Network communication system and method realizing file downloading

Abstract

A network communication system for downloading the file includes: connecting peer to peer (P2P) server, file server, file description (TPT) server and at least one client via a communication network; the said at least one client downloads the TPT file corresponding to the required file from the said TPT server via the said communication network, queries the seed information corresponding to the said file to the said P2P server, and downloads the required file from the other client regarded as seed in the said communication network and / or the said file server according to the downloaded TPT file. By the said network communication system and method of the invention, the download speed of the client in the communication network is not limited by the server capability and network bandwidth bottleneck. Even though there are a great number of clients which access the network at the same time, the download speed is not affected by it.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a network communication system and method for realizing file download. Background technique [0002] With the continuous development of the communication network, users can obtain more and more useful information from the communication network. Among them, downloading is one of the main ways for users to obtain information from communication networks. At present, the client on the communication network can download the required data from the server through various communication protocols such as File Transfer Protocol (FTP, File Transfer Protocol) or Hypertext Transfer Protocol (Hypertext Transfer Protocol), and its working principle is as follows: figure 1 shown. exist figure 1 Among them, the clients in the communication network, such as client A, client B, ..., client F, can directly communicate with the server through communication protocols such as FTP or HT...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned method of directly downloading data from the server by the client can effectively meet the download requirements of each client when the number of clients connected to the server at the same time is small. When the number of clients accessing the server at the same time exceeds a certain number, the processing capability of the server and the network bandwidth will be bottlenecked, resulting in the slowdown of the download speed of each client, especially when users enjoy the online multimedia services provided by the communication network, such as online When listening to music or watching video programs online, the slowdown of download speed will directly affect the service quality of online multimedia services
