Abstract
To provide a data transmission device for effectively improving throughput (transmission efficiency) regardless of whether a physical bandwidth in a network varies frequently; the data transmission device for transmitting data to a user terminal via a network and controlling subsequent transmitting operations by correlating delay of a packet pertaining to this transmission with network information includes: a variation detection circuit that detects, on the basis of the delay and the network information, that a minimum value of the delay has increased; and an alteration processing circuit that calculates, when the increase is detected by the variation detection circuit, the increased minimum delay value by using data pertaining to a specific packet, and updating a current minimum delay value with the calculated value.
