COMMUNICATION SYSTEM, COMMUNICATION DEVICE, CONTROL DEVICE, CONTROL METHOD, AND PROGRAM

摘要

In a case where it is determined whether or not a signal transmitted from a node currently in use to a standby node has been disconnected on the communication path of the signal, and it is determined that the signal has been disconnected, the communication system is switched to a network path used by a client device and the standby node for data communication. Thus, it is possible to perform early the operation of switching to a network path required for another node to substitute the processing that was being performed by a certain type of node.
