty ninth plenary meeting (NFV#29) from 17 to 21 February at the Home of NFV, ETSI Headquarters, in Sophia-Antipolis, France. This time, the plenary meeting took place amidst the unfortunate situation, the Coronavirus outbreak that has hit so many countries and seriously impacted standardization work, and life in general almost worldwide. Consequently, some of our delegates were not able to travel and attend the meeting physically. Our best wishes to all of you all around the world who have been impacted by the outbreak, "wishing you a good and quick recovery".

Addressing the impact of this outbreak on the handling of the plenary meeting, ETSI provided outstanding support, as usual, by enabling remote access for participants that could not travel. Furthermore, the ISG and working group officials made a very good job of adapting the schedule and working procedures to facilitate the active participation and contributions of the remote delegates. As for those of us that had the opportunity to attend the plenary physically, ETSI had provided a very useful new facility: the delegates participating F2F could check-in for the first time by scanning their meeting QR code using a check-in station in the ETSI lobby. check in

All in all, despite the circumstances, the plenary meeting was once again a success. All working groups made steady progress in most of the work items that are currently being developed as part of the Releases 3 and 4.
