Method and system to prevent false restoration and protection in optical networks

Systems and methods are described in which circuitry of a first controller of a first node receives a first signal indicating an optical loss of signal within the first path. Circuitry of a second controller of the first node on the first path within a transport network generates a second signal ind...

Summary:Systems and methods are described in which circuitry of a first controller of a first node receives a first signal indicating an optical loss of signal within the first path. Circuitry of a second controller of the first node on the first path within a transport network generates a second signal indicating a failure within the first path. The first controller accessing a network topology database determines that restoration of the first path would be ineffective due to there being no alternate path, and signals a second node downstream in the first path with the second signal indicating the failure within the first path, and a third signal indicating that restoration of the first path would be ineffective due to there being no alternate path.
