After a year long effort, ETSI has just released the first specification of a Yet Another Next Generation (YANG) data model for NFV descriptors, ETSI GS NFV-SOL 006. The specification is based on ETSI GS NFV-IFA 011 and ETSI GS NFV-IFA 014, and can be found on the ETSI server, with the corresponding YANG files can be found on the Forge website. The specification covers VNFD, PNFD and NSD. It enables on-boarding of NFV descriptors on YANG-based MANO functions, in a standard way. The flexibility and the ability to define network services, and to do it quickly is the true strength of the specification.
