Abstract
A communication path fault restoration system especially applicable to a multiple layered communication network is disclosed, in which spare paths are efficiently used between layers which, at the same time, perform the fault restoration process at high speed. A communication path fault restoration system for a communication network having a multiple layered structure comprises a communication path fault receiver for detecting a faulty path according to the network collection information, a communication path restoration selector for selecting a communication layer and the communication path on the layer for dynamically restoring the fault of the faulty path based on the determination of the information on the faulty path using a predetermined evaluation function, and a communication path restoration processing unit for restoring the fault of the faulty path using the communication path on the selected communication layer.
