要約
(EN)
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.

(ZH)

接收装置(120)根据到达相应于发送窗口大小的预定基准数的分组所需的分组到达时间生成新窗口大小信息,将其附加到累积ACK分组并向发送装置(110)返回。发送装置(110)以响应于来自接收装置(120)的上述新窗口大小信息决定的发送窗口大小来发送分组。本发明的通信装置(100)在发生传送分组的拥塞之前控制传送分组量。
