When the reply rate changes, the process proceeds to step 305. When the reply rate has not changed, the process proceeds to step 305 to determine that the reply mode of the downloaded data ACK does not need to be adjusted.

Step 305, the adjustment module 107 adjusts the reply mode of the download data ACK according to the judgment result. In the preferred embodiment, the adjustment module 107 adjusts the reply mode of the download data ACK to reply one download data ACK every N download data packets. When R is an integer, N is equal to R. When R is a decimal, N is equal to R and is incremented by one. For example, suppose the download packet speed (100M bps) is 100 packets per second, and the speed at which the upload link returns the downloaded data ACK (1M bps) is only enough to return 30 download data ACKs per second. The module 103 calculates that the ACK reply rate of the downloaded data download data is R is 3.3, and the integer is incremented by one, which is 4, and the adjustment module 107 adjusts the reply mode of the downloaded data ACK to reply for downloading 4 download packets. A download data ACK, in this way, the upload of the download data ACK can be completed at the same time as downloading the data package, so that the data download speed reaches the full load speed of 100M bps.
