Data transmitting/receiving method, transmitting device, receiving device, transmiting/receiving system, and program

摘要

In a sending terminal (10), a propagation delay measurement portion (102) uses propagation delay time measurement packets to measure the round trip time to/from an intermediate node of intermediate nodes (12, 13, 14) with the potential of becoming a bottleneck. Based on the results of this measurement, a transmission rate determining portion (104) determines the transmission rate of the data, and a data sending portion (100) sends the data at the determined transmission rate.
