High-availability CDN service mechanism based on multiple clouds

Abstract

The invention discloses a high-availability CDN service mechanism based on multiple clouds. The mechanism comprises a multi-cloud CDN configuration module, a CDN fault detection module and a line switching module. The CDN configuration module constructs CDN configuration service based on a multi-cloud CDN. The CDN access of a main producer is provided; the configuration of at least one standby producer can be defaulted to be redundant; the CDN fault detection module deploys CDN monitoring nodes in all regions of the country, real-time response duration information of each domain name acceleration node is collected; the collected information is synchronized to the configuration center through the message queue, CDN service fault real-time monitoring and minute-level fault quick recovery canbe achieved, so that high availability of CDN service is achieved, huge pressure brought to a source station due to the fact that a large amount of back-to-source flow occurs due to CDN faults is avoided, and customer service stability is guaranteed.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a multi-cloud-based highly available CDN service mechanism. Background technique [0002] With the rapid development of the cloud computing era, especially the advent of the streaming media big video era, users who only rely on CDN services provided by a single service provider will face the following problems: [0003] 1) The effective time of a single service provider's service is uncertain, and the fault tolerance rate is low, so it is impossible to truly achieve high availability. [0004] 2) Different service providers have large differences in CDN node density in different regions, and relying on a single service provider cannot achieve optimal cost performance. [0005] 3) CDN manufacturers continue to use technology and resources to break through the above limitations, but due to competition, the resources of a single service provider are relatively closed. [0006] To...
