Embodiment Construction

[0023] The embodiment of the present invention finds the device (including client and server) that stores the file through the content data of the file or the content signature related to the content data, so that the client that downloads the file can download the file from all devices that store the file. Files are not limited by the identification of similar torrent files, and more data sources can be obtained, and when the device storing the file and the client downloading the file are in the same LAN, it does not need to occupy the egress bandwidth of the LAN, which alleviates the problem of network congestion Condition.

[0024] The files in the embodiment of the present invention include text, picture, audio and video files, and their combined forms, such as web pages including text and pictures, movies including audio and video, and the like. Since the present embodiment is to improve the download speed, the application effect is better on relatively large files, such ...

Abstract

The present invention discloses a method of data download, which is used to improve download speed. The method is: downloading partial content data or content signature of a file, wherein the content signature is obtained by processing the content data of the file according to the predetermined algorithm and the content signature uniquely identified the unprocessed content data; determine whether any equipment with the file is available in the network, according to the partial content data or content signature; and continue downloading the file from the equipment, when determine the equipment with the file is available. The present invention also discloses a device.

Description

technical field [0001] The invention relates to the fields of computer and communication, in particular to a method and device for downloading data. Background technique [0002] One of the main applications of the Internet is resource sharing, and users can obtain the information and data they need through the Internet. At present, there are two main download methods in the prior art, one is unicast download, its files are only stored in the server, each file has a file identifier, and the client sends data to the server for download according to the server's network address and file identifier request, the server sends data to the client after responding to the request, and the client receives the data and completes the download. For its network structure, see figure 1 shown. In this way, a large number of clients download data from the server at the same time, which will occupy a large amount of system resources, and the burden on the server is heavy. If multiple server...
