Abstract
A method for restoring a communication failure in a network comprises the steps of providing a predetermined order for selection of the links included in the network, searching for an alternative communication path upon a failure in communication occurring in the network, producing, at a first arbitrary node included in the alternative communication path, a first path setup message containing at least information about the number of the paths to be selected in a first link extending from the first node for setting up the alternative communication path, and an identification code of the path that is to be selected at first in the first link for establishing the alternative communication path, transmitting the first path setup message to a second node also included in the alternative communication path and connected to the first node by a second link, for affecting a setup of the connection therein. The second node selects paths with the number specified by the path setup message according to said predetermined order of selection and affects a connection to the paths in the first link according to the order of selection.
