Device for controlling a transmission rate of information includes a reception element receiving an input signal, and outputting received data; a transmission element accepting a transmission frame, transmitting a transmission signal at a first transmission rate set based on transmission control information, and outputting a transmission timing signal indicating completion timing of transmission of the transmission signal; an information extracting element extracting the transmission control information from the received data, and designating a second transmission rate when transmitting the next transmission frame to the transmission element; and a service quality control element changing, upon detecting a second transmission rate smaller than the first transmission rate, an upper limit transmission rate to the second transmission rate or less, changing, upon detecting a second transmission rate larger than the first transmission rate, the upper limit transmission rate to the second transmission rate or less after the completion timing, and generating the transmission frame from transmitted data based on the upper limit transmission rate. |
