Embodiment
Be explained in detail to the main realization principle of embodiment of the invention technical scheme, embodiment and to the beneficial effect that should be able to reach below in conjunction with each accompanying drawing.
The invention provides a kind of data transmission system, in order to solve in the prior art owing to have transmission bottleneck on the transmission path of point to single-point, cause the data transmission efficiency between the terminal to be restricted, thereby cause the problem of terminal shared access bandwidth waste in access network.As shown in Figure 2, the concrete structure schematic diagram of this data transmission system that provides for the embodiment of the invention, the target terminal 25 and the transmission Control Server 26 that comprise source terminal 21 that data are sent, auxiliary transmission terminal 22～24, data are received, wherein:
After having chosen auxiliary transmission terminal 22, transmission Control Server 26 also needs the information of source terminal 21 is notified to auxiliary transmission terminal 22 and the target terminal of choosing 25, like this, auxiliary transmission terminal 22 and target terminal 25 just can understand self need be from source terminal 21 data download.
Below, illustrate that it needs the function of finishing separately respectively at source terminal 21, auxiliary transmission terminal 22 and target terminal 25:
Behind DTD, can send one to transmission Control Server 26 by source terminal 21 or target terminal 25 and be used in reference to the registration complete message of reportedly being totally lost, transmission Control Server 26 is after receiving this message, and notification source terminal 21, auxiliary transmission terminal 22 and target terminal 25 stop the data of end of transmission are transmitted.
The technique scheme that provides according to the embodiment of the invention as can be known, even the transmission path between source terminal 21 and the target terminal 25 is subjected to the narrower influence of the transmission bandwidth of backbone network, source terminal 21 also can send the data to target terminal 25 by different data transfer paths, so just can make full use of the access bandwidth of source terminal 21; And target terminal 25 also can obtain the data that source terminal 21 provides by different data transfer paths, therefore also can make full use of the access bandwidth of target terminal 25, thereby improve the efficiency of transmission of data greatly.
Need to prove, when data being transmitted based on the transmission means of peer-to-peer network, each terminal can be regarded as each node in the peer-to-peer network, each node can be from other nodes data download, also can provide the data that need be downloaded for other nodes, therefore, the node in the peer-to-peer network both can be used as client, also can be used as server end.Such as, the auxiliary transmission terminal 22 here can be regarded a node in the peer-to-peer network terminal as, therefore auxiliary transmission terminal 22 can be according to the information about source terminal 21 of transmission Control Server notice, direct data download from source terminal 21, and need not the download of carrying out data by transferring in the server.
In the above-described embodiments, transmission Control Server 26 can pass through following manner, determines how to select auxiliary transmission terminal from all auxiliary transmission terminals 22～24:
By the present load state information of transmission Control Server 26 each auxiliary transmission terminals 22～24 of acquisition, can comprise the access bandwidth information of auxiliary transmission terminal in the load state information, available bandwidth information, the current bandwidth information that takies etc.;
The present load state information of each auxiliary transmission terminal 22～24 that above-mentioned transmission Control Server 26 obtains, can but be not limited to initiatively provide according to the predefined time cycle respectively to transmission Control Server 26 by each auxiliary transmission terminal 22～24.
The embodiment of the invention also provides a kind of data transmission method, equally in order to solve in the prior art owing to exist some transmission bottlenecks on the transmission path, cause the data transmission efficiency between the terminal to be restricted, thereby cause the problem of terminal shared access bandwidth waste in access network.The idiographic flow schematic diagram of this data transmission method comprises as shown in Figure 3:
In step 31, can realize choosing by the following mode of choosing to auxiliary transmission terminal:
By obtaining the present load state information of each auxiliary transmission terminal, and auxiliary transmission terminal is selected according to the principle of preferentially choosing the less auxiliary transmission terminal of load condition.Load state information then can be by each auxiliary transmission terminal of reception according to the predefined time cycle, the load state information that active reports, thus realize the present load state information of each auxiliary transmission terminal is obtained.
In the present embodiment, because source terminal, target terminal and the auxiliary transmission terminal of choosing are based on the peer-to-peer network data transfer mode data are transmitted, therefore, source terminal can send the data to target terminal by at least two different data transfer paths, so just can make full use of the access bandwidth of source terminal; And target terminal also can obtain the data that source terminal provides by at least two different data transfer paths, therefore also can make full use of the access bandwidth of target terminal, thereby improve the efficiency of transmission of data greatly.
Correspondingly, the embodiment of the invention also provides a kind of transmission Control Server, and its concrete structure schematic diagram comprises as shown in Figure 4:
Choose module 41, the source terminal that data are sent will be used for when will carry out transfer of data to the data transfer mode of single-point based on point with the target terminal that data are received, in the auxiliary transmission terminal outside source terminal and target terminal, choose at least one auxiliary transmission terminal;
By above-mentioned technical scheme as can be known, because source terminal, target terminal and the auxiliary transmission terminal of choosing are based on the peer-to-peer network data transfer mode data are transmitted, therefore, source terminal can send the data to target terminal by at least two different data transfer paths, so just can make full use of the access bandwidth of source terminal; And target terminal also can obtain data in the source terminal by at least two different data transfer paths, therefore also can make full use of the access bandwidth of target terminal, thereby improve the efficiency of transmission of data greatly.
