What is the Role of CDN Acceleration

The term CDN is believed to be familiar to many friends, and we often see related reports on the Internet. Some time ago, major CDN service providers responded to the call, and CDNs have also increased speed and reduced fees. Most website operators know that CDN acceleration can speed up the opening speed of websites and the speed of users downloading resources, but there are also many new friends who are still unclear. What is CDN? What is the role of CDN acceleration?

 

CDN is the abbreviation of Content Delivery Network, which means "Content Delivery Network". The basic idea of CDN is to avoid bottlenecks and links on the Internet that may affect the speed and stability of data transmission, so that content transmission can be faster and more stable. By placing node servers in various parts of the network constituted by a layer of intelligent virtual network on the basis of the existing Internet, the CDN system can be based on the network traffic and the connection of each node, load status, distance to the user and response time in real time Such comprehensive information redirects the user's request to the service node closest to the user. So what is the role of CDN acceleration, mainly as follows:

 

1. The user browses your website at the local speed on the most optimized path; no matter how much Flash, pictures, videos...the website has, it can be accessed at high speed;

2. The quality of service required by users is improved. When the website is accessed by a large number of users, since the CDN server shares the load, the source server is stable and free from crashes;

3. Ensure that the content transmission network responds faster and safer, and meets users' high-speed access;

4. Strong scalability, the website does not need to purchase unnecessary equipment for users' burst traffic;

5. Most of the visit traffic is borne by the CDN network, which significantly reduces the operating cost of the website;

6. Improve safety and reliability, and the failure of local nodes will not affect user access. Greatly reduce the possibility of being attacked by hackers and viruses;

7. Distributed access nodes can enhance the service capabilities of the website's core applications;

8. It can be well combined with other servers to comprehensively improve website performance;

9. With powerful defense capabilities, node server defense capabilities and an overall defense system, CDN has created a three-dimensional defense system to make the website safer and more reliable.
