Creates an intelligent network that is more open, programmable, andapplication aware
• a vision in which the network is transformed into a more effectivebusiness enabler
Enables applications to request and change services provided by thenetwork and allow the network to expose network state back to theapplications
What is Software Defined Networks (SDN)?

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?

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
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
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
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.(http://www.etsi.org/nfv)
• NFV blog

Speed up implementation of NFV
Create a carrier grade Open Source Ecosystem
Focus on Open Community which isn’t controlled by one vendor/implementation
Focus on Open Framework to allow the plug and play of different implementations
Try to build upon existing Open Source Foundations
