Abstract
The present disclosure relates to systems and methods for detection of a failed communication link and rerouting network traffic around the failure. One embodiment of a system consistent with the present disclosure may comprise a communication subsystem in communication with the data network and configured to transmit information to a recipient. The system may also include a confirmatory signal subsystem configured to generate a confirmatory signal. The confirmatory signal may be inserted into a stream of data to be transmitted to the recipient through a first communication path. Upon detection of a disruption in the confirmatory signal, a failover subsystem configured to reroute the stream of network data to be transmitted to the recipient through a second communication path. The second communication path may comprise one or more physical connections in the network that are distinct from the first communication path.
