TW202244747A - A peer-to-peer file sharing technology in web browsers without installing additional extension or plug-in - Google Patents

Abstract

A peer-to-peer file sharing technology without additional extension or plug-in has been proposed only to use web browsers for file transfer and data sharing. File providers can use the upload form provided on the web page to split each complete file into file fragments of smaller units as pre-processing of point-to-point file fragment transmission. Then, file requesters can select the sharing file listed on the web page to obtain file fragments from the file provider and other file requesters. In the web browser, the required file fragments are collected to restore the complete file to realize the peer-to-peer file sharing technology of the web browser. This technology enables file providers and other file requesters to request resources between web browsers. Under the same Internet operating experience, users can achieve large file transmission and data sharing with the best sense of convenience, stability, and reliability.

Description

An application technology for peer-to-peer file sharing in web browsers without installing extension software

The present invention is based on the web browser (Web Browser), by the hypertext markup language (HTML) and the HTML page interactive programming language, interacts with the web application program (Web Application) in a full-duplex communication mode, and realizes web browser and Peer-to-peer file sharing between web browsers. That is, users do not need to install additional extensions or software packages, and users do not need to change the Internet experience. They can use web browsers to share peer-to-peer files. It is suitable for immediate access to very large files. An occasion for transmitting and sharing requirements.

The data transmission of super-large files is carried out through peer-to-peer technology. In the previous technology, users need to install the file transfer application program developed by peer-to-peer technology in order to carry out the file including the complete file of the file provider and divide it into smaller units. Fragmentation; and the file requester requests the required file fragmentation from the file provider and other file requesters through the file transfer application program, and reassembles it into a complete file.

Realize peer-to-peer file sharing in the web browser. In the previous technology, the user needs to install the extension function in the web browser. Through the combination of the extension function on the web browser and the file transfer application, the web browser is used as a file The proxy operation interface of the transmission application is presented in the form of Hypertext Markup Language (HTML) to be close to the user's operation experience in the web browser.

Use peer-to-peer file sharing (Peer-to-peer File Sharing) technology to transfer very large files, and when supplying the needs of a large number of file requesters, it can avoid excessive reliance on single-source file providers and overcome the limitations of a single source transmission bandwidth.

The present invention provides a web browser (Web Browser), which uses hypertext markup language (HTML) and HTML page interactive programming language, and uses a full-duplex communication method to communicate with network applications. Use the program (Web Application) to interact, so that users can transfer and share data of very large files between web browsers. The web application includes a set of file management core modules for processing Functional modules related to file disks, including functions such as adding files, deleting files, listing files, searching files, obtaining file information, obtaining disk capacity information, releasing disk cache capacity, etc.; a core module for file fragmentation , a functional module used to deal with file fragmentation, including file fragmentation that divides a complete file into smaller units, verifying whether the hash value of the file fragment bit data matches the integrity verification code of the file fragment, accessing the file A list of fragment holders, merging file fragments to restore complete files, etc.; and a set of core modules that can perform peer-to-peer communication applications.

The present invention provides an application technology that does not need to install extension software to realize peer-to-peer file sharing in web browsers. The peer-to-peer communication application core module of the network application program can establish full-duplex communication when the web browser is connected to the network application program. In the connection environment, use the HTML page interactive programming language in the web browser to establish the service function of the client-server model including the server and the client, and use it as a point-to-point communication environment. When the user requests the bit data of the file fragment, the full-duplex communication connection environment of the web application program will obtain the point-to-point connection information of the file fragment holder, and through the use of the established in the web browser The peer-to-peer communication environment to transfer the bit data of file fragments.

Please refer to Fig. 1 and Fig. 2, the present invention provides a kind of application technology that does not need to install expansion software to realize the peer-to-peer file sharing of web browser, this technology is that user 10 operates web browser 11 to send communication to web application program 12 Command 13, the webpage application program 12 sends a communication response 14 to the web browser 11 after receiving the communication command 13, and the response content includes hypertext markup language 15 and HTML page interactive programming language 16. The HTML page interactive programming language 16 includes function copies of the file management core module 17, the file fragmentation core module 18, and the point-to-point communication application core module 19, so that the web browser 11 can operate various core modules through the function copies All functions on the group. The functions of file management core module 17, Including adding files, deleting files, listing files, searching files, obtaining file information, obtaining disk capacity information, and releasing disk cache capacity. The functions of the file fragmentation core module 18 include dividing the complete file into smaller units of file fragmentation, verifying whether the hash value of the file fragmentation bit data matches the integrity verification code of the file fragmentation, and accessing the file fragmentation There is a list of owners, and the file fragments are merged and restored to a complete file. The functions of the peer-to-peer communication application core module 19 include registering with the web application program 12, obtaining and removing the peer-to-peer connection information of the web browser 11, starting and ending the peer-to-peer connection to other web browsers 11, And try to restore the connection when it is abnormally interrupted, send communication commands to other web browsers 11 and respond to communication commands, and send data to and receive data from other web browsers 11 .

After the web browser 11 completes receiving the hypertext markup language 15 of the communication response 14, the HTML page interactive programming language 16, and related function copies, the web browser 11 will start to establish a full-duplex communication connection 20 with the web application program 12 , and use the function copy of the peer-to-peer communication application core module 19 to establish a peer-to-peer communication environment 21 capable of interacting with other web browsers 11 in the web browser 11 . The user 10 operates the web browser 11, obtains file information through the file management core module 17, uses the file fragmentation core module 18 to obtain detailed information of the file fragments on the specified file, and a list of holders of the file fragments, Through the full-duplex communication connection 20 of the web application program 12, the point-to-point connection information of the file fragment holder can be obtained, and the point-to-point communication environment 21 can be used to send a communication command to the file fragment holder to perform file fragmentation The bit data resource request, after obtaining the required file fragmentation, is restored and stored as a complete file by the function of the file fragmentation core module 18.
