APPARATUS AND METHOD FOR TRANSMITTING DATA AND METHOD FOR DETERMINATION OF TRANSMISSION RATE

摘要

PURPOSE: A data transmission device and a transmission rate determination method are provided to guarantee the transmission rate of cross traffic in a parallel TCP stream. CONSTITUTION: A data transmission device (100) includes a write task (104) and a control task (106). A plurality of write tasks transmits data to a reception device (200) through a network. The control task controls the operation of the write task in a variable transmission operation mode according to the state of a network or a fixed transmission rate operation mode. A variable transmission rate operation mode comprises transmission rate operation mode, a balanced transmission rate operation mode, or a minimum transmission rate operation mode.
