Method and device for downloading data

Abstract

The invention discloses a method and device for downloading data, belonging to the technical field of downloading. The method comprises the following steps: receiving a download request from a user, inquiring the resource of the data to be downloaded from a resource server, and judging whether the resource is a secondary resource of each part of the split data to be downloaded; if yes, staring to download each part of the split data to be downloaded, merging the downloaded parts so as to obtain the data to be downloaded; and if no, downloading the data to be downloaded from the resource. The device comprises a receiving module, an inquiring module and a downloading module. In the invention, an anti-theft chain effect is achieved by virtue of split downloading, and the downloading parallelization level is high, thereby improving the downloading speed, saving the downloading time, meeting the requirement of a user on a high downloading speed and maximally saving the bandwidth cost of the server. When the method and device provided by the invention are applied to a peer-to-peer (P2P) downloading mode, the contribution rate of the P2P can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of downloading, in particular to a method and device for downloading data. Background technique [0002] Data downloading is one of the main applications of the Internet, and it is also the application that occupies the most server bandwidth. At present, data download usually adopts the C / S (Client / Server, client / server) mode. The client sends a request to the resource server through the browser, and the resource server returns the data corresponding to the request to the client to complete the download. This mode It can fully meet the download demand of small data volume. With the increasing development of the network and the diversification of user needs, the application of large data volume has become more common, such as the download of multimedia files, including video files, audio files, etc., as well as the download of games and other application software, etc. . The download of these large amounts...

Problems solved by technology

Regardless of the download method, the existing download tools have the following disadvantages: it will cause serious hotlinking problems. For resource providers, anti-hotlinking technology must be used to ensure that resources are obtained in a licensed manner, otherwise, the resources can be Obtained by any user in any way, which will bring huge losses to the resource provider

In addition, when downloading a large file, because the file is too large, it is not conducive to the dissemination of information, and it is quite time-consuming, especially when the download fails and needs to be downloaded again, this is undoubtedly an unacceptable thing for users
