With the arrival of big data era,traditional network is difficult to meet the increasing data processing need.In order to solve the problem,software defined network emerge.SDN is a revolutionary improvement compared to the traditional network, it can greatly meet the giant data processing need.However, It is really expansive to build SDN with hardware devices, so we need to develop SDN simulation system.However, the existing simulation systems have so many problems.In this paper, we propose a para-virtual simulation system based on Emulab which can overcome the problems in existing simulation systems.In the paper, we first study the SDN architecture and analyze problems in existing simulation systems.Next we put forward para-virtual SDN simulation system based on Emulab.Thirdly, we build para-virtual simulation system.Then, we carry out verification test on the simulation system we build.Finally, we make a comparison of para-virtual simulation system with the two existing simulation systems(Mininet and the pure physical simulation system).
