摘要： A path setting method for setting a backup path corresponding to a currently used path in a ring network using a label switching method includes setting an unused first label as a transmitting label of the backup path corresponding to the currently used path in a first direction; reporting the first label to a adjoining transmission device in the first direction; setting the first label as a receiving label of the backup path in the first direction; setting an unused second label as the transmitting label of the backup path in a second direction; reporting the second label to a adjoining transmission device in the second direction; and setting the second label as the receiving label of the backup path in the second direction, in which the backup path is set when the currently used path is set between two transmission devices.

摘要： A ring network of a multicast label switch path scheme includes a plurality of nodes connected to form a ring. Further, a signal input to a first one of the nodes is branched to be transmitted in first and second different directions to a second and a third one of the nodes through a first working path and a second working path, respectively, in the ring network, the second one and the third one of the nodes defining end points of the first working path and the second working path, respectively, from the first one of the nodes, and a first backup path is set from the second one of the nodes to the first one of the nodes in the first direction, and a second back up path is set from the third one of the nodes to the first one of the nodes in the second direction.
