Relying too much on dedicated hardware equipment, resulting in poor flexibility and extensibility of existing communications network, while the new technology application cycle is long, seriously affect the communication operators' interest in deploying. In order to solve these problems, the new network architectureNetwork functionvirtualization(NFV), was proposed. This paper introduces the basic principle and design framework of NFV, proposes a method of constructing virtual network based on NFV, namely achieving routingfunction in the form of software, deploying it to a virtual operating system, and running in the universal server virtualization software in the form of virtual machine, multiple virtual routers and virtual terminal system interconnection constitutes a virtual network, testing and analyzing the transmission performance of the virtual network, realizing to control the transmission performance of the virtual network, create a virtual network that have the transmission characteristics of real network environment to test new technologies.
