<p>A communication system which recover its communication function by itself when a fault occurs and by use of which a highly flexible network is built. A plurality of node devices (12) including data generating sources are connected to a plurality of center devices (11) through communication paths (3) using the ATM technology as if the communication system has a distributed ATM switch function. When the communication path (13) between two node devices (12-2 and 12-3) is cut, the center device (11-2) detects the faulty point, and recovers the communication function by itself by transferring the control of the device (12-2) which is under the control of the device (11-2) to the center device (11-1). The center device (11-2) communicates with the device (11-1) through a local communication means, such as a wide area network (16), etc., because the communication is not possible through the path (13) due to the fault.</p> |
