The available bandwidth estimating system is provided with a transmitting device and a receiving device, and estimates available bandwidth for a network that connects the transmitting device and the receiving device. The transmitting device is provided with a packet transmission means that transmits a packet train, comprising a given number of packets with packet sizes which are incremented by a certain increment, so that each packet is at even intervals. The receiving device is equipped with a receiving means that receives the packet train from the packet transmission means and calculates the cumulative queuing delay for the packets included in the packet train, and an available bandwidth calculating means that calculates an estimated value for available bandwidth by detecting a point of variation in the overall change of the cumulative queuing delay. |
