OpenFlowClick关键技术的研究

Recently, more and more scientific researchers focus on the process of network information and the advancement of network performance. Because of the constraint of hardware and network architecture it is difficult for researchers to do further research with current network devices. OpenFlow, a new experiment technology, has attracted more and more research attention in recent years. Click, an extensible and programming router, has been accepted by researchers. OpenFlowClick used Click as the routing engine. An OpenFlow element was designed upon Click to control the processing path of per-packet or per-flow in Click. Then OpenflowClick can dynamically implement different functions. This paper first introduces the OpenFlow and Click Technology and related concepts, and then particularly analyses the main technology of OpenFlowClick. At last, through the innovation of OpenFlowClick, I put forward and test the design that use Click in OpenFlow Network, which implement the routing function in OpenFlow Network.
