After purchasing the CDN service, users will be more concerned about the actual effect in the process of using it. First of all, you need to make sure that it has been activated successfully, and then follow the basic steps to add accelerated domain names and configure CNAME. After all these have been successfully completed, CDN can be used normally. Many users have a question, which is often asked, that is, how to know that your cdn is better than that of other service providers.

What conditions should a better cdn have? Cdn technology distributes the content of the origin server to the nodes closest to users all over the world, shortens the physical distance from the user to the node, enables users to get the content they need nearby, reduces the delay, improves the response speed and availability of the website, and solves the problems such as distribution, bandwidth, server performance burst, source server pressure, route hopping and so on. A good cdn should have the following characteristics.

Stable architecture

Meet the needs of users' private customized CDN. Monitoring real-time network traffic and node load quickly directs users to the nearest optimal cache node, so that users can get the content they need as close as possible, thus greatly speeding up the corresponding speed for users to visit the website.

Precise scheduling

Deploy the load balancing system node server cluster, build a layer of intelligent virtual network based on the existing Internet technology, effectively protect the source server address and greatly reduce the single point of failure by distributing the content to different network nodes.

Protect and hide the real IP

Through the turning point of several nodes in the CDN server, we can hide the real IP and reduce the chance of the web page being attacked by direct ddos.

Efficient network

Global node deployment to establish a wide range of coverage and stable performance of the network system. By optimizing the routing between users to the website, improving the congestion of the internet network, compressing the transmission content, reducing the data transmission, improving the TCP transmission algorithm, improving the network transmission speed of the dynamic content of the website, so as to achieve the purpose of dynamic content acceleration.

Cache acceleration Settin

CDN server memory web static data (such as pictures, videos, text, etc.), end-users connect to it, reduce the time to read data to the website, and speed up the browsing experience.

The above is about a better introduction to cdn.
