<p>PROBLEM TO BE SOLVED: To provide a method for improving a transmission efficiency by adjusting a transmission interval of a credit to an optimum value automatically in the flow control of the credit of data transfer in digital transmission. SOLUTION: This transfer device at its receiver side is provided with a buffer idle monitor circuit 151, a credit transmission interval storage circuit 154, and a credit transmission interval update circuit 156 controlling a credit transmission interval of a credit transmission interval storage function. Every time a credit is sent, the idle buffer is monitored and when any idle buffer is in existence, the credit transmission interval of the credit is decreased so as to make transmission of credits dense and when no idle area is in existence in the buffer, the credit transmission interval is extended so as to make the credit transmission thin thereby controlling the transmission interval of credits optimizingly.</p> |
