Embodiment in the present invention, those of ordinary skill in the art are obtained under not making creative work premise
The every other embodiment obtained, broadly falls into the scope of protection of the invention.
File is generally divided into some pieces and is downloaded by P2P software, for program request or live carry out P2P
During download, in order to ensure the fluency of played data, need sequentially to download according to the order of data block.
Now, when same channel or program are played out by multiple stage client, if under the most in that same order
Carry data block, then a client cannot get the data self not having from another client,
Then just cannot be carried out more data interaction between two clients, it is necessary to all obtain data from server.
Like this for downloading two clients of same resource, the data user rate between them will
It is greatly reduced.
In order to solve the problems referred to above, the embodiment of the present invention provides a kind of dispatching method downloading data, such as figure
Shown in 1, described method includes:
101, when client downloads same data with opposite end, the data download condition of opposite end is obtained.
In P2P network environment, partial data is divided under several data blocks carry out respectively by P2P software
Carry.When the same data of multiple stage client downloads, establish data interaction between these clients and link,
First can obtain, from other clients, the data self do not downloaded when a client needs to download data
Block, if client just can be downloaded from server when other clients the most do not exist the data block self do not downloaded
Data block.Therefore, in the dispatching method of the downloads data provided in the embodiment of the present invention, when client and
When same data are downloaded in opposite end, it is necessary first to client obtains the data download condition of opposite end.
102, judge whether opposite end comprises the data block self do not downloaded according to data download condition.
After client gets the data download condition of opposite end in a step 101, it is necessary to according to right
The data download condition of end judges whether comprise the data block self do not downloaded in opposite end, thus according to judgement
Result determines the mode of self subsequent download data block.
103, if the determination result is YES, then from opposite end, obtain the data block self do not downloaded.
When judging to comprise in opposite end the data block self do not downloaded in a step 102, client is the most permissible
From opposite end, directly obtain the data block do not downloaded, and need not obtain, from server, the data block do not downloaded,
Such that it is able to directly carry out data interaction without trunking, and the client not connected by server
The impact of quantity, improves the efficiency of client downloads data.
If 104 judged results are no, then from the data block that self does not downloads, randomly choose a data block
It is downloaded.
When judging in a step 102 not comprise, in opposite end, the data block self do not downloaded, client is just
A data block can be randomly choosed from the data block that self does not downloads be downloaded, so that opposite end
When downloading the data block that client randomly chooses, it is possible to directly obtain this data block from described client.
This mode for multiple stage client when program request or live same video resource particularly important, due to visitor
Family end is using P2P program request or during live video, in order to ensure the fluency of video playback, need according to
The order of data block is sequentially downloaded, if when multiple stage client program request or live same video, they
Obtain data block the most in order, be difficult to the downloading data block that there are differences the most between which, i.e. one
Some data block of client downloads, other clients have the most generally downloaded same data block, or one
Platform client downloads some data from server, and other clients are same owing to cannot obtain from opposite end simultaneously
Data, just can only obtain these data from server, so will result between client node occur
The problem of data block collision, causes a client just cannot get self from another client and does not has
Some data, thus cause and between client, cannot be carried out more data interaction, it is necessary to all from server
Obtain data.And in opposite end, do not found the data self do not downloaded by client by the embodiment of the present invention
After block, break the mode of original downloading data block in order, from the data block that self does not downloads
Randomly choose a data block to be downloaded so that opposite end is energy when the data block randomly choosed described in downloading
Enough directly obtain this data block from this client.When more client is at program request or live same video
During resource, the method according to the embodiment of the present invention processes, and will be greatly improved client and obtain video
Efficiency, improves the utilization rate of data between client.
The dispatching method of the download data that the embodiment of the present invention provides, when client downloads same number with opposite end
According to time, it is possible to by client obtain opposite end data download condition, judge according to described data download condition
Whether opposite end comprises the data block self do not downloaded, if the determination result is YES, is then obtained from from opposite end
The data block that body is not downloaded；If judged result is no, then randomly choose from the data block that self does not downloads
One data block is downloaded.And in the prior art, generally for program request or live carry out under P2P
During load, in order to ensure the fluency of played data, need sequentially to download according to the order of data block.
If same channel or program are played out by multiple stage client, downloading data block the most in that same order,
So one client just cannot get the data self not having soon from another client, then two
More data interaction is just cannot be carried out, it is necessary to all obtain data from server between client.Therefore with
The defect phase that in prior art, data acquisition when being downloaded program request or live data is inefficient
Ratio, the embodiment of the present invention enables to multiple stage client and downloads the data block that opposite end does not has respectively, thus
Can not download from server and directly obtain from opposite end when other clients need certain data block, greatly
Improve greatly the data interaction between client, improve the efficiency that data are downloaded.
In order to preferably the method shown in above-mentioned Fig. 1 be understood, thin as to above-mentioned embodiment
Changing and extension, the embodiment of the present invention will be with two clients (table scale be that another table scale of client is as opposite end)
Carry out program request or live time download data instance, each step in above-mentioned Fig. 1 is described in detail.
When client downloads same data with opposite end, client needs to obtain the data download condition of opposite end,
Determine according to the data download condition in opposite end and self need by which kind of mode to be obtained not download data.?
When obtaining the data download condition of opposite end, client can have the central server of nodal information by record
Obtaining the position diagram of opposite end, institute's rheme diagram is used for recording the download situation of each data block in partial data,
Such as can utilize bit to represent the download situation of a data block in partial data, when it
When value is for " 0 ", represents that described data block is not downloaded, when its value is " 1 ", represent described data block
Download, according to the numerical value of position diagram just can get which data block be downloaded which data block not by
Download.Described central server does not preserve the data needing to download, and simply is responsible for sending out by client node
Cloth data message, they want to share what data to allow central server know, allow and need its other clients
Its sharable data resource downloaded by end node.
In P2P network environment, partial data is divided under several data blocks carry out respectively by P2P software
Carry, and when the same data of multiple stage client downloads in P2P download environment, each client all can

Body, it is simply that determine which which data block is downloaded according to the numerical value of each data block of record in the diagram of position
A little data blocks are not downloaded.Owing to client is identical with the number of the data block of opposite end, therefore client can
Download situation with the data block according to opposite end to determine whether to there is self non-downloading data block.
The numerical value of the download situation of 8 data blocks of representative of the position diagram record of such as client is
11000000, the numerical value of the download situation of 8 data blocks of representative of the position diagram record of opposite end is also
11100000, when client starts to download the 3rd data block, find the 3rd data block in opposite end
Numerical value is 1, illustrates to comprise the data block self do not downloaded in opposite end, then client can be directly from opposite end
The 3rd data block of middle acquisition, obtains the 3rd data block without from server, thus improves data block
Download efficiency.
When client starts to download fourth data block, find fourth data block in the diagram of position, opposite end
Numerical value is 0, then do not comprise the data block self do not downloaded in explanation opposite end, then client is ensureing self
In the case of playing normally, do not continue to download fourth data block in order in original mode, but at random
Never the data block downloaded select a data block (such as the 7th data block) be downloaded.Work as institute
Stating after the 7th data block of client downloaded, opposite end fourth data block is likely to have downloaded,
So that client directly can obtain when downloading fourth data block from opposite end, and opposite end exists
Directly can obtain from client when downloading the 7th data block.Client is not downloaded by random download
Data block, breaks original mode being downloaded according to data block order, makes multiple stage client play
Do not resynchronize download during same resource, thus do not have and between client, can not find difference download data
The situation causing each client cannot directly carry out data interaction occurs.
When carrying out program request or live client is the most simultaneously, each client is all according to the embodiment of the present invention
Method when not downloading data at random with the order of data block, more enable between client
Farthest from opposite end, get the data block self do not downloaded, and need not download from server, keep away
