Embodiment Construction

[0044] Referring to FIG. 1 , it is a schematic structural diagram of the P2P downloading system provided by the present invention. include:

[0045] Multiple clients, a redirection server, multiple node servers and an information exchange server.

[0046] Its working principle is:

[0047] Each node server includes a seed information reporting module, which periodically counts the current number of seeds of each shared file and reports it to the information exchange server;

[0048] The information exchange server summarizes the reported information of each node server and pushes it to each node server for storage;

[0049] The client logs in to the redirection server, and the redirection server specifies a node server as the client's home node server; in Figure 1, it is assumed that the home node server designated by client 1 after logging in to the redirection server is node server 1;

[0050] The client sends the query seed request message carrying the download file iden...

Abstract

The method includes steps: client end sends request for querying seed message including carried ID of downloading file to pointed server of home node; the server of home node returns back local seed information, and information of other node servers at network side of possessing the seed; the client end obtains correspongding seed information from other node servers, and downloads segment of file from corresponding client end based on the seed information returned from the said home node server, and other node servers. The invention also discloses a P2P downloading system. The invention raises downloading efficiency of P2P, reduces flux and bandwidth of server.

Description

technical field [0001] The invention relates to network communication, in particular to a method and system for downloading files using P2P (peer to peer) technology. Background technique [0002] P2P downloading technology means that during the process of downloading a file from the server, the client regularly exchanges the client information sharing the file with the server, and the client updates the download source node information at the same time, and downloads the file fragment from the corresponding client sharing the file to the local. Using P2P downloading technology, the mode of obtaining resources from a single server is transitioned to the mode of obtaining resources from multiple points, and sharing its own existing resources; therefore, based on point-to-point technology, P2P downloading can realize file sharing, network communication, file exchange and distributed computing, etc. . [0003] P2P downloading in the prior art is mainly used in the sharing of l...
