The method of the present invention defines the state parameter field by extending the POF matching domain, and the real-time state parameters of the system can be used as the matching value, thereby realizing flow control based on the state of the switching device, and solving the limitation that POF cannot perceive the real-time state of the forwarding device; in addition, the present invention The invented system further enhances the programmability and intelligence of the SDN forwarding plane flow control strategy.
