<p>When a plurality of nodes determine the communication rate prior to point-to-point communication, there is reduced the difference in the throughput between a node which has determined a high communication rate and a node which has determined a low communication rate. For this reduction, a communication rate recording unit (11) of a slave node (1) records the best communication rate (the maximum communication rate) of the slave node (1). A communication rate setting unit (12) determines the communication rate between the slave node and the master node at the start of the data communication, and sets a control communication rate equal to or lower than the determined communication rate, on the basis of the maximum communication rate and the determined communication rate. A communication rate control unit (13) controls the communication rate by using a hold buffer (14) so that it may not exceed the control communication rate set by the communication rate setting unit (12).</p> |
