摘要

A propagation delay measuring unit (102) at a transmitting terminal (10) measures by using a propagation delay time measuring packet the shuttle propagation delay time of an intermediate node likely to behave as a bottleneck out of intermediate nodes (12, 13, 14). A transmission rate determining unit (104) determines a data transmission rate based on this measurement result, and a data transmitting unit (100) transmits data at the determined transmission rate.
