It downloads courseware list and carries out preliminary download priority sequence, it is corresponding using the courseware list to be downloaded of time further according to various teaching
Courseware data volume size, dynamically the preliminary priority ranking is modified, to obtain that subsequent download can be instructed successively suitable
The final download priority of sequence sorts.
It should be noted that include according to courseware list to be downloaded courseware data volume size setting download priority or
When person corrects preliminary download priority, be referred to the data volume size of history downloading courseware list and the duration of corresponding downloading or
Person's mean time, which is grown, to be determined, for example the time downloaded longer perhaps average time longer then download priority is lower or incites somebody to action
Preliminary download priority is turned down.
Illustratively, than if any A, B, C, D, E five courseware lists to be downloaded, corresponding teaching is respectively using the time
At 9 points in the morning, 10 points, at 14 points in afternoon, 16 points, at night 20 points, the data volume size of corresponding courseware be respectively 10M, 20M,
10M, 100M, 10M:
A:9:00 10M
B:10:00 20M
C:14:00 10M
D:16:00 100M
E:20:00 10M
Priority ranking then is downloaded by instructional blocks of time and courseware data volume size are as follows: A, B, C, E, D.That is, teaching makes
With the more preferential downloading that the time is more early, the smaller more preferential downloading of courseware data volume.
If if reacting above-mentioned download priority height using identifier, the mark of courseware list A, B, C, E, D to be downloaded
Know symbol to be sequentially reduced, the numerical value of identifier is bigger, and download priority is higher, conversely, download priority is lower.
