ETSI activities onNetwork Functions Virtualization Laurent VRECK, ETSI GSC-18 Meeting, 22-23 July 2014, Sophia Antipolis, France
What is NFV about? A means to make the network flexible, dynamic, and less dependent on hardware v v Traditional Network Model: HARDWARE APPLIANCE APPROACH Virtualised Network Model: VIRTUAL APPLIANCE APPROACH VIRTUAL APPLIANCES DPI WAN Accel. CG-NAT DPI BRAS BRAS Test/QoE Firewall ORCHESTRATION, AUTOMATION & REMOTE INSTALL STANDARD HIGH VOLUME SERVERS Session Border Controller CG-NAT Firewall • Network Functions are based on dedicated hardware and software • One physical appliance per role • Network Functions are software-based using common and well known hardware • Multiple roles using same hardware
Benefits and Challenges of NFV Benefits • Flexibility to rapidly, dynamically instantiate services in different locations without installing new equipment. • Faster time-to-market for new service introduction • Improving operational efficiency by taking advantage of a homogeneous hardware network platform • Reducing costs through leveraging the economies of scale of the IT industry • Reducing operational costs: less power, less space, improving network monitoring …
Benefits and Challenges of NFV Challenges • Converge IT and Telecom industry to a common understanding of the topic • Achieve (high) performance with portability across different hardware platforms • Achieve co-existence with existing hardware based network platforms • Ensure security& integrity when Managing and orchestrating virtual networks • Integrate multiple virtual appliances from different vendors (on a single HW platform). • Achieve scale benefits through Mgmt&Orchestration automation ETSI NFV ISG was founded to address these challenges
ETSI ISG NFVFounded October 2012 • Global operators + ETSI • Address the needs of network operators, to develop common approaches to Virtualisation • Goal = make NFV a reality in operators networks • define requirements for NFV, • develop architectural frameworks, • identify the gaps in the industry and prepare cooperation with other organizations • Industry Specification Group (ISG) = appropriate model • Quick to set-up • Open membership with small fees to encourage involvement of smaller players • Flexible: allows some (controlled) deviation from the ETSI rules • Binds all participants to ETSI IPR policy • October 2012 : ISG NFV was formed http://www.etsi.org/nfv
ISG NFV 18 months later • 220 companies (including 34 global operators) Has become the “centre of gravity” for the global industry to collaborate on NFV • Intensive work, tremendous effort • 7 plenary meetings so far, 250-300 participants each • ~100 F2F sessions (Draftingmtg, WG mtg, …) • 500+ conference calls • 10 Mailing lists1160 subscribers on the main mailing list • some WG lists “exploded” to 200 + emails/day. Provides an umbrella for the industry to converge requirements, share learning and coordinate wider effort through cooperation with external bodies.

NFV PoC framework 12 NFV PoC Demos @ SDN & OpenFlow World Congress, Düsseldorf,14-17/10/2014 • NFV Proofs of Concept • 21 multi-vendor PoC projects • Minimum 2 vendors and 1 network operator per PoC • Overall +50 vendors and +10 network operators • Addressing NFV E2E concepts (Use cases, Requirements, Interfaces, …) • 80% of NFV use cases covered • Goals • Provide feedback “from the field” • Explore new areas and technology options • Validate assumptions or approaches • Facilitate gap analysis • Help to guide the future NFV ISG activity • Develop Market awareness • Demonstrate NFV capabilities
Second NFV operators White PaperPublished October 2013http://portal.etsi.org/NFV/NFV_White_Paper2.pdf 25 operator signatories Provides operator perspectives on progress made Brings attention to the first outputs and shows a broad operator support Initiates discussion on relationships with other bodies (SDO, Fora). Encourages industry involvement in PoCs Start discussion on the role of Open Source

ISG NFV Release Timeline NFV#5Spain NFV#6Japan NFV#7USA NFV#8USA NFV#9CZ Release ”Freeze” Release Approval & PUBLICATION Release stable,WG final check All WG drafts WG-approved NFVApproval WGApproval Release Maintenance(alignment phase) Progress NFV release OPEN Area Appointment of New WGs/TF officials Ph2 Scope, content ToRs Phase 2Kick-off Ph2 Time plan Finalize Ph 2 plans Structure, Governance Phase 2 inception Phase 2 execution Focus on Phase 2 Focus on Prep. for WG Approval Focus on General Alignment Focus on Final Release • Documents now stabilized for alignment phase(i.e. now under formal Change Control) • Alignment phase: July – November 2014 • Release date: December 2014
What comes in Phase2 • ISG NFV remains the centre of gravity for NFV • Interoperability as major goal • Build on Ph1 results to produce "normative" specifications • Develop cooperation (including Open Source) • Technical Content, Structure, governance proposals ready • Increased Vendors’ involvement • New test framework • Interoptesting • Develop the Proof of Concept framework And more…
A New Open Source Initiative:Open Platform for NFV • Project initiated by members of the NFV ISG leadership that will be coordinated by the Linux Foundation • Create an integrated (SW, HW) open platform • Create an environment for continuous system level validation and integration • Contribute changes to other open source projects used within the platform • provide feedback to the NFV ISG • Build new open source components within the project where needed • Timescales: launch October 2014 to be ready for the NFV ISG release in December.
Conclusions • Tremendous amount of work achieved • Big, well established and very active community • This is just a start • Next step • implementation of these principles in specific Use Cases (eg: 3GPP, BBF, Linux foundation). • Focus on interoperability through normative specs and tests • Cooperate to accelerate
