Compared with other CDN service providers, the main advantages of CDN include stable and fast, cost-effective, easy to use, efficient and intelligent. More users will ask about the advantage of stability and speed. Generally speaking, CDN is characterized by sharing the pressure on the origin server, avoiding network congestion, accelerating the distribution of website content in different regions and different scenarios, and improving the speed of resource access. Here is an introduction to the principle of CDN acceleration service:

What is the principle of cdn acceleration? The principle of CDN acceleration is that the content of the website is cached at the edge of the network (the place closest to the user's access to the network), and then when the user visits the content of the website, the user's request is routed or directed to the cache server that is closest to the user's access to the network or has the best access effect through the scheduling system, and the cache server provides the content service for the user. Compared with directly accessing the origin server, this method shortens the network distance between users and content, thus achieving the effect of acceleration.

With the development of the Internet, users pay more and more attention to the browsing speed and effect of the website when using the Internet, but due to the surge in the number of Internet users and the long network access path, the access quality of users is seriously affected. Especially when the link between the user and the website is suddenly congested with large traffic data, the poor quality of access is an urgent problem to be solved in the areas with the rapid increase of Internet users in different places. How to enable users everywhere to conduct high-quality access, and minimize the resulting costs and website management pressure? The content distribution network (Content Delivery Network,CDN) was born.

The basic principle of cdn network acceleration: by placing node servers everywhere in the network, a new intelligent virtual network is built on the basis of the existing Internet, which can redirect the user's request to the nearest service node according to the comprehensive information such as the network traffic and the connection of each node, load status, distance to the user and response time.

The principle of cdn acceleration is the same as the principle of mobile phone base stations that we encounter in our daily life. Every place has a signal tower, which ensures the signal strength of every place, and the principle of cdn network acceleration is the same!
