What does CDN network acceleration mean?

CDN is the content distribution network, which means acceleration. Then the website caller ID service is a website acceleration service. We can roughly understand that CDN can speed up the opening of websites.

CDN acceleration principle

How to accelerate CDN? In fact, this is the deployment of computing nodes by CDN service providers in various provinces across the country. CDN speeds up the caching of website content at the edge of the network, and then when users access the website content, the scheduling system routes or guides the user's request to the caching server nearest to the user's access network or with access effect, and the caching server provides content services for users. Compared with direct access to the source station, this method shortens the network distance between users and content, thus achieving the effect of acceleration.

What are the characteristics of CDN?

1, local acceleration, which improves the access speed of enterprise websites (especially those containing a large number of pictures and static pages) and greatly improves the stability of the above websites.

2. Mirror service eliminates the influence of interconnection bottleneck between different operators, realizes network acceleration across operators, and ensures that users of different networks can obtain good access quality.

3. Remote Accelerated Remote Access Users intelligently and automatically select the cache server according to DNS load balancing technology, and select the fastest cache server to accelerate remote access.

4. Bandwidth optimization automatically generates a remote mirror cache server of the server, which reads data from the cache server when remote users visit, thus reducing the bandwidth of remote access, sharing network traffic and reducing the load of the original WEB server.

5. CDN node cluster with widely distributed anti-attack and intelligent redundancy mechanism between nodes can effectively prevent hackers from invading, reduce the impact of various D.D.o.S attacks on websites, and ensure better service quality.
