<p>PURPOSE:To avoid residence of data and to improve the processing efficiency of the entire system by changing a window size in response to the data processing ratio corresponding to each line so as to keep the transmission data quantity of the entire system to a normal state. CONSTITUTION:Transmission procedure processing means 113, 114 apply each protocol control corresponding to plural lines 111, 112. Then a line monitor means 117 monitors the data processing quantity for the lines 111, 112 and the window size is revised corresponding to each line in response to the data processing ratio to the transmission request processing means 115. Thus, the transmission request processing means 115 sets the window size in response to the size to a data processing ratio for each line at each occasion and the window size is decreased to a line whose data processing quantity is reduced and the window size corresponding to other normal line is increased relatively. Thus, the residence of data is avoided to improve the processing efficiency.</p> |
