What’s the Problem !
Box scaling and Web scaling are worlds and decades apart
Processors stopped getting
faster a decades ago. But …
more transistors per chip =
more processor cores
Need to create SW that
leverages this parallel scaling

What is NFV ?
Network functions virtualization (NFV) is a
network architecture concept that uses the
technologies of IT virtualization to virtualize
entire classes of network node functions into
building blocks that may connect, or chain
together, to create communication services.
NFV relies upon, but differs from, traditional server-
virtualization techniques, such as those used in
enterprise IT. A virtualized network function, or VNF,
may consist of one or more virtual machines running
different software and processes, on top of standard
high-volume servers, switches and storage devices, or
even cloud computing infrastructure, instead of having
custom hardware appliances for each network function.

NFV Development Background
At the end of November in 2012, 13 Tier-one operators (including AT&T, British Telecom, Deutsche
Telekom, Orange, Italy Telecom, Telefonica, Verizon, Vodafone, and CMCC) establish the European
Telecommunications Standards Institute (ETSI) Network Functions Virtualization (NFV) Industry
Specification Group (ISG).
Four years and over 50 publications later, the ISG NFV community has evolved through several
phases, its publications have moved from pre-standardization studies to detailed specifications (see
Release 2 and Release 3) and the early Proof of Concepts (PoCs) efforts have evolved and led to
interoperability events (Plugtests). This large community (290+ companies including 38 of the world's
major service providers) is still working intensely to develop the required standards for NFV as well as
sharing their experiences of NFV implementation and testing.
The NFV enables operators to reduce costs, improve efficiency on management, maintenance as well
as service development, and provide great potential in energy-saving, openness as well as innovation.
These advantages attract operators most.

  • 6. 6 © Nokia 2016 What is NFV ? Network functions virtualization (NFV) is a network architecture concept that uses the technologies of IT virtualization to virtualize entire classes of network node functions into building blocks that may connect, or chain together, to create communication services. NFV relies upon, but differs from, traditional server- virtualization techniques, such as those used in enterprise IT. A virtualized network function, or VNF, may consist of one or more virtual machines running different software and processes, on top of standard high-volume servers, switches and storage devices, or even cloud computing infrastructure, instead of having custom hardware appliances for each network function. Traditional Architecture Virtual Architecture
  • 7. 7 © Nokia 2016 NFV Development Background At the end of November in 2012, 13 Tier-one operators (including AT&T, British Telecom, Deutsche Telekom, Orange, Italy Telecom, Telefonica, Verizon, Vodafone, and CMCC) establish the European Telecommunications Standards Institute (ETSI) Network Functions Virtualization (NFV) Industry Specification Group (ISG). Four years and over 50 publications later, the ISG NFV community has evolved through several phases, its publications have moved from pre-standardization studies to detailed specifications (see Release 2 and Release 3) and the early Proof of Concepts (PoCs) efforts have evolved and led to interoperability events (Plugtests). This large community (290+ companies including 38 of the world's major service providers) is still working intensely to develop the required standards for NFV as well as sharing their experiences of NFV implementation and testing. The NFV enables operators to reduce costs, improve efficiency on management, maintenance as well as service development, and provide great potential in energy-saving, openness as well as innovation. These advantages attract operators most.
