When a failure is occurred in the Internet or a connection between a computer system and an Internet provider, a reconnection is performed automatically, and data are resent. Hence, a restoring operation can be made easily. Further, even when long data are re-transferred, a reliability can be ensured. When a receiving computer and the Internet provider are disconnected and reconnected, a sending computer receives an old IP address and a new IP address of the receiving computer, and compares the received old IP address and an old IP address stored in a connection information storage. When the IP addresses are matched, the data are re-transferred to the receiving computer by using the received new IP address.
