<p>PROBLEM TO BE SOLVED: To provide a technology for controlling the bandwidth which reduces fluctuation in UDP data transmission, for assured effective band. SOLUTION: The technology for controlling bandwidth is provided for a communication system environment, in which a device for transmitting data with TCP and UDP is connected via an IP network 101. The device monitors a UDP data transmission amount, while changes the window size of TCP as the UDP data transmission amount increases, so that a bandwidth used for TCP data transmission is controlled, to reduce fluctuations in UDP data transmission.</p> |
