Problems solved by technology

There are several ways to transfer files in the Internet environment: File Transfer Protocol (FTP, File Transfer Protocol), Hypertext Transfer Protocol (HTTP, HyperText Transfer Protocol), etc., but these transmission methods will cause server and bandwidth bottlenecks, and the system cost is very large. Energy expansion is not easy; another file transfer solution is point-to-point (P2P) publishing technology, such as BitTorrent, although it solves the bandwidth bottleneck problem of large-capacity file transfer, but due to the change of seed nodes and files Incomplete and incorrect files often occur

Embodiment Construction

[0017] This document release system consists of the following parts:

[0018] 1) Publisher: Send media files, playback arrangements, and other content to designated terminals. Sent through the seed server, that is, the real file content is on the seed server.

[0019] 2) Receiver: Receive files and messages. The received files can be used as seeds to provide forwarding services.

[0020] 3) Point-to-point server: responsible for providing point-to-point services, such as login, logout, node list, message delivery, file delivery, etc.

[0021] The point-to-point server is the central service point that controls all the connection between the publishing end and the receiving end, and it is also a bridge to connect to the database. All terminals (including the publishing end, receiving end) and the database must interact through the point-to-point server. The point-to-point server is a service program, a background program without interface requirements, and the operating envi...

Abstract

The issuance end up loads files to be issued to seed server, and commits information including file list, terminal etc. needed to issue to point-to-point server. The point-to-point server obtains tor information of file from the seed server. Then, the point-to-point server sends the tor information of file to the receiving end of file. After receiving tor information, the receiving end looks up available subsections of file, and executes downloading on nodes in LAN first based on data provided by tor information. If nodes in LAN have no usable file, then the receiving end connects seed server to download subsections of file till all subsections are downloaded completely so as to assemble a correct file. The invention uploads the file to be issued to seed server in order to guarantee that the file is existed, integrated, and correct on the seed server. The invention ensures reliability and stability of file transmission, i.e. 100% transmission guarantee.

Description

technical field [0001] The invention relates to a method for issuing files in the field of computer communication, in particular to a method for issuing files using point-to-point technology. Background technique [0002] In the network multimedia publishing system, users need to transmit large-capacity media files in the network. In order to ensure the quality of playback, it can only be done by saving the media files on the advertising machine. There are several ways to transfer files in the Internet environment: File Transfer Protocol (FTP, File Transfer Protocol), Hypertext Transfer Protocol (HTTP, HyperText Transfer Protocol), etc., but these transmission methods will cause server and bandwidth bottlenecks, and the system cost is very large. Energy expansion is not easy; another file transfer solution is point-to-point (P2P) publishing technology, such as BitTorrent, although it solves the bandwidth bottleneck problem of large-capacity file transfer, but due to the cha...
