PURPOSE:To identify the accurate connection by adding a connection identifier set by a reception side process to a data and sending the result in sending the data from a sender side process to a receiver side process. CONSTITUTION:When a connection 7 is established, connection identifiers different from each other set independently by the reception side process 1b and the transmission side process 1a are exchanged. Then the transmission side process 1a sends a connection establishing request including the connection identifier set by its own process and the reception side process 1b receives the connection establishment request to send the connection establishment reply including the connection identifier set in its own process. The connection identifier of the reception side process 1b is added to the data transferred by the sender side process 1a and the result is sent, and the effectiveness of the connection 7 is confirmed from the connection identifier received by the receiver side process 1b. Thus, the connection is accurately identified.
