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

• Network Functions are based on dedicated hardware
  and software
• One physical appliance per role

• Network Functions are software-based using common
  and well known hardware
• Multiple roles using same 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
5
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

6
Benefits and Challenges of NFV
Challenges

• Converge IT and Telecom industry to a common
  understanding of the topic
• Achieve (high) performance with portability
  across different hardware platforms
• Achieve co-existence with existing hardware based
  network platforms
• Ensure security integrity when Managing and
  orchestrating virtual networks
• Integrate multiple virtual appliances from
  different vendors (on a single HW platform).
• Achieve scale benefits through MgmtOrchestration
  automation
• ? ETSI NFV ISG was founded to address these
  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

ISG NFV 18 months later
Has become the centre of gravity for the global
industry to collaborate on NFV

• 220 companies (including 34 global operators)

• 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.

Provides an umbrella for the industry to converge
requirements, share learning and coordinate wider
effort through cooperation with external bodies.

First 5 ISG NFV deliverablesOctober 2013
Available from ETSI site free of charge
http//www.etsi.org/nfv
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).
10
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 _at_ SDN OpenFlow World Congress,
  Düsseldorf,14-17/10/2014

Second NFV operators White PaperPublished
October 2013http//portal.etsi.org/NFV/NFV_White_
Paper2.pdf
25 operator signatories

• 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

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

15
A New Open Source InitiativeOpen 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.

16
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
