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.
