[0005] However, since the have message for exchanging file data block information in the BitTorrent system is local, not system-wide, the fewer data blocks calculated by the peer may be more in the entire system, and the more data calculated by the peer There may be fewer blocks in the entire system, so that the files shared by the torrent cannot be distributed to the system as quickly as possible, so that when the online time of the torrent is short, it cannot be guaranteed that the peers in the system can completely download to the torrent shared document

Embodiment 1

[0070] Corresponding to the data distribution method, the embodiment of the present invention provides a corresponding data distribution device, Figure 4 Embodiment 1 of the data distribution device provided by the present invention is described, including:

[0071] A request message receiving unit 401, configured to receive a request message requesting a data block;

[0072] A data block selection unit 402, configured to select a data block from data blocks marked as not yet sent;

[0073] A data block sending unit 403, configured to send the selected data block.

[0074] As can be seen from the above, after receiving the request message requesting the data block, this embodiment of the data distribution device selects the data block from the unsent data blocks to send, so that when the data blocks that the file is divided into have not been completely sent, each sending It is a new data block, so the shared file can be backed up in the file sharing system as quickly as po...

Abstract

The present invention relates to a network technique, in particular to a data distributing method, device and system, wherein, the data distributing method includes: receiving the request information of the request data block; selecting the data block from the data blocks which are labeled HAVE NOT BEEN SEND; and sending the selected data block. A corresponding device and a corresponding system are also provided. The technical proposal of the present invention can distribute the seed sharing documents to the document sharing system in the fastest way, thus improving the rate of success in the downloading of the documents in the document sharing system.

Description

technical field [0001] The present invention relates to data distribution technology, in particular to a data distribution method, device and system. Background technique [0002] Peer-to-peer (P2P: Peer To Peer) file sharing is currently the mainstream application in the P2P field. There are a large number of such software and they are relatively mature. With the help of such software, ordinary users distributed all over the world can easily share various files with others. However, when using this type of software to download files shared by other users, it is often found that the files cannot be downloaded completely. The data blocks of the torrent file are not backed up in the system because of the line. If there is no backup, the data blocks of some torrent files are only on the peer that shares the torrent file, but not on any other peer in the system. In the case of a backup, the data blocks of the seed file are stored on at least one other peer. When this happens, ...
