Abstract:
1. An available bandwidth measurement system comprising a transmission device and a reception device that are connected to a network, the transmission device comprising a first transmitter, a first receiver, and a first processor, and the reception device comprising a second transmitter, a second receiver, and a second processor, wherein the first processor is configured to: wherein the second receiver is configured to receive the measurement packets from the transmission device, wherein the second processor is configured to: wherein the first receiver is configured to receive the available bandwidth from the reception device, wherein the first processor is further configured to: wherein the second processor is further configured to acquire a value of a reception interval of the measurement packets, compare the value of the reception interval with the value of the transmission interval, detect a boundary measurement packet, which is the measurement packet for which the value of the reception interval first becomes greater than the value of the transmission interval, and calculate the available bandwidth based on that boundary measurement packet, wherein the first processor is further configured to change the maximum packet size to the packet size of the boundary measurement packet of the previous measurement, change the packet size of the new measurement packet to the packet size of one previous boundary measurement packet in the previous measurement, and change the packet size incremental increase amount to a value that is the result of dividing the packet size incremental increase amount from the previous measurement by the value of the number of measurement packets minus 2, and wherein the measurement packets include a transmission interval value.
