Abstract
The apparatus 10 is set on the line between the first and second computers 1,2 which respectively communicates by a protocol, such as TCP, having a flow control. The delay between the first computer 1 and a position, at which the apparatus 10 is set, is less than the delay between the position and the second computer 2. The apparatus 10 sends and receives a packet to/from the computers 1,2. The apparatus 10 transfers to the second computer 2, a data packet sent from the first computer 1 and being larger than a maximum data amount notified by the second computer 2. The apparatus 10 transfers, to the first computer 1, a data packet sent from the second computer 2, but does not transfer, to the first computer 1, an ACK packet sent from the second computer 2. The apparatus 10 generates, instead of the second computer 2, an ACK packet for a data packet sent from the first computer 1 and then sends the ACK packet to the first computer 1. Therefore, in a case that a large delay section having exists in the line between the computers 1 and 2, it is possible to perform a high speed communication on one way by only setting one apparatus 10.
