The Research And Implementation Of BitTorrent File Distribution System Based On Embedded Linux

With the development of science and technology, people are seeking for higher quality service on the file distribution in large scale , especially after band of network become wider. However , the traditional network model - C/S (client/server) can not break through the bottleneck of the band-width and computing-capacity of the server during the distribution of files in large size. A new network model - P2P is launched. Compared with C/S model, P2P take full use of the band-width and computing-capacity of peers, this model perform well in this way. The BitTorrent file distribution system (B-FDS) is one of those kinds of system. Because of more efficient and more stable, B-DFS has become one of most widely used FDSs today.Based on the original network topology of BitTorrent FDS, a new network topology on embedded system is researched. In general BitTorrent FDS, it use WWW (World Wide Web) as its metafile-searching and resource location, but embedded system is not suitable to do this. So, a new server - Torrent server is set up for this purpose, and the client is simplified.The core of system - Client is designed and implemented on a embedded system. According to the requirement of the Client system, the main-board and its peripheral equipment is chosen. The environment of the Client hard-ware is set up. Compounded with other sophisticated program and technology, the integrated FDS is deployed.The BitTorrent FDS is a try to realize on a embedded Linux system in this dissertation. It is a promotion both in P2P technology and the applications on embedded Linux system.
