    Operational Benefits

  • 7

    Simplification of network gear installed on premises

    Reduced space and energy consumption

    Less truck rolls and site visits (reduces opex)

    Ability to automate introduction of new services with minimal disruption to existing services

    Customer does not need to be present on site for provision of new network function

    Reduced provision time-months to minutes

    Higher availability- reduced box count reduces hardware components that can fail (less power supplies, fans, cables etc)

    Service agility means not just faster, but new models:

    Tailored services for customers Try-before-you-buy

    Customers can respond rapidly to business drivers:

    Bring up new sites quicker to connect to corporate network

    Fast and seamless adaption to on site changes

    Asset recovery- flexible re-use of software assets

    Summary of Customer Benefits

  • 27 network service providers surveyed (representing 53% of global telecom capex) will deploy NFV at some point with 81% expecting to do so by 2017. IHS Technology NFV Strategies Aug 2016.

    Network Operators Adoption

  • The NFV Open Innovation Story

    Authored & EditedBy BT

    Convened By BTResearch initiated & led by BT

    ETSI NFV Industry Specification Group now has 300 members, ~30 tier 1 carriers.

    The Jul 2014 plenary had 303 participants. 41 multi-vendor NFV Proof of Concepts.

    Informal discussions on cooperation began in April 2012

    At an operator meeting in June 2012 we coined the new term

    Network Functions Virtualisation (NFV).

    We decided to convene a new industry forum, and publish a

    joint white paper to galvanise the industry

    In September 2012 we decided to parent the new forum under

    ETSI called the NFV ISG

    In October 2012 we published the first joint-operator NFV white

    paper as a call to action.

    This paper is widely regarded as the seminal paper heralding this new approach for networks.

    The first NFV ISG plenary session was held in January 2013

    In Oct 2013 the 1st NFV ISG documents were released after

    only 10 months, and a second joint-carrier NFV white paper

    published to provide our perspectives on progress.

    Plans to publish 96 specifications of which ~50 are finalised.

  • The Paradox of a standard high volume server

    Cost of a NFV solution

    Value of NFV is in the openness of the eco-system.

    Standard high volume i.e. portable, software is more important than the

    form factor of the server:

    Different form factors may be more appropriate for different

    locations.

    Virtual Network Functions (Virtual Appliances) should start from

    leveraging the existing IT software eco-system e.g: x86/ARM,

    Linux/Windows, KVM/Vmware.
