Transmission device, available bandwidth estimation device, available bandwidth estimation system, method, and recording medium

摘要

In order to enable to reduce a communication load while maintaining estimation accuracy of available bandwidth estimation being high, a transmission method includes: transmitting estimation packets, a packet size of each of which successively increases, to an available bandwidth estimation device at equal intervals, and, when receiving a signal indicating that a reception interval between the estimation packets at the available bandwidth estimation device starts to increase, stopping the transmission of the estimation packets.
