End-To-End Management and Orchestration procedures: The ultimate step towards interoperability (Publication of SOL016 – MANO Stage 3 procedures)2020-08-19 Posted by Rajavarma Bhyrraju, Rapporteur of ETSI GS NFV-SOL 016 2486 Hits
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.
The first released version of ETSI GS NFV-SOL 016 addresses five selected key NFV-MANO procedures, namely on-boarding of a VNF package, instantiation of a network service, termination of a network service instance, scaling of VNF instances in a network service instance and changing the external connectivity of VNF instances in a network service instance.
