Abstract：With the rapid development of Internet technology， emerge in an endless stream new Internet applications， cloud computing， CDN， Open Flow and other new Internet structure is developing， the Internet architecture today's bloated has been unable to meet the growing demand in the network. Therefore， extensive research on next generation Internet architecture is in progress. The Internet architecture can be reformed on the system architecture with IP as the core of the present， also can overturn old ideas， design a system structure is completely independent of the network in order to develop revolutionary style， may be combined with the body. Therefore has the necessity and significance of important for testing and deployment of the next generation Internet architecture. Network testing is the basic method of Internet research， in order to meet the needs of large-scale testing and deployment of a new generation of Internet architecture， network experiment platform needs a high performance， high flexibility， high adaptability to provide test environment. Programmable virtual routers based on network platform， the system construction of high performance， high flexibility， stability， the system supports IP or non IP network architecture based on the use of programmable virtual routers， network topology， and can provide real network load， and real-time monitoring of the entire network performance index. This experimental system to ensure the high performance， high flexibility and isolation system in the underlying hardware and software platform， provides the basic platform and reliable as the experimental system， system application using Web technology， provides a convenient and efficient user experience. The experimental system to organize the centralized solution of the whole system， consisting of a server as the core management all programmable virtual routers. Using virtualization technology and programmable， can adapt to network testing and deployment of Internet architecture of the next generation， and the use of high-speed dedicated packet processing board provides high performance， to ensure reliable network experiment. Programmable virtual routers network experiment system is system of real network environment to test the network architecture， protocol and the deployment of programmable virtual router platform based on.

Key Words：The future Internet； Virtual router； Experimental system； Performance evaluation
