Abstract:
1. A method for managing a topology of a multi-ring Ethernet, comprising: a node including a blocked port on the multi-ring Ethernet periodically sending Topology Find Frame (TF) messages along transmission control channels through ports of the node, wherein when the sending port is not the blocked port, said node writes its own Node Identifier (NODE_ID) into a Node identifier List (NODE_LIST) of the TF message, when the sending port is the blocked port, said node does not write its own NODE_ID into the NODE_LIST of the TF message; a node receiving any of said TF messages in the multi-ring Ethernet updating the topology database of said receiving node according to the NODE_LIST in said TF message, writing its own NODE_ID into the NODE_LIST of said TF message, and then forwarding said TF message along the transmission control channel.
