Method and system for sharing stream media data, and stream media node

Abstract

The invention discloses a method and a system for sharing stream media data, and a stream media node. The method comprises that: the stream media node reports state information per se and queries the state information about other stream media nodes; and the stream media node downloads and / or calls stream media data that the stream media node does not have from the other stream media nodes. The method, the system and the stream media node of the invention, through data sharing among the stream media nodes, ensure that the data of downloading users can be provided for online play users and the data of the online play users also can be provided for the downloading users, so the rate of data sharing among the users can be increased, and the bandwidth load of a server is reduced.

Description

technical field [0001] The invention relates to a P2P technology, in particular to a streaming media data sharing method, sharing system and streaming media node. Background technique [0002] P2P technology belongs to the category of overlay network (Overlay Network), which is a network information exchange method relative to the client / server (C / S) mode. P2P file sharing and P2P streaming media online play are two very important applications of P2P. [0003] The most typical application of P2P file sharing is BitTorrent. When a node in BitTorrent shares a file, it first divides the file into pieces and saves the file and the piece information in a torrent type file. This kind of node is vividly called a "seed" node. When other users download the file, according to the information of the torrent file, they download some parts of the file, and then share the downloaded parts among other nodes that download the file, so as to realize the rapid distribution of the file .

Problems solved by technology

[0011] The first object of the present invention is to aim at the relatively large cost of server bandwidth due to the low data sharing rate between users of the P2P streaming media on-demand system in the prior art, and the inability to play real-time or poor playback effects when downloading streaming video files from P2P files. Can not serve the defect of streaming media on-demand system, provide a kind of streaming media data sharing method that can provide data between downloading users and online playing users, improve streaming media data sharing rate and reduce server bandwidth cost

[0012] The second object of the present invention is to aim at the P2P streaming media on-demand system users in the prior art because the data sharing rate is low to cause the server bandwidth cost to be relatively large, and when the P2P file downloads the streaming media video file, it cannot be played in real time or the playback effect is poor, and at the same time Also can not serve the defect of streaming media on-demand system, provide a streaming media node that can provide data between downloading users and online playing users, improve streaming media data sharing rate and reduce server bandwidth cost

[0013] The third object of the present invention is to aim at the relatively large cost of server bandwidth due to the low data sharing rate between users of the P2P streaming media on-demand system in the prior art, and the inability to play in real time or the playback effect is poor when the P2P file downloads the streaming video file, and at the same time Also can not serve the defect of streaming media on-demand system, provide a kind of streaming media data sharing system that can provide data between downloading users and online playing users, improve streaming media data sharing rate and reduce server bandwidth cost
