Abstract: Provided is a protection end node located at an end of a protection path, wherein the protection end node includes a receiver to receive, from a working end node located at an end of a working path, path defect information indicating whether a defect occurs on the working path, a processor to perform protection switching in response to reception of the path defect information and generate path control information used for the working end node to control a connection of the working path based on the protection switching, and a transmitter to transmit the path control information to the working end node.
