Abstract:
1. A method performed by a first node communicatively coupled to a telecommunications network, the method comprising: determining, by the first node, that a transmission path for transmitting a video stream in the telecommunications network is functioning improperly, causing the video stream to be interrupted, the determining further comprising: determining a detected error rate associated with an error in the video stream; determining a type of error associated with the detected error rate; detecting that the detected error rate exceeds a predetermined threshold; switching, responsive to the detected error rate exceeding the predetermined threshold, from a failed optical device to a backup optical device; and if transmission of the video stream in the transmission path continues to be interrupted after switching to the backup optical device, alerting a third node that routes the video stream that is being interrupted and other data different from the video stream that is being interrupted to reroute the other data via an alternate transmission path and to continue to allow transmission of the video stream via the transmission path.
