Today, I would like to talk to you about what is called CDN, many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

What is CDN?

CDN is an intelligent virtual network based on the existing network. Relying on the edge servers deployed everywhere, through the load balancing, content distribution, scheduling and other functional modules of the central platform, users can get the content they need nearby, reduce network congestion, and improve the response speed and hit rate of user access.

Basic principles of CDN

The basic principle of CDN is that all kinds of cache servers are widely used, and these cache servers are distributed to the areas or networks where users are relatively concentrated. When users visit the website, the global load technology is used to direct the user's access to the nearest working cache server, and the cache server directly responds to the user's request.

The basic idea of CDN is to avoid the bottlenecks and links that may affect the speed and stability of data transmission on the Internet as far as possible, so as to make the content transmission faster and more stable. By placing node servers everywhere in the network to form a layer of intelligent virtual network based on the existing Internet, the CDN system can redirect the user's request to the nearest service node in real time according to the comprehensive information such as network traffic, connection of each node, load status, distance to the user and response time. Its purpose is to enable users to get the content they need nearby, solve the situation of Internet network congestion, and improve the response speed of users visiting the website.
