摘要： A method for tracing a communication route through a network coupling a first device with a second device is provided. A first signal is transferred from the first device to the second device to cause a plurality of intermediate devices to report first information concerning the first signal. The first information is processed to identify the intermediate devices as defining the communication route. The intermediate devices are configured so that a second signal, when transferred from the first device toward the second device, causes a subset of the intermediate devices to report second information concerning the second signal. The second signal is transferred from the first device toward the second device. The second information is processed to identify the subset of the intermediate devices as a portion of a sequence of the intermediate devices defining the communication route.

摘要： A control system for a communication network stores a plurality of fault recovery plans that are respectively associated with a plurality of links. The control system processes a first control signal from the communication network indicating that one of the links has a fault, and in response, identifies one of the fault recovery plans that is associated with the one link having the fault and implements the one fault recovery plan. The control system receives a second control signal from the communication network indicating network information, and in response, recalculates the fault recovery plans. The recalculated fault recovery plans implement link-based fault recovery, sub-path based fault recovery, and path-based fault recovery. The recalculated fault recovery plans group links constituents into groups by QoS requirements and assign the groups to back-up routes based on the QoS requirements and the performance of the back-up routes.
