Communication system and method

摘要

Based on a packet arrival time required for a specified reference number of packets corresponding to the transmission window size to arrive, the receiver 120 generates the new window size information, adds it to the accumulative ACK packet, and returns it to the transmitter 110. The transmitter 110 transmits the packets with a transmission window size determined in response to the new window size information from the receiver 120. The communication system 100 of the present invention controls the quantity of packets being transmitted before occurrence of congestion of the packets being transmitted.
