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 a method and device for automatically deleting network equipment offline, the method comprising: a Leader controller receives an offline notification message from a Member controller, and the offline notification message carries identification information and offline time information of the network equipment ; The Leader controller records the identification information and offline time information in the offline aging table, and sets an aging timer for the network device; when the aging timer expires, the Leader controller deletes the network The device information of the device sends a delete message to the Member controller, where the delete message is used to instruct the Member controller to delete the device information of the network device. In the embodiment of the present invention, automatic deletion of offline network devices is realized, resource recovery efficiency is improved, processing efficiency is improved, and workload of network administrators is reduced.

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 ...
