Abstract: A method of performing shared mesh protection switching in a sharing node is provided. The method includes: receiving a request message from a first terminal node, having detected a signal failure of a working path; copying the request message and forwarding a request message to an adjacent node on a first protection path of a plurality of protection paths; determining whether a sharing resource is available; transmitting, if a sharing resource is available, an available message to a second terminal node forming a pair with the first terminal node; and receiving a response message from the second terminal node, having received the available message from all sharing nodes on the first protection path.

Abstract: A protection switching unit and a method of performing protection switching of the protection switching unit are provided. The method includes steps of detecting a fault that has occurred at a working path of a network; opening a first switch that is connected to the working path and closing a second switch that is connected to the protection path of the network; and maintaining a connection state of the first switch and the working path and a connection state of the second switch and the protection path, when a fault that has occurred at the working path is restored.
