Abstract
The present invention is a transmission system, a path control method, and a transmission device, and is the path control method in the transmission system forming a virtual concatenation group by virtually concatenating each path signal transmitted through a plurality of paths being a logical communication path, which manages an active state and a stand-by state of member paths of the virtual concatenation group and when there is abnormality in any of the member paths in the active state, controls any of the member paths in the stand-by state to the active state in place of the abnormal member path, thereby realizing more flexible and efficient path level redundancy.
