Abstract

The invention provides a validity detection method and a validity detection device. The validity detection method comprises steps that a request message transmitted by a controller is received, and adetection capability set supported by the controller is carried by the request message; the detection capability set comprises at least a detection type, and the detection type is selected from the detection capability set; a responding message aiming at the request message is transmitted to the controller, and the selected detection type is carried by the responding message, and then the controller can be used to carry out validity detection of flow entries of network equipment according to the selected detection type. By adopting the technical scheme provided by the invention, when the controller is used to issue massive flow entries to the network equipment, the network equipment is not required to carry out the validity detection of the flow entries, and therefore the CPU resources ofthe network equipment are saved, the processing performance of the network equipment is improved, the issuing efficiency of the flow entries is improved, and user experience is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a legality detection method and device. Background technique [0002] SDN (Software Defined Network, Software Defined Network) is a new network innovation architecture, its core idea is to separate the control plane of network devices (such as switches, routers, etc.) Provide a good platform for core network and application innovation. [0003] Among them, the controller and the network device communicate through the management channel, and the controller can generate a flow entry for guiding the network device to process packets according to the user's configuration or a dynamically running protocol, and send the flow entry to the network Devices, and network devices process packets according to the flow entries issued by the controller. [0004] In the traditional way, after the network device receives the flow entry issued by the controller, it first che...
