OPERATING METHOD OF NODE FOR ACTIVATING LINK FOR PROTECTION PATH BASED ON GROUPING AND THE NODE

摘要

The present invention provides an operating method of a node for activating a link for a protection path based on grouping, and the node. Provided is the operating method of a first node for generating a first active message for requesting the activation of a first link between the first node and a second node on the protection node for a main path by using a group identifier corresponding to a plurality of nodes extracted based on request messages received from defective nodes on the main path, for transmitting the first activation message to the second node, and for activating the first link by allocating a shared resource for the plurality of nodes according to a response message received from the second node.
