Background
The introduction of Network Function Virtualization (NFV) in mobile core networks has facilitated the reduction of operator networks and brought new convenience for the collection and analysis of operational data. In 10 months 2012, the European Telecommunications Standards Institute (ETSI) organization formally establishes a network function virtualization working group, and aims to define the requirements for implementing network function virtualization and make a system architecture. Under the NFV network, the network function is loaded on the general server in a software deployment mode, so that the effective decoupling of the software function and the hardware load and the sharing of resources are realized. The NFV network has scalability, the general hardware layer can be efficiently expanded, and services borne on the general hardware layer are more flexible in planning, deployment, online, adjustment and other works because special hardware binding is not needed for services borne on the general hardware layer.
