<p>The present invention refer to a method for re-routing in ASON, the method is to perform the bridge-connection operation on all bridge-connection nodes while the re-routing connection is established, after the re-routing connection is established and the service has been bridge-connected to the re-routing connection, the first node of the re-routing connection initiates the service switching operation, the switching operation is performed by all of the switching nodes in the re-routing connection, after the switching operation is completed, then the original connection is deleted, thereby the service interruption is avoided, the time of the service interruption may be ignored, since the switching operation is completed instantaneously, the service is sent and received on the original connection without fault before switching.</p> |
