摘要: The present invention provides a protection switching method of node having communication failure in ring, network. In one embodiment, this is accomplished by checking for loss signal (LOS) at the non-ERPS device or least channel, periodically Continuity Check Message (CCM) both node, wherein CCMs are transmitted from through device, appropriately setting Remote Destination Indication (RDI) bit generated and transmits same via disjoint blocking port towards upon receipt fault notification transmitting fail message on ports ring.
