Abstract

The invention discloses a looped network protecting method and device. The method includes the steps that all Owner Nodes in an ERPS networking are protected and switched through the Ethernet, and first (NR, RB) messages are received; according to capacity information for sending CC messages of each node, carried by the messages, in a looped network, port configuration global outward MEPs of two nodes weakest in capacity for sending the CC messages in the looped network are determined, and it is determined that the CC message sending period of the MEPs is the CC message sending period of the node, weaker in CC message sending capacity, of the two nodes; port configuration MIPs of other nodes in the looped network are determined; configuration information is packaged in second (NR, RB) messages and sent out. Due to the adoption of the looped network protecting method and device, the problem that optimal network self-healing time cannot be reached in the prior art can be solved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a ring network protection method and device. Background technique [0002] The fault detection mechanism of G.8032 uses the CC (Continuity Check) defined in Y.1731 or IEEE 802.1ag to perform link bidirectional forwarding detection, which can locate the fault point and detect whether the fault is unidirectional or bidirectional. When used for protection switching, the default transmission period of the CC frame is 3.33ms (that is, the transmission rate of 300 frames per second). G.8032 judges the state of the link through the message notified by Y.1731, and makes corresponding processing. Such as figure 1 As shown, each node in the ring network is configured with an outgoing MEP (Maintenance association End Point, maintenance end point) of the same service instance on adjacent nodes for judging the state of the link. The control message types of G.8032 mai...
