6 ISG NFV Specs All NFV GSs & drafts are public: Published Documents: Drafts: Open Drafts Other SDOs Industry Academia Research Open Source Feedback Loop Feedback loop: An Issue Tracker allows to report and track feedback on NFV Drafts

7 The NFV PoC Framework PoC: Proof of Concept Multi-vendor team working together to implement and demonstrate NFV concepts Launched end 2013 with the first set of NFV deliverables: Use Cases, Requirements, Architecture, Terminology Goals: Look for practical results & get feedback Demonstrate and disseminate NFV capabilities Explore technology options Facilitate gap analysis Help to guide future ISG NFV activities Foster ecosystem and cross-company collaboration

8 Low Barriers PoC team 2+ manufacturers 1+ network operator (member of the ISG NFV). PoC aligned with initial e2e NFV GS: Use Cases Requirements Architectural Framework PoC Proposal according to template Report on outcome and lessons learnt fed back to ISG NFV Call for PoC Proposals open during ISG NFV lifetime

9 Lightweight Process 1. The PoC Team creates a PoC proposal It uploads it to the ISG NFV portal (TST WG section) It sends the link to the PoC mailing list NFV_POC@LIST.ETSI.ORG Subject: [NFV PoC Proposal] + Proposal name The proposal is reviewed If ok, the new PoC is announced to the mailing list If not, feedback is sent back to the PoC team, who can revise the proposal & resubmit 6. The PoC team runs the PoC [THE HARD PART] A public demo is provided 7. The PoC team contributes to the WGs and creates a final PoC Report (as committed in the proposal)

17 SDN and NFV: The Necessary Convergence SDN and NFV are deeply related Though historically separated And they require each other in most cases NFV would be extremely difficult to achieve without SDN Most of the SDN use cases are related to NFV And it has been recognized by the community The EVE005 report in the ISG NFV The technical report of the ONF Architecture WG Fourteen PoC reports have been contributed as evidence to EVE0005 The steps taken by ODL and ONOS Converging views Formal liaisons Community sharing

19 The Concepts Separate functionality from capacity Increase network elasticity Reduce heterogeneity Decouple the control and forwarding functions Gain programmability Abstract infrastructure

21 And the Recursion SDN is inherently recursive Simplify the evolution to NFV-based networks No NFV zero-day The integration with real network attachment points Address different application layers and dimensions Policy reconciliation Multi-tenant environments Multi-domain arrangements Network XaaS

23 Deployment Options The tenant controller defines the forwarding rules for VNFs Service chaining Identity-based services On-demand provisioning The tenant controller is integrated with the OSS BSS becomes a SDN application The BOSS view

24 Intent as Convergence Path Separate hat I a t to do fro eed to do it ho I Go a step forward in abstraction Transparent recursion A common interface for applications To SDN controllers and NFV MANO stacks Integrated development environments Put the human in the loop, as in general software development With a single, integrated entry point Seek for application-network co-design Several on-going activities in ETSI, IETF, ODL, ONF

25 As a Conclusion The ETSI ISG NFV is following a path guided by real experimentation and focused on interoperability Plugtests will soon join PoCs The interaction between SDN and NFV was soon identified as a key issue Well beyond a support for infrastructure virtualization Working in it as part of the technology evolution And in direct collaboration with other bodies Several implementation initiatives active We hope to have them all demonstrated at the ISG Intent-based interfaces as the next frontier for convergence
