Problems solved by technology

[0005] If the user only wants to obtain part of the content of a data resource, such as watching the last 5 minutes of a certain video, the cache server will only obtain the corresponding part of the data resource from the resource server, and if another user wants to obtain the same For all data resources or other undownloaded content, the cache server needs to establish a connection with the resource server again, and re-download the data resource from the resource server. In this way, it is easy to cause resource storage redundancy in the cache server, and data resources The acquisition efficiency is low

Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0056]An embodiment of the present invention provides a method for downloading data. The execution body of the method may be a cache server, wherein the cache server may be a server used to store data resources in a CDN service cluster. In the entire network scene, the same geographical area Multiple cache servers can be deployed inside, and each cache server is used to store different data resources, and multiple cache servers can be connected to the distributor in the CDN service cluster. The distributor can be used to receive the resource acquisition request sent by the user terminal, and distribute the resource acquisition request to the corresponding cache server according to the resource uniqueness policy, so that the requests for...

Abstract

The present invention discloses a method and an apparatus for downloading data, and belongs to the technical field of data storage. The method comprises that: a cache server determines at least one locally stored to-be-added incomplete resource; when the preset download trigger condition is met, the cache server automatically downloads and stores the remaining data of the at least one incomplete resource; and when detecting a predetermined stop download event, the cache server stops downloading the remaining data. According to the method and apparatus disclosed by the present invention, the data resource acquisition efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a method and device for downloading data. Background technique [0002] With the continuous advancement of Internet technology, CDN (Content Delivery Network, Content Delivery Network) services are also developing rapidly. The CDN service cluster includes a large number of cache servers for storing data resources, and users can obtain the data resources stored in them in a short time. [0003] When a user wants to obtain a data resource through the terminal, such as watching a video or downloading a file, the user can send a resource acquisition request through the terminal. After the CDN service cluster receives a resource acquisition request, it can distribute it to a cache server. If the above data resource is not stored in the cache server, it can obtain the data resource from the corresponding resource server, and then the data Resources are fed back to the terminal, ...
