After purchasing the CDN service, users will be more concerned about the actual effect in the process of using it. First of all, make sure that it has been activated successfully, and then follow the basic steps to add accelerated domain names and configure CNAME. After all, you can test whether the CDN acceleration is successful. Today, I would like to introduce to you what is the acceleration principle of cdn video.

What is the principle of cdn video acceleration? Video is one of the most bandwidth-consuming forms of transmission in the Internet. Video websites have a very high demand for cloud server bandwidth, which does not use CDN acceleration, which affects the visit volume, download and transmission of the website. Video CDN acceleration can be used to offload the video server.

The construction process of video CDN  

Building video CDN is generally composed of two servers: cache server and content distribution server. Cache servers (CDN nodes) are distributed all over the world and store relevant video content through policies, while content distribution servers distribute video content from video servers to each cache server according to a certain policy.

To take a simple example: when a video website needs to publish a new video, the video server will first send the video content to the content distributor of CDN, and then the content distributor will send the video content to the cache servers around CDN according to the set policy.

When the user clicks on the video of the video website, the video website will cooperate with the CDN network to find the best cache server for the user according to the user's geographical location (where) and the network situation (Telecom, Unicom).

Of course, the use of video CDN can not only reduce the bandwidth demand of the video server, but also effectively solve the problem of interconnection between telecom and China Unicom, hide the real IP address and protect the video server from attack. The mission of the whole video CDN is to give users a better service experience with lower unit service cost.

The above is an introduction to cdn video acceleration.
