Abstract
In a bandwidth estimation device, a measurement unit measures a measurement time from reception by a receiver of a first packet of a packet train including a plurality of packets that are sequentially transmitted from a transmitter via a communication line to reception by the receiver of a last packet of the packet train, An estimation validity determination unit compares the measurement time with a threshold time predefined based on performance of the receiver or characteristics of the communication line to determine whether a valid estimate of an available bandwidth of the communication line can be made. In response to the estimation validity determination unit determining that a valid estimate of the available bandwidth can be made, an estimation unit estimates the available bandwidth of the communication line based on an amount of data in the packet train and the measurement time.
