Abstract: A method, an apparatus and a system for interconnected ring protection, relates to the communication field, realizes the protection of the interconnected ring network using a narrow bandwidth, and improves the bandwidth utilization rate. The method comprises: a first intersection node in an intersection node group receiving an cross-ring service, the first intersection node determining an off-ring node of the cross-ring service on a second ring according to service information of the cross-ring service; and if the first intersection node does not communicate with the off-ring node of the cross-ring service on the second ring, and the first intersection node is not the last intersection node, the first intersection node forwarding the cross-ring service to a second intersection node.

Abstract: A method includes determining a transmission path. The method includes determining, by a first node, a first candidate path group that includes at least one first candidate path. when the first candidate path group includes at least two first candidate paths, The method further includes selecting a first path from the at least one first candidate path according to a preset first rule based on node information of each of the first candidate paths in the first candidate path group. The method further includes determining that the first path is a transmission path and when a source node of the first path is the first node, or determining that the second path is the transmission path when the source node of the first path is a second node, where the second path is a reverse path of the first path.
