In my understanding, ETSI will focus on the information model only . It will not describe the detailed protocol and data models, which may be the work of other SDOs, e.g., IETF, OASIS and etc., if we'd like to use the protocols/languages from these SDOs. >checking out the web for background information > (couldn't find the cited ETSI references), I found this nice comparison > table.

But the scope is not huge actually. We will not work on all the NFV data models, rather, we only focus on three parts: NFV Service, VNF Forwarding Graph and VNF. To define the YANG data models of the three elements is our ultimate goal. > > > Tom Taylor > > > Basic Concept > > SDN Separate control and data, centralize control > and programmability of network > > NFV Relocate network functions from dedicated > appliances to generic servers > > Target Location > > SDN Campus, data center / cloud > > NFV Service provider network > > Target Device > > SDN Commodity servers and switches > > NFV Same > > Initial Applications > > SDN Cloud orchestration and networking > > NFV Routers, Firewalls, gateways, CDN, > WAN accelerators, SLA assurance > > New Protocols > > SDN OpenFlow > > NFV None > > Formalization > > SDN Open Networking Foundation (ONF) > > NFV ETSI NFV Working Group > _______________________________________________ > OPSAWG mailing list > [email protected] > https://www.ietf.org/mailman/listinfo/opsawg _______________________________________________ OPSAWG mailing list [email protected] https://www.ietf.org/mailman/listinfo/opsawg
