Abstract
A method for managing a topology of a multi-ring Ethernet and a system thereof are disclosed, and the method includes: a node including a blocked port on the multi-ring Ethernet periodically sending a Topology Find Frame (TF) message along a transmission control channel through an own good port; a node receiving said TF message in the multi-ring Ethernet updating an own topology database according the NODE_LIST in said TF message, writing an own NODE_ID into the NODE_LIST of said TF message, and then forwarding said TF message along the transmission control channel.
