摘要: As the number of network services increases, scale and complexity also arise. Software-Defined Networking (SDN) is a new architecture during past few years. OpenFlow celebrated protocol for SDN. It has two characteristics we mostly concerned. First, it provides many match fields to fulfill different strategies. Second, rule table partition allowable. However, these may result in considerable memory space prolonged lookup time.In this paper, propose TCAM-based packet classification method mitigate problem mentioned above. Our includes multiple stages, where only some are compared stage. We refinement further reduce accesses. scheme achieves levels improvements classifier as experimental results show.
