Problems solved by technology

However, in the prior art, the user needs to manually delete the device information of the network device from the controller. In the case of offline deletion of a large-scale network device, the processing efficiency of the user to manually delete the device information of the network device is very low, and cannot Delete the device information of the network device from the controller in time

Embodiment Construction

[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. Further,...

Abstract

The invention discloses an automatic deleting method and device for offline network equipment. The method includes the steps that a Leader controller receives an offline notification message from a Member controller, wherein the offline notification message carries identification information and offline time information of the network equipment; the Leader controller records the identification information and the offline time information in an offline burn-in table and allocates a burn-in timer for the network equipment; when the burn-in timer exceeds preset time, the Leader controller deletes equipment information of the network equipment and sends deletion information to the Member controller, wherein the deletion information is used for indicating the Member controller to delete the equipment information of the network equipment. According to the method, the offline network equipment is automatically deleted, recovery efficiency of resources is improved, treatment efficiency is improved, and the workload of network managers is relieved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for automatically deleting network equipment offline. Background technique [0002] OpenFlow is a communication interface standard between a controller and a forwarding layer defined in an SDN (Software Defined Network, software-defined network) architecture. The idea of ​​OpenFlow is to separate the control plane and the data plane, and use standard protocols to communicate between them. An OpenFlow network includes a network device (such as an OpenFlow Switch) and a controller (such as an OpenFlow Controller), and the network device and the controller communicate through an OpenFlow channel. Wherein, the controller is used to generate a flow table (Flow Table) according to the user's configuration or a dynamically running protocol, and send the flow table to the network device. Network devices are used to receive the flow table from the controller, and match and ...
