BIDIRECTIONAL RETRIEVING TYPE SELF-HEALING METHOD

摘要

PURPOSE:To shorten the fault restoring time in a self-heating method where each node autonomously and dispersedly restores in a network. CONSTITUTION:The nodes 11 and 12 of a faulty terminal first serve as senders to broadcast a retrieving message 15 including the information necessary for the relief of both up/down-paths. Then both nodes 11 and 12 serve as the choosers to receive the message 15 that had the collision somewhere and returned and to select the bypasses independently of each other.
