Abstract: Provided herein is a method for realizing time reduction in shared mesh protection, the method including, in a protection path node, in response to a resource being used for a first protection path by a node, receiving a resource use request for setting a second protection path from another node; activating a protection switch through comparison of priorities of protection paths at the resource use request received; and transmitting, by the activation of a protection switch, to a next protection path node a first shared mesh protection message where a revert (RT) message for the first protection path and a protection switch (SF) message for setting a second protection path are multiplexed.
