Abstract

The invention discloses a control method, a controller and a switch. The control method provided by the invention comprises the steps of sending a monitoring request message to the switch, wherein the monitoring request message is used for instructing the switch to monitor a system operation state parameter of the switch and send the system operation state parameter of the switch to the controller; receiving a monitoring response message sent by the switch, wherein the monitoring response message carries the system operation state parameter of the switch; and controlling the switch according to the system operation state parameter of the switch. According to the method provided by the invention, an Openflow protocol is expanded via a message interaction mechanism of customizing the monitoring request message and monitoring the response message, the expanded Openflow protocol is used for achieving real interaction of the system operation state parameter of the switch between the controller and the switch, and thus management efficiency of the controller on an SDN network and operation reliability of the SDN network are improved.

Description

technical field [0001] The invention relates to the technical field of communication control, in particular to a control method, a controller and a switch. Background technique [0002] SDN (Soft Define Network, software-defined network) is a new network innovation architecture. Its core idea is to separate the control layer and forwarding layer of network equipment to achieve flexible control of network traffic and provide core network and application innovation. good platform. The SDN basic network includes a controller and a switch. The software-defined network protocol Openflow is established between the controller and the switch as the signaling channel of the control layer and the forwarding layer. The controller configures and manages the switch through the signaling channel. [0003] At present, the controller can only obtain the operation state of the forwarding layer of the switch through the signaling channel, and cannot obtain other operation state information o...
