Abstract

The invention provides an address refreshing method and a device. According to the invention, when the port of any node in an intersecting ring combined networking system changes from the reachable state to the unreachable state with the result of the change in the networking topology, a sub-node receiving the address clearing message only clears the address entries corresponding to the ports on the sub-node where the belonging ring is a dominant ring; or rather, when the belonging ring of any local port of a sub-node is a sub-ring, the sub-node does not clear the address entries corresponding to these ports so as to realize selective updating of the address entries of the nodes in a ring combined networking system, and to reduce the network oscillation incurred by the change of ring network topology and to shorten the convergence time of the Ethernet ring network.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to an address refreshing method and device. Background technique [0002] With the rapid development of Ethernet technology, the Ethernet service protection capability has increasingly become an important part of building an Ethernet network. ERPS (Ethernet Ring Protection Switching, Ethernet Ring Protection Switching) technology, as an Ethernet ring protection technology, can realize the fault migration operation within 50ms, and ensure the normal operation of the business by migrating the faulty ring network to the protection state , and the Ethernet node address refresh operation accompanying this process is an important link to realize the protection of Ethernet ring network services. [0003] In the prior art, when the network topology changes due to a ring network failure, all nodes in the Ethernet ring network will refresh address entries, and in this...
