There is a module used when uploading / downloading through the file server 200.

The file transfer status display module 107 has a high probability that the speed will fluctuate every moment because the file that the user wants to download is downloaded from several places (for example, including several peers and sometimes a file server). It displays the transfer speed and capacity of the file currently being downloaded to the user so that they can know the status of the file being downloaded (e.g., the total downloaded file size and the estimated time required).

Next, the P2P-Grid file sharing device of FIG. 3 illustrates a torrent protocol-based P2P-Grid file sharing device built in the file server 200 according to the present invention.

The device is a program incorporating a torrent engine and operates in a file server 200 of a web hard company.

Specifically, the torrent engine module 201, the announce communication module 202, the middleware communication module 203, the file upload module 204, and the file download module 205 are included.

The client may or may not be provided with information to download and seed the file via the announcement web server. In order to download the file, the client first loads the torrent file and connects with the URL or IP information of the announce web server described in the file. You get the peer's IP for the file and the piece's piece information. Then the download is practical. To seed (distribute) a file, the client first creates a torrent file for the file to be distributed by the client.In this case, the information of the announce web server is provided by the middleware server. After getting piece information of, it is created. When the generated torrent file is transmitted to the announce web server, the announce web server registers the torrent file and updates the information so that other users can download it.

The client authentication module 402 should not be accessed by any client because the announce web server provided by the web hardware company must be operated privately due to the nature of the service. To this end, it is necessary to provide a function of restricting access based on IP or user ID, and the client authentication module 402 performs the function.

The middleware communication module 403 performs the function of delivering the announcement web server information (IP and URL information) when the middleware server creates a torrent file through the announcement web server. It also provides the ability to suspend and delete files when you don't want to see files from the Announce web server. When performing these functions, basic authentication (e.g., valid user, valid authority, etc.) is provided. To perform.

The client communication module 303 stores data (eg, authentication request, announcement server information request, information request for upload / download file, file server IP, file capacity, file name, etc.) requested by the client program through the network. Perform the function for processing.

The database communication module 304 stores information about a file (file server IP, file name, file size, etc.) in a separate database. The database communication module 304 stores a database of a web hard service company. In conjunction with this function, it provides the user with the necessary information (eg, announce server IP, file name, file size, etc.).

In addition, the database 500 refers to a database set up for a service by a web hard service company, but a database may be added if necessary. Information about the Announce web server (IP. Capacity, torrent file storage path, etc.), peer information (IP. Connection history, history of uploaded / downloaded files, etc.), file information ( File name, file size, file owner, file hash value, etc.).
