Abstract:
1. A packet transmission device that transmits packets to a receiving-side communication device at a transmission rate corresponding to a measurement bandwidth in order to measure an available bandwidth in a communication system including a plurality of communication devices, the packet transmission device comprising: a processor; a memory storing a program that is to be executed by the processor and, when executed, causes the processor to perform the functions of: a first packet creation portion that creates a first packet including data for bandwidth measurement; a second packet creation portion that creates at least one second packet such that a sum of a data size of the first packet and a data size of the at least one second packet to be created is within a predetermined range including a target value that is set based on the transmission rate; a setting portion that sets a transmission interval for the first packet based on the transmission rate; a first transmission portion that transmits the first packet created by the first packet creation portion to the receiving-side communication device, at a first timing specified by the transmission interval set by the setting portion; and a second transmission portion that transmits the at least one second packet created by the second packet creation portion to the receiving-side communication device, at a second timing that is a timing after the first timing and before a point in time when the transmission interval has elapsed from the first timing.
