Abstract

Embodiments of the present invention provide a file downloading method and server. The method includes receiving a download request sent by a client; assigning an idle token to the download request, and checking the current available bandwidth; if the ratio of the available bandwidth to the total download bandwidth is less than a preset ratio threshold, the The download speed of the token is set as a speed-limited bandwidth; according to the download speed of the token, download the file corresponding to the download request, and release the token after the download is complete; send the downloaded file to For the client, in the embodiment of the present invention, the server allocates a token after receiving the download request sent by the client, and when the ratio of the current available bandwidth to the download bandwidth is less than a preset ratio threshold, the server assigns a token to the client. The download speed of the above tokens is limited, which effectively reduces the possibility of network congestion caused by multiple clients downloading files at the same time, and improves the efficiency of file downloading.

Description

technical field [0001] The invention relates to the technical field of electronic communication, and in particular, to a file downloading method and a server. Background technique [0002] How to control the download speed in the Java design network program From the perspective of Input / Output (I / O), the speed-limiting control techniques are: Assuming that the upper limit of the download or upload speed is m (KB / s), then The time spent to send a fixed byte of data (assuming it is n bytes) is: n / m; assuming that n bytes of data are to be sent now, the theoretical time required should be n / m, and in practice , it only takes t seconds to send n bytes of data, then the sending thread should sleep for n / m-t seconds, thus basically achieving speed control. [0003] However, when there are a large number of simultaneous download requests initiated by clients at the same time, the above-mentioned prior art is likely to cause network congestion when a large number of simultaneous do...
