Abstract
A device in a line part from a LAN to a WAN includes a plurality of cards which includes a TCP converter relaying two TCP communications. The TCP converter exchanges the number of connections in which data transmission is in progress and the number of connections in which data reception is in progress between TCP converters, receives the total number of connections in which data reception is in progress in an opposite device and an access line bandwidth to a WAN from the opposite device for each TCP connection. A control bandwidth is determined on the basis of the retransmission ratio of data, the total number of connections in which data transmission is in progress and an access line bandwidth to the WAN, and the total number of connections in which data reception is in progress and an access line bandwidth to the WAN of which the opposite device notifies.
