Abstract
The invention discloses a system and a method for document distribution based on internet. The system comprises a central server, at least one associated server and at least one client, wherein the central server is connected with the associated server so as to receive the documents from the associated server or send the documents to the associated server; the associated server is connected with the at least one client so as to send the documents to the client or receive the documents uploaded by the client; and the client is connected with the associated server. The invention has the following advantages: the distribution path is simple, greatly relieves the pressure of the server for the documents distribution and improves the efficiency and reliability for the documents distribution, and supports continued uploading and downloading at the interruption point, so that the documents uploading and downloading can be paused or continued.
Description
Technical field
The invention belongs to network communications technology field, relate to a kind of document distribution system and method based on the Internet.
Background technology
Along with popularizing of network, some information based on traditional media (CD, tape etc.) (video display, music etc.) are gradually with the media of network as propagation.These Internet resources often occur with bigger document form, download for everybody.Conveniently, efficiently and reliably obtaining this class network file is problem that is worth exploration of current network technology.Along with the terminal quantity that connects network sharply increase and the variation of network configuration with complicated, problems such as traditional centralized file distributing pattern is faced with retractility, it is sudden to connect, controllability and reliability, so press for and study new application model.
Traditional centralized file distributing pattern is shown in figure one.When a bigger file will be distributed by the user that network disperses to the position, system can upload to the file that will issue on Web server or the ftp server, notifies the user from this central server file in download then.Server has been born whole uploading (server transmits file to download person) expense, and its disposal ability and transmission rate are the bottlenecks that influences file distributing speed.Along with increasing of number of users, the obtainable speed of download of each user will reduce, simultaneously the server machine of also can delaying because of load is excessive.Therefore a lot of servers all can limited subscriber number and speed of download, brings inconvenience to the user.
Also develop the distribution method of with good grounds Service coverage distributing network file in recent years, it as application number 200910084776.5 patent documentation, though this method has been alleviated the expense and the pressure of director server, but increased a large amount of intermediate servers, simultaneously also make the distribution path of file become loaded down with trivial details, be unfavorable for distributing the raising of speed.Number of patent application is that 200810103137.4 patent documentation discloses the pressure that method that a kind of timesharing downloads alleviates server, but this method has also limited the time of downloading when alleviating server stress, this and user think that the wish of download is disagreed in real time, can not satisfy the development in future needs.

Embodiment two
The described method of present embodiment adopts data transport service end (DTS) and transfer of data client (DTC) two ends composition, and DTS is made up of with a plurality of related DTS a center DTS, center DTS comprise information such as the address of relevant DTS and port.
As shown in Figure 2, during the DTC upload file, the related DTS under earlier file being uploaded to, this related DTS is uploaded to center DTS to file again, center DTS reaches each related DTS to file according to related DTS tabulation again, and related DTS sends to following DTC to the file of oneself again.DTC can specify some or all recipients, appointed recipient can select to accept or refuse the file that other people send when upload file.This method provides carries out the function that repeated downloads is judged to identical file, the control methods of local file and server file is not to only depend on file name and size to compare, also to extract content and compare, local whether consistent to determine fast with the file of server.As to two of the same name, with the size, when file of the same type compares, first file is randomly drawed the packet that size is specified in a position, again another file is extracted the packet of same position same size, this individual again packet is compared, can repeat this action repeatedly, confirm whether be duplicate packet.Concrete transmitting step is as follows:
One, tentation data transmission client A1 will upload also distribution of document and " upload .txt ":
1, DTC (A1) reads the file relevant information of " uploading .txt ", is packaged into the listed files packet and is uploaded to related DTS (A).
2, related DTS (A) increases listed files data (comprising descriptors such as file name, size, sender), and the listed files data are sent to center DTS, after center DTS obtains the listed files data, initiatively " upload .txt " to DTC (A1) demand file, DTC (A) is uploaded to center DTS to file.
3, after center DTS finishes receiving, listed files data and file data are distributed to relevant DTS, after related DTS is received listed files data and file data, the listed files data are distributed to all DTC under it.
Two, tentation data transmission client B1 will receive the file " download .txt " of distribution:
DTC (B1) sends the request of agreeing to receive " downloading .txt " file to related DTS (B), and related DTS (B) sends file data to DTC (B1).
Embodiment three
The described method of present embodiment can be to uploading and speed control is carried out in download, as shown in Figure 3, can manage each DTS at DTS_ADMIN end (being the server admin end), set the speed that following DTC uploads, downloads, guarantee that bandwidth obtains rationally, maximum using.For guaranteeing uniform data, the visit of all DTS is managed and is dispatched by DTS_ADMIN.When DTS request visit DTC, DTS_ADMIN is unified to put into buffer queue, is obtained one by one by a thread again, just carries out visit DTC order at last, and the result is adjusted back to each DTS.
Embodiment four
As shown in Figure 4, we can adopt P2P (peer-to-peer, point-to-point) mode, allow each work station as receiving client, again as sending service end, so more can alleviate the pressure of server end greatly simultaneously.
Here description of the invention and application is illustrative, is not to want with scope restriction of the present invention in the above-described embodiments.Here the distortion of disclosed embodiment and change are possible, and the various parts of the replacement of embodiment and equivalence are known for those those of ordinary skill in the art.Those skilled in the art are noted that under the situation that does not break away from spirit of the present invention or substantive characteristics, and the present invention can be with other forms, structure, layout, ratio, and realize with other elements, material and parts.
