Abstract
The present invention provides a trouble releasing system wherein, in operation of an ATM logic IP subnetwork, interruption of communication by a stop of an address solution server is prevented. When a currently used NHS,which performs address solution in a logic IP subnetwork stops a server operation because of a trouble thereof, a standby NHS control unit,in a standby NHS,issues an instruction for change-over to a server operation, and consequently, the standby NHS,operates as a server for address solution. Further, an NHC control unit,in an NHC,retrieves an address of the standby NHS,registered in a server address database,and causes the standby NHS,to switchably perform communication of an address solution request.
