<p>PROBLEM TO BE SOLVED: To avoid reduction in throughput by suppressing fluctuation in a transfer rate, even when used on an available bit rate(ABR) of an asynchronous transfer mode(ATM). SOLUTION: In this flow control method, a layer 4 processing section 12 uses a data transfer rate S (Ti) at a time Ti, notified from a low-order layer processing section 13, a product between the data transfer rate S (Ti) and a round trip time RTT corresponding thereto and one or more congestion window size cwnd (Ti-1), etc., which is calculated in the past to calculate a congestion window size cwnd (Ti) and to decide a size or a transmission window on the basis thereof.</p> |
