Abstract

The invention discloses a method for downloading streaming media resources and a caching server, wherein the method includes: receiving a resource acquisition request directed to a target streaming media resource; The server sends a data download request for obtaining a specified data segment in the target streaming media resource; the specified data segment is at least used to represent the playback duration of the target streaming media resource; receiving the feedback from the source station server includes the Specify a response message for the data segment, and calculate a return-to-source rate adapted to the target streaming media resource according to the response message; download the target streaming media resource from the source station server according to the return-to-source rate , and when downloading the target streaming media resource, feed back the downloaded content to the originator of the resource acquisition request. The technical solution provided by this application can reduce the back-to-source bandwidth in the CDN, thereby saving the operating cost of the CDN.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method for downloading streaming media resources and a cache server. Background technique [0002] In a CDN (Content Delivery Network, content distribution network), generally, a cache server and an origin server may be included, wherein the cache server may be deployed in different geographic locations according to geographic location planning. When a user's client accesses network resources through the CDN, the access request can first be distributed to a cache server through a load balancing strategy. Then the cache server can provide the corresponding network resource in the local cache to the client, or download the corresponding network resource from the origin server and provide it to the client. [0003] At present, in order to provide users with network resources as soon as possible, the cache server in the CDN usually downloads network resources from the source ...
