BT download method, device and system

Abstract

The embodiment of the invention discloses a BT download method, which comprises the following steps: obtaining a first request data packet which is sent to an index server in a network; sending a second request data packet to the index server according to resource information to be downloaded which is obtained by analyzing the first request data packet, wherein the second request data packet is used for requesting for owning client-end list information of resources to be downloaded from the index server; receiving the client-end list information returned by the index server; interacting with at least one client end in the client-end list and obtaining fragment information of the resources to be downloaded, which comprises fragment size information; and downloading the resources to be downloaded from at least one client end according to the fragment information of the resources to be downloaded. By adopting the download method, BT resources can be downloaded when seed documents cannot be found, thus improving the reliability of BT resource downloading.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a BT download method, device and system. Background technique [0002] Peer-to-peer technology (P2P for short), also known as peer-to-peer Internet technology, is a network information exchange method relative to the client / server (C / S) model. In a P2P network, each node can serve as a client to get services from other nodes, or serve as a server to provide services to other nodes. Since the P2P network can greatly alleviate the problems of excessive pressure on the server side and the single point of failure in the traditional C / S network architecture, and can make full use of the abundant resources of the terminal, the P2P technology is widely used in various application fields of computer networks. , such as distributed scientific computing, file sharing, live streaming and on-demand, voice communication, and online game support platforms. [0003] BT is the abbreviat...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that in the existing BT download process, the client must first search the network to obtain the seed file of the resource to be downloaded, and then BT resources can only be downloaded from other peer nodes based on the torrent file. However, due to frequent changes in websites with BT torrent files and other reasons, it is difficult to obtain some BT torrent files. Therefore, there are a large number of BT resources that cannot be downloaded because the torrent file cannot be found. Condition
