摘要:
An method, apparatus, and computer program product for restoring a failed system in an optical mesh network. A system includes a first light termination element (LTE) and a second LTE. A first node in the network includes an optical switching unit (OSU) coupled to the first (LTE) of the system. A second node in the network includes a second OSU coupled to the second (LTE) of the system. The first node is coupled to the second node by a path. Optical data traffic can be transmitted between the first node and the second node via the path. Upon detection of a failure of the system, the first OSU and second OSU are notified of the failure. A primary role is assigned to one of the first and second OSUs, and a secondary role is assigned to the other one of the first and second OSUs. A primary restoration plan is determined by the primary OSU. Information identifying the primary restoration plan is sent from the primary OSU for effecting the restoration path to restore the system.
