<p>PROBLEM TO BE SOLVED: To prevent reduction in throughput.SOLUTION: A transmission buffer 14 stores a transmission packet output from a packet processing unit 15 and outputs the transmission packet to a communication unit 11 according to control of a buffer control unit 16. A buffer monitoring unit 13 continuously monitors free space of the transmission buffer 14 and outputs a result of the monitoring to a window size change unit 12. The window size change unit 12 changes a window size notified of by another communication device by using an ACK packet, on the basis of the free space of the transmission buffer 14. The packet processing unit 15 generates a new transmission packet and outputs it to the transmission buffer 14 while taking the changed window size as the upper limit.</p> |
