Abstract
A communication system includes a source node and an end node of a first working path, a source node and an end node of a second working path, and a source node and an end node of a common path serving as a protection path shared by the first and second working paths. The source node of the common path transfers one of signals received from the source nodes of the first and second working paths to the common path, and the end node of the common path transmits the signal received through the common path to each of the end nodes of the first and second working paths.
