Problems solved by technology

[0003] However, since each existing CDN node will cache all the files in the data source as much as possible, it will bring a large storage cost
Moreover, the content of some files has not changed, only the download address. If the URL of the file has changed, according to the existing CDN caching method, multiple files with the same content and different URLs will be cached in one node, that is, duplicate Data caching, which further leads to higher storage costs

Abstract

The present invention discloses a download management device, method and data download system, wherein the download management device includes: a buffer configured to cache each file obtained from a data source node and the content abstract of each file, the content of the file The abstract is the data generated by specific data conversion on the content of the file; the parser is configured to obtain the file download request from the client device, and parse out the content abstract of the requested file according to the download address of the file download request; the finder, configured to look in the cache based on the content summary of the file, and if found, transmit the requested file to the client device; The data source node obtains the requested file, transmits it to the client device, and provides the requested file to the cache for caching.

Description

technical field [0001] The present invention relates to the technical field of data download, in particular to a download management device used in edge nodes, a data download system, and a download management method used in the data download system. Background technique [0002] The existing CDN (Content Delivery Network, content distribution network) distributes data to each edge node and shortens the distance with the client to improve the data access speed. The basic idea is to avoid bottlenecks and links on the Internet that may affect the speed and stability of data transmission as much as possible, so as to make content transmission faster and more stable. The CDN system can redirect the user's request to the service node closest to the user in real time according to comprehensive information such as network traffic, connection of each node, load status, distance to the user, and response time. [0003] However, since each existing CDN node caches all the files in th...
