[0082] Example
[0083] Combine figure 2 As shown in the schematic diagram of the process of changing the sending rate with time, the data transmission method provided by the embodiment of the present invention includes: the data sending end sends data to the data receiving end at the initial sending rate, and periodically determining the parameters for evaluating the transmission link , And adjust the sending rate according to the current parameter value. As these parameters are updated periodically, the sending rate is adjusted periodically accordingly.
[0084] The parameters used to evaluate the transmission link include the maximum receiving rate, packet loss rate, and RTT. Among them, the maximum receiving rate refers to the maximum value of the receiving rate determined on the premise that the packet loss rate does not exceed the upper limit of the packet loss rate. For example, periodically measure the receiving rate and update the maximum receiving rate. Optionally, th...
