Abstract

The application discloses a ring network protection method and device. The method includes: receiving the first (NR, RB) message by the Owner Node of all nodes in the Ethernet ring protection switching ERPS networking; sending CC messages according to the ability of each node in the ring network carried in the message information, confirm that the ability to send CC messages in the ring network is not the weakest, configure the global outgoing maintenance endpoint MEP on the ports of the two nodes, and determine that the CC message sending cycle of the MEP is the ability of the two nodes to send CC messages The CC message sending period of the weaker node; determine the port configuration and maintenance intermediate point MIP of other nodes in the ring network; and encapsulate the above configuration information in the second (NR, RB) message and send it out. By adopting the embodiment of the present application, the problem that the optimal network self-healing time cannot be achieved 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 adopts 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 m...
