Network Functions Virtualisation (NFV); Reliability; Report on Models and Features for End-to-End Reliability

 

Standard

ABSTRACT

The present document describes the models and methods for end-to-end reliability in NFV environments and software upgrade from a resilience perspective. The scope of the present document covers the following items:

  • Study reliability estimation models for NFV including modelling architecture.
  •  Study NFV reliability and availability methods.
  • Develop reliability estimation models for these methods, including dynamic operational aspects such as impact of load and life-cycle operations.
  • Study reliability issues during NFV software upgrade and develop upgrade mechanisms for improving resilience.
  • Develop guidelines to realise the differentiation of resiliency for different services.
