Strategic Networking Paradigms & SDN

• NFV and SDN are highly complementary, they are mutually beneficial but not dependent

on each other (NFV can be deployed without SDN and vice-versa)

• SDN can enhance NFV performance, simplify compatibility, facilitate operations

• NFV aligns closely with SDN objectives to use commodity hardware and standard IT

orchestration and management techniques

Slide 5

2011-2012 Developments

Standard high volume servers have sufficient

packet processing performance to cost

effectively virtualise network appliances. •The hypervisor need not be a bottleneck.

•LINUX need not be a bottleneck.

•TCO advantages are scenario specific but

expect significant benefits.

•Plus a significant reduction in energy

consumption.

IN-CONFIDENCE

ETSI NfV Industry Specification Group (ISG)

• Network-operator-driven

– Initiated by 13 carriers

– Consensus in the white paper

– a Network Operator Council offers requirements

– grown to ~20 network operators so far

• First meeting mid-Jan 2013

> 150 participants from > 50 firms

• Second meeting mid-Apr 2013

– 284 participants from > 105 firms

• Open to non-ETSI members.

• ETSI NfV collaboration portal

– white paper, published

deliverables

– how to sign up, join mail lists,

etc

http://portal.etsi.org/portal/server.pt/co

• Deliverables

– Common requirements &

framework

– White papers identifying gaps

and challenges

– as input to relevant

Key Takeaways

• BT and other network operators have proven NFV feasibility via proof of

concept test platforms

• Network Functions Virtualisation likely to dramatically change the telecom

landscape and industry over the next 2-5 years.

• Network operators and vendors have identified numerous “fields of application”

spanning all domains (fixed and mobile network infrastructures)

• Significant CapEx/OpEx benefits leveraging the economies of scale

• Emerging virtual network appliance market

• Novel ways to architect and operate networks, spawning a new wave of

industry wide innovation

• Opportunities for new market players
