Abstract

The invention is suitable for the field of computer networks, and provides a node address table refreshing method and device, a terminal and a storage medium. The address table refreshing method of the node is applied to a target node in an uplink Ethernet ring network, and the target node is configured with a first port and a second port which are located in the uplink Ethernet ring network. The address table refreshing method of the node comprises the following steps: receiving a first topology change message; detecting whether a second port of the target node receives a second topology change message which is the same as the first topology change message; if the target node does not receive the second topology change message which is the same as the first topology change message from the second port, not refreshing the address table of the target node. According to the embodiment of the invention, invalid address table refreshing can be reduced, and the influence on other Ethernet ring networks in the multi-ring networking topology caused by topology change of a certain Ethernet ring network is avoided.

Description

technical field [0001] The application belongs to the field of computer networks, and in particular relates to a node address table refreshing method, device, terminal and storage medium. 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 50 ms by migrating a faulty link to a ring protection link. After the link failure of the Ethernet ring network, the nodes on both sides of the failure will detect the failed link, and send a failure notification message to notify the link failure according to the protocol of the Ethernet protection switching technology. 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 switching of the link. node. [0003] In a multi-ring network topology comp...
