  4. 4. 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

  6. 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

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.
