The technology of software defined networking, which introduces the concept of centralized control, provides a new idea for the intelligent network.Meanwhile, it also introduces the control delay in the end-to-end transmission delay of the service.Industry network has extremely high requirements on real-time and reliability.Thus, the balance between real-time and flexibility is one of the key points in the application of SDN technology in such communication networks.The article combines the advantages of two types of flow table release mode, and through the method of topology determination , the threshold module is used to realize the flexible and fast switching of the flow chart release mode, which improves the real-time and reliability of the network.
