Content distribution network (Content Delivery Network, referred to as CDN) is a distributed network, which is established and covered on the bearer network, which is composed of edge nodes and cloud servers distributed in different areas. CDN shares the pressure on the origin server, avoids network congestion, ensures that the distribution of website content is accelerated in different regions and different scenarios, and improves the speed of resource access. Today, I will tell you how to speed up cdn.

How does cdn speed up? The design 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 cloud servers everywhere in the network to form a layer of intelligent virtual network based on the existing Internet, the CDN system can real-time monitor the network traffic and the connection of each node, load status, distance to users and response time and other comprehensive information to the user's request.

An example of cdn acceleration shows:

Under the premise of a certain Internet speed, CDN is like a courier in the network, and CDN is a very smart courier. TA is not running around with brute force, TA has also built a lot of delivery points, the nearest express (cache); TA is good at optimizing delivery routes (scheduling); and will repackage packages more reasonably (protocol optimization).

Domestic websites, live streaming and video platforms with high visit volume all use CDN network acceleration technology. Although the visit of the website is huge, it will feel very fast no matter where it is visited. In general, if the server is in Netcom, the access of telecom users is very slow, and if the server is in telecom, the access of Netcom users is very slow.

By adding a new network architecture to the existing Internet, publishing the content of the website to the cache server closest to the user, and through the technology of DNS load balancing, we can judge the user source to visit the cache server nearby to get the required content, solve the Internet network congestion, and improve the response speed of users visiting the website, just like providing multiple accelerators distributed in different places. In order to achieve the goal of fast and redundant acceleration for multiple websites.

The above is about how to accelerate cdn. The website's virtual host can enjoy Baidu's massive CDN node resources for free, rich node resources, global coverage, and unlimited traffic to provide acceleration services for a large number of users.
