Abstract
The invention discloses a method, a system and equipment for sharing files. The method comprises the following steps of: creating a seed file for a multimedia file to be shared, and sending the seed file to a server; sending a sharing message to a user side which shares the multimedia file; and transmitting the multimedia file to the user side through a P2P network when the user side selects to download the multimedia file. The sharing of the multimedia file in the method is based on the P2P network, so the pressure on the server when a plurality of users synchronously download is relieved, the user quality of service is improved, and network paralysis cannot be caused when the server breaks down; moreover, the notification and the download during the sharing of the multimedia file are automatically finished by equipment of the user sides and do not need to be manually operated by the users; therefore, the sharing of the file is convenient and quick.
Description
Technical field
The present invention relates to network communication field, particularly a kind of file sharing method, system and equipment based on P2P (peer-to-peer, point-to-point).
Background technology
Along with the digitized development of electronic product; For example digital camera, DV etc.; These products produce increasing multimedia file; The user also has with other user usually and carries out the mutual demand of multimedia file, to reach the purpose of common appreciation except oneself is appreciated these multimedia files.But, when mutual these multimedia files, because the restriction of the network bandwidth, and the restriction of multimedia file size, be difficult to usually share larger-size multimedia file through network quickly and easily.
The inventor finds in the research process to prior art; On the user uploads onto the server multimedia file through HTTP (HypertextTransfer Protocol, HTTP) agreement, FTP (File Transfer Protocol, FTP) agreement etc. usually; Other user can directly obtain the multimedia file that needs from server; But the mode of sharing of this multimedia file need be accomplished whole file storage by server, has increased the pressure of the network bandwidth; And above-mentioned file need can offer the user who needs through twice transmission; Promptly upload onto the server, be downloaded to multimedia file party in request from server again, increased the complexity of file transfer thus from the multimedia file provider; Can also pass through the mutual multimedia file of Email attachment in the prior art; But annex can only transmit the file of tens sizes usually; Promptly only can transmit the less pictorial information of size, then can't transmit, therefore greatly limit the mutual diversity of multimedia file for larger-size video information; In addition, if multimedia file provider and party in request login IM software simultaneously, also can carry out the instantaneous transmission of multimedia file, but this transmission means is to the having relatively high expectations of real-time, either party does not login then all can not carry out the transmission of multimedia file.
