Network Functions Virtualisation (NFV) is a network architecture concept that proposes using IT virtualisation related technologies to virtualise entire classes of network node functions into building blocks that may be connected, or chained, together to create communication services.
NFV relies upon, but differs from, traditional server virtualization techniques such as those used in enterprise IT. A virtualised network function, or VNF, may consist of one or more virtual machines running different software and processes, on top of industry standard high volume servers, switches and storage, or even cloud computing infrastructure, instead of having custom hardware appliances for each network function.
The document provides a list of best practices to be used for ensuring smooth migration of Network Elements and Services to NFV environment.
