  9. 9. Cycle Time – Faster Instantiation of New or Removal of Old Capabilities/Services • Pre-deployed common pooled hardware • Design for rapid insertion of new or removal of old capabilities/services via software Composition – Faster Innovation to New Features or More Streamlined Functions • Modularity and API vs. today’s monolithic functionality • Easier to re-architect products/services • Agile development to trial features in a sandbox or controlled exposure • Ability to create value-added capabilities while retaining the operational and scale advantages associated with multi-tenant carrier platforms Cost – Providing cost-performance leadership Why are SDN/NFV Important to AT&T? © 2013 AT&T Intellectual Property.

  12. 12. The NFV ISG provides a forum for the industry & operators to collaborate, have common requirements, agree on common approaches, and validate recommendations • Produce a set of requirements/specifications, quick turnaround (4Q2014 Identify technical challenges and scope Encourage Standards as well as Open Source ETSI ISG NFV’s Objectives ETSI ISG NFV
  13. 13. Global operators-initiated Industry Specification Group (ISG) under the auspices of ETSI • >184 companies (Global span: Africa ,Asia ,Europe, Latin America, North America) • 28 Tier-1 carriers (incl mobile) + cable industry Open membership • ETSI members sign the “Member Agreement” • Non-ETSI members sign the “Participant Agreement” • Operates by consensus (formal voting only when required) Deliverables: requirements specifications, architectural frameworks, PoCs, SDO Liaisons ETSI ISG NFV Group 13 ETSI ISG NFV

  15. 15. ETSI ISG NFV We have grown. (159 in NFV#4  184 now) We have moved from identifying the need to specifying the requirements. (White Papers & Frameworks  WG Docs; Identifying gaps in Standards and Open Source) We are focussing on timely completion. (Aggressive timeline for publication.) We are moving our emphasis from identifying requirements to fostering implementations. (Docs  PoCs) We have created proposals for the form of the ISG beyond our initial 2–year charter. (NFV 2.0) Where Are We? © ETSI 2014. All rights reserved15
  16. 16. In the 14 months since the organizing meeting in January of this year : • Published 5 documents - Use Cases, Requirements, Architectural Framework, Terminology, and PoC Framework. • 9 PoC proposals accepted. • 2 drafts in public / open area from SEC & PER Expert Groups • Created easy to navigate websites for access to public material.
