Provided are a data transmission method, device and system, the method comprising: utilizing a preset reordering window size to adjust the lower limit value of an original receiving window, and acquiring the lower limit value of a current receiving window, the lower limit value of the original receiving window being the packet sequence number of the next data packet that a receiving terminal expects to receive; comparing the lower limit value of the current receiving window with the lower limit value of the original receiving window; if the lower limit value of the current receiving window is greater than the lower limit value of the original receiving window, then updating the lower limit value of the original receiving window to be a breakpoint value, the breakpoint value being the packet sequence number of the first not yet received data packet not smaller than the lower limit value of the current receiving window; and transferring to a receiving layer the data packet having the packet sequence number smaller than the breakpoint value. An embodiment of the present invention reduces the time delay of data packet transfer, and reduces data packet jitter during transmission. |
