A new SDN state inspection firewall system base on OpenFlow protocol is proposed.In this scheme, state tables and shifted flow tables are added into SDN controller and switch, and corresponding state transition rules are formulated on basis of packet type, so firewall is able to inspect SDN network state.SDN stat inspection firewall is implemented on opensource controller Floodlight and Open vSwitch. The performance evaluation result shows that the SDN state inspection firwall can recognize the type of packets, moreover, it achieves the fine-grained access control which present SDN firewall cannot offer. The innovation of this paper is to put forward of inspection firewall fine grained access control on SDN State. by comparing the packet delay and connection establishment speed of the two firewalls, it can be concluded that the firewall system based on state detection has shorter delay time, in general, the connection establishment time takes up less proportion in the whole data transmission. Therefore, in summary, the overall performance of state-based firewall system is better than that of packet filtering firewall system.
