Embodiment Construction

[0032] In order to make the objectives, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work belong to the protection of the present application.

[0033] ERPS technology is an Ethernet ring network protection technology, which can achieve fault recovery within 50ms by migrating the faulty link to the ring protection link. After the link of the Ethernet ring network fails, the nodes on both sides of the fault will detect the faulty link and send a fault notification message according to the protocol of the Ethernet protection switching tech...

Abstract

The present application is applicable to the field of computer networks, and provides a method, device, terminal and storage medium for refreshing an address table of a node. Wherein, the method for refreshing the address table of the node is applied to the target node in the uplink Ethernet ring network, the target node is configured with a first port and a second port located in the uplink Ethernet ring network, and the method for refreshing the address table of the node includes: : Receive the first topology change message; detect whether the second port of the target node receives the second topology change message that is the same as the first topology change message; if the target node does not receive the first topology change message from the second port For the second topology change message with the same message, the address table of the target node is not refreshed. The embodiments of the present application can reduce invalid address table refreshes, and avoid the impact on other Ethernet ring networks in the multi-ring networking topology when a topology change occurs in a certain Ethernet ring network.

Description

technical field [0001] The present application belongs to the field of computer networks, and in particular relates to a method, device, terminal and storage medium for refreshing an address table of a node. Background technique [0002] ERPS (Ethernet Ring Protection Switching, Ethernet protection switching) technology is an Ethernet ring network protection technology, which can realize fault recovery within 50ms by migrating a faulty link to a ring protection link. After the link of the Ethernet ring network fails, the nodes on both sides of the fault will detect the faulty link and send a fault notification message according to the protocol of the Ethernet protection switching technology to notify the link failure. After each node receives the failure notification message, the RPL (Ring Protection Link, Ring Protection Link) node will open the blocked port and refresh the address table, so as to realize the link switching, where the RPL node refers to the ring protection ...
