Abstract
Failure to identify an accurate rising position of a queueing delay alone has led to the inability to ensure estimation precision. An available bandwidth estimation method comprises: transmitting a packet train constituted by packet pairs arranged at equal intervals, each of the packet pairs comprising two packets of the same size arranged at a zero transmission interval, with the packet size of the packet train increasing at a constant rate; receiving the packet train; calculating an observation delay of the packets included in the received packet train; calculating a serialization delay on the basis of the reception interval between the two packets constituting each packet pair included in the received packet train; removing the calculated serialization delay from the calculated observation delay, thereby calculating a queueing delay; and estimating an available bandwidth on the basis of the calculated queueing delay.
