Shangpin China tells you what benefits can CDN bring to the website? one

1、 First, we need to know what is CDN? What are the functions and functions of CDN?

The full name of CDN is "Content Delivery Network", that is, the content distribution network. CDN is an intelligent virtual network built on the basis of the existing network. Relying on edge servers deployed in various places and through the load balancing, content distribution, scheduling and other functions of the central platform, the key technologies of CDN mainly include content storage and distribution technologies.

CDN enables users to obtain the required content nearby, reduce network congestion, and improve user access response speed and hit rate.

2、 What are the components of CDN?

The CDN includes functional entities, including content caching devices, content switches, content routers, CDN content management systems, etc.

(1) The content cache is a CDN network node located at the user access point. It is a content providing device for end users and can cache Static web page Content and media content.

(2) The content switch is located at the user access concentration point, which can balance the load of multiple content cache devices at a single point, and perform cache load balancing and access control on the content.

3、 So what are the benefits of CDN?

1. Can reduce bandwidth cost

CDN can be used to realize the nationwide website laying, without the investment in new broadband costs and image synchronization of multiple servers, so as to minimize the cost of bandwidth and human maintenance.

2. It can improve user access speed

If the site contains a large number of pictures and static pages, the access speed will be slower. CDN can cover almost all domestic lines, help users automatically match the fastest access speed, and effectively improve the user's access speed and browsing experience.

The average download speed of national access before CDN is started is about 590KB/s.

After CDN is enabled, the average transmission speed of nationwide access is about 5.76MB/s.

3. It can reduce the pressure of the origin station

For sudden traffic on the website, no user intervention is required, and automatic response and adjustment are made to effectively reduce the pressure on the origin site.

4. Cluster can resist attacks

The widely distributed CDN nodes hide the real IP address of the source station and the CDN's natural anti attack capability, which can effectively prevent hacker intrusion and reduce the impact of various DDOS and CC attacks on the website, while ensuring that the security of the source station will be greatly improved.
