ABSTRACT:
It is an object to provide a flow control method in which a packet round trip time is not excessively calculated out and its performance is not unnecessarily deteriorated even at the time of continuously connected packet transfers through relays of a plurality of receiving terminal devices. This method is directed to a flow control method in which the delivery of packets are carried out through relays of a plurality of receiving terminal devices. The method is comprised of steps (S501-S517) for acquiring a packet round trip time for every pair of neighboring terminal devices in a path of the delivery, a selection step for selecting one from the acquired round trip time in accordance with a predetermined standard, and a step (S518) for calculating a packet transmission rate on the basis of the selected round trip time, so that the round trip time of each receiving terminal device is measured and the transmission rate is calculated in accordance with the measured result. Thus, a packet round trip time is not excessively calculated out, and data transmission performance can be improved.
