Embodiment Construction

[0010] In the present invention, each download task includes 5 states, which are respectively: waiting for download state, downloading state, stop state, download error state, and download completion state; the state of each download task and the conversion between each state are as follows:

[0011] When a download task is added to the download system, the download task first enters the waiting download state, and waits for the download system to start it to enter the downloading state;

[0012] When the system starts a download task, the download task enters the downloading state, that is, the downloading of the content resource is officially started;

[0013] When a downloading task in the downloading state is not satisfied due to certain conditions (for example, the speed is always 0 within a specified time), the system will change the downloading state of the downloading task for the sake of efficiency, so that it will enter again Waiting for download status;

[0014] Du...
