Virtualisation
Reduces CAPEX, OPEX,Space & Power Consumption. Creates abstractions to enable faster innovation. Creates competitive supply of innovative applications by third parties.
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 mmunity/NFV/367
• 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
