What is NFV about?
A means to make the network flexible, dynamic, and less dependent on hardware

Network Functions are software-based using common and well known hardware
Multiple roles using same hardware

Transformation of network hardware
Network Function Virtualization, why ?
Traffic & Service trends Challenges for Network Operators
• Traffic evolutionvoice internet video.
• Services change rapidly, user behaviours as well
• User devices increase in sophistication
• Enterprises want a seamless networked cloud
• Lack of flexibility and agility
• Launching new services is difficult and takes long time
• Complexity
• Inefficiency
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
…

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)
Provides an umbrella for the industry to converge requirements, share learning and coordinate wider effort through cooperation with external bodies.
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 (Drafting mtg, WG mtg, …)
• 500+ conference calls
• 10 Mailing lists1160 subscribers on the main mailing list
• some WG lists “exploded” to 200 + emails/day.

9 Use Cases that should be focussed on for developing future specifications.UCs range from VNF Iaas, VNF aas, VNF Platform aas, to… Mobile core (EPC) and IMS virtualisation, Mobile Base Station virtualisation, and others…
Documents a high-level functional architecture to identify which domain are subject to further specification and innovation and where there is a need for abstraction to enable to abstract the network functions from the hardware.
Not just a list of acronym, helps understanding what is meant by “Virtual Machine” or “Virtual Appliance” or a “Virtual Network Function” so that everyone (coming from IT, Telecom, …) is on the same page when it comes to communication of some of the basics NFV. *
Formalize high level business and technical requirements for virtualization.
“Proof of Concept” Framework: Describes a procedure to encourage growth of the NFV ecosystem through multi-party implementations of Proof of Concept demonstrations (PoCs).
NFV PoC framework
• 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
12 NFV PoC Demos @ SDN & OpenFlow World Congress, Düsseldorf,14-17/10/2014
Second NFV operators White PaperPublished October 2013http://portal.etsi.org/NFV/NFV_White_Paper2.pdf
• 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

Appointment of New WGs/TF officials
• 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
– Interop testing– 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
