[0044] In order to improve the reliability of the OpenFlow network, multiple controllers may be deployed in the OpenFlow network, and the multiple controllers form a controller cluster. In the controller cluster, one controller acts as a Leader (leader) controller, and other controllers act as Member (member) controllers.
[0045] When a network device is offline, it is necessary to delete the device information of the network device on all controllers in the controller cluster. Based on this, the user can issue a command to delete the device information of the network device on the Leader controller. After receiving the command, the Leader controller will delete the device information of the network device from the Leader controller and notify the controller cluster The member controller in the network device deletes the device information of the network device, and the member controller in the controller cluster deletes the device information of the network device.
