In one embodiment of the invention, according to the corresponding speed of download of each video file burst is downloaded, it is determined that most
The corresponding fringe node of fast speed of download, can be determined by following two modes.
Mode one：According to the corresponding speed of download of each video file burst is downloaded, it is determined that the second most fast predetermined number
The corresponding fringe node of individual speed of download；
Download a video file burst during residue is not downloaded from the fringe node for determining respectively；
The currently corresponding fringe node of most fast speed of download is incited somebody to action, is defined as the corresponding fringe node of most fast speed of download.
Mode two：According to the corresponding speed of download of each video file burst is downloaded, directly will current most fast speed of download
Corresponding fringe node, is defined as the corresponding fringe node of most fast speed of download.
S107：The fringe node determined by downloads the video file burst that the group residue is not downloaded.
In actual applications, above-mentioned N is not less than above-mentioned M, and above-mentioned M is not less than above-mentioned first predetermined number, and above-mentioned first is pre-
If quantity is not less than above-mentioned second predetermined number.
Exemplary, it is assumed that the target video file that client request is downloaded is X, and target video file X correspondences 100 are regarded
Frequency file burst, it is assumed that 100 video file bursts are respectively：X1、X2、X3……X100；Client to video file is parsed
Server sends the video file analysis request for X；Video file resolution server upon receiving the request, is carried out to X
Parsing, by the identification information feedback of 100 video file bursts comprising X to client, wherein, video file resolution server
Video is carried out to resolve to prior art, embodiment of the present invention here does not repeat it.
Assume that above-mentioned division rule is per group of 20 video file bursts, then 100 video file bursts are divided into into 5
Group, it is assumed that first group of corresponding video file burst is X1-X20；Second group of corresponding video file burst is X21-X40；The
Three groups of corresponding video file bursts are X41-X60；4th group of corresponding video file burst is X61-X80；5th group of correspondence
Video file burst be X81-X100.
For each group of 20 video file bursts in above-mentioned five groups, to 8 videos of scheduler dispatches acquisition request
The download address of file fragmentation obtains request.
With first group of corresponding video file burst：As a example by X1-X20, to scheduler dispatches the download address of X1-X8 is obtained
Obtain request.Scheduler determines that 8 fringe nodes (are assumed to be fringe node 1- after download address acquisition request is received
8), the network address of each fringe node in fringe node 1-8 is fed back to into client.Assume video file burst X1 correspondences
The network address of fringe node 1, the network address ... ... of the corresponding fringe nodes 2 of video file burst X2, video file burst
The network address of the corresponding fringe nodes 8 of X8.Then client is from the downloading video files burst X1 of fringe node 1, from fringe node 2
Downloading video files burst X2 ... ..., from the downloading video files burst X8 of fringe node 8.
In actual applications, client can download corresponding video file burst, i.e. video from 8 fringe nodes simultaneously
File fragmentation 1-8 is downloaded from fringe node 1-8 simultaneously.Corresponding video file can also be downloaded from 8 fringe nodes successively
Burst, i.e., first from the downloading video files burst X1 of fringe node 1；After the completion of video file burst X1 is downloaded, then from fringe node 2
Downloading video files burst X2；……；After the completion of video file burst X7 is downloaded, then from the downloading video files of fringe node 8 point
Piece X8.
In actual applications, it is concrete using the still downloading mode successively of downloading mode simultaneously, can be by client according to ought
Front rest network bandwidth (downlink bandwidth) is determined.Such as：When the current residual network bandwidth is more than 5M (million), using simultaneously
Downloading mode；When the current residual network bandwidth is not more than 5M (million), using downloading mode successively.
According to the speed of download of downloading video files burst 1-8, it is determined that the corresponding fringe node of most fast speed of download.
The speed of download for assuming downloading video files burst 1-8 is respectively 2M/s (million/second), 1M/s, 1.5M/s, 0.15M/
s、0.75M/s、1.32M/s、1.75M/s、1.43M/s。
In actual applications, the most fast corresponding fringe node of 3 speeds of download can be first determined, respectively：Edge
Node 1, fringe node 7 and fringe node 3.Respectively a video is downloaded again from fringe node 1, fringe node 7 and fringe node 3
File fragmentation.Assume that the video file burst downloaded from fringe node 1 is video file burst 9, from regarding that fringe node 7 is downloaded
Frequency file burst is video file burst 10, and the video file burst downloaded from fringe node 3 is video file burst 11；Download
The speed of download of video file burst 9-11 is respectively 3M/s, 1M/s, 1.5M/s.Then currently most fast speed of download 3M/s will correspond to
Fringe node 1, be defined as the corresponding fringe node of most fast speed of download.Download what the group residue was not downloaded from fringe node 1
Video file burst X12-X20.
The speed of download for assuming downloading video files burst 1-8 is respectively 2M/s (million/second), 1M/s, 1.5M/s, 0.15M/
s、0.75M/s、1.32M/s、1.75M/s、1.43M/s。
In actual applications, directly by the currently corresponding fringe node 1 of most fast speed of download 2M/s can also be defined as most
The corresponding fringe node of fast speed of download.The video file burst X9-X20 that the group residue is not downloaded is downloaded from fringe node 1.
In actual applications, for above-mentioned five groups of video file bursts, can obtain to scheduler dispatches download address simultaneously
Take request；Can also obtain to scheduler dispatches download address successively and ask, i.e., after the completion of one group of video file burst is downloaded,
Obtain request to the corresponding download address of another group of video file burst of scheduler dispatches again.In actual applications, it is concrete to adopt
Simultaneously request method still request method successively, it is also possible to carried out according to the current residual network bandwidth (downlink bandwidth) by client
It is determined that.Such as：When the current residual network bandwidth is more than 5M (million), using request method simultaneously；When the current residual network bandwidth
During no more than 5M (million), using request method successively.
After the completion of the video file burst X1-X100 of target video file X is downloaded, target video file X has been downloaded
Into.
It should be noted that above-mentioned illustrate by taking downloading video files X as an example, an instantiation only of the invention,
Limitation of the invention is not constituted.
