<p>The present invention discloses a method and system for discovering ring network protection information. The method includes: a current node sending node ring network protection information of the current node to other nodes except itself; the current node receiving the node ring network protection information sent by the other nodes, updating or keeping whole network or intra-domain ring network protection information saved by the current node. The system includes a protection information sending module, a protection information receiving module and a protection information processing module; wherein, the protection information sending module is configured to: send the node ring network protection information; the protection information receiving module is configured to: receive the node ring network protection information; and the protection information processing module is configured to: update or keep the whole network or intra-domain ring network protection information saved by the current node. By the present invention, system consumption can be reduced and efficiency of discovering the ring network protection information is improved.</p> |
