CDN (Content Delivery Network)-based content management system

Abstract

The invention provides a CDN (Content Delivery Network)-based content management system. The CDN content management system comprises a distributed type scheduling center, a large data center, a task execution server cluster, a distributed reliability coordination system and a content caching server; the distributed scheduling center is used for carrying out task scheduling according to a client request; the large data center is used for storing client task request data; the task execution server cluster is used for receiving a task conversion instruction sent by a distributed scheduling server and sending a task instruction to a corresponding region and the content caching server of an operator; the distributed reliability scheduling system is used for storing states and attributes of all servers of the content management system; the content caching server is used for caching files of a client. The CDN-based content management system can be used for realizing effective management of cache files.

Description

technical field [0001] The present invention relates to a content management system, in particular to a content management system based on a CDN (Content Delivery Network, content distribution network). Background technique [0002] With the vigorous development of the Internet, more and more users browse the web, listen to music, and watch videos through the Internet. In order to ensure that users can quickly obtain network information, more and more Internet websites need to be accelerated through CDN. The basic idea of ​​CDN 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. Specifically, the CDN improves the access speed of the client browser by using edge nodes to cache customer data. [0003] In the prior art, the edge cache server caches files in the following two situations: [0004] 1. The customer sends a push request, in or...

[0006] However, the above method causes the edge server to cache a large number of cache files of the client, which has the following disadvantages:

[0007] (1) Existing CDN products lack content management for edge servers, and cannot manage the entire lifecycle of cached files;

[0008] (2) It is not possible to perform targeted processing of cached files according to different cache types, such as live streaming control, streaming media format conversion, image format conversion, etc. for streaming media content;

[0009] (3) The prefetch function for cached files cannot achieve accurate range control, fine flow control, and hot and cold prefetch
