ABSTRACT:
A connection information takeover unit in an active communication processing apparatus in the system sends connection information and a transmission sequence number of each data to be transmitted to a standby connection recovery device when a connection is established, and a connection information takeover unit in a standby communication processing apparatus retains the connection information and the latest transmission sequence number in a connection information storing unit. A dummy data sending unit of the communication processing apparatus which is switched to active because a failover occurred sends dummy data to a client, and if a transmission sequence number of a reply packet for the dummy data matches with the transmission sequence number in the connection information storing unit, a connection continuity determining unit notifies a communication processing unit that connection can be continued.
