Problems solved by technology

[0004] At present, a large number of files in the network are stored on FTP or HTTP servers. The main reason for this situation is that the FTP protocol and the HTTP protocol have a longer history, but at this stage the Bittorrent protocol mode cannot directly support files under the FTP or HTTP protocol. download, which makes a large part of the resources in the network under the Bittorrent protocol unable to be utilized

Embodiment Construction

[0027] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, the network nodes (server node 1, common node 2 and DHT node 3) of the system for downloading files based on the BT protocol are connected through the network, and the connected network conforms to the BT protocol specification. The server node 1 is provided with a server upload module, and the main function of the server upload module is to respond to the download request of a common node in the network and transmit (upload) the requested file to the common node (specifically, the block unit of the file, that is, a file Divide into file blocks of equal size, so that these file blocks can be effectively transmitted under the condition of limited network transmission speed, and then the file blocks are merged into a file to obtain the whole file). The server node 1 may be a server that can respond to a file ...

Abstract

The invention provides a system for downloading files based on Bittorrent protocol so as to realize the aim that the resources of a server such as a FTP or HTTP server are introduced to the form of Bittorrent protocol; the system comprises a network set according to the Bittorrent protocol and network nodes used to connect the network; wherein, the network nodes comprise common nodes, DHT nodes arranged and distributed in the network and server nodes; the server nodes perform the following steps: receiving a download request from a common node and transferring a file block unit which is requested to download to the common node. A common upload module is arranged on each common node, and the common upload module is used to receive the download requests from other common nodes and sent the file block units which are requested to download to the corresponding to common nodes. Message retain modules are arranged on the DHT nodes to record the information of files which can be downloaded in the network nodes.

Description

technical field [0001] The invention relates to the technology of file transmission in the network. Background technique [0002] With the development of computer and network technology, people are getting more and more needed information files from the network. This convenient way of getting information has greatly improved the efficiency of people's life and work. The mode of obtaining information files from the network often adopts a client / server (C / S) mode, for example, downloading required information files from a website. The current information files, especially multimedia files, are getting larger and larger, which makes the efficiency of obtaining information files in the C / S mode lower and lower. Bandwidth is quickly consumed as the number of clients increases. This causes the download speed of the client to become slow, and a relatively large file needs to be downloaded for several or even dozens of hours. [0003] The current hardware technology cannot greatl...
