Research and comparative analysis of performance test on SDN controller

The emergence of Software Defined Network(SDN) gives the demand of big data and network management a chance. SDN separates the control and forwarding in traditional network through OpenFlow protocol. In the software-defined network, SDN controller is an important integral part that is the core of SDN. In this paper, firstly we summarize the common SDN controller, and choose two popular, wider using open-source controllers(OpenDaylight and ONOS), analyze the implementation architecture and model framework of the two controllers. Then build the controller platform, simulate the underlying topology using IXIA test instruments, Cbench and Mininet to get the performance parameters and furthermore analyze the data.
