Abstract:
A transfer rate controlling device for controlling a transmission rate of a transmitting terminal when the transmitting terminal multicasts a fixed-length packet to a plurality of receiving terminals in a network where a transfer rate allowed by a path to a receiving terminal is notified to the transmitting terminal by a management fixed-length packet while the transmitting terminal transfers a fixed-length packet to the receiving terminal, comprising:extracting means for extracting transfer rate information from management fixed-length packets which are sent from the plurality of receiving terminals to the transmitting terminal; calculating means for obtaining a parameter instructing a transmission rate of the transmitting terminal by performing a predetermined calculation for a plurality of sets of transfer rate information extracted by said extracting means; and notifying means for notifying the transmitting terminal of the parameter obtained by said calculating means.
