What does cdn acceleration service mean? In short, CDN service providers deploy node servers all over the country, and if you want to use their CDN, they will cache all the cached content in your site to node servers everywhere. In this way, visitors from different regions and different operators can visit your website on the nearest node without going to your origin server. So as to have the internal effect of acceleration.

I. the characteristics of CDN

1. High speed

Using the BGP line as the CDN node ensures the speed problem when the CDN reads the original data.

2. Band 5261 wide cost is greatly reduced.

Because 70% of telecom customers access speed itself is very fast, do not need to accelerate, this part of the traffic is completely saved. Accelerate only for about 25% of Netcom customers.

3. Safety 4102 good sex

The original server of user 1653 and CDN accelerates the encrypted compression transmission between each node, and the website in the node server exists in the form of file. Even if the node server is hacked, the hacker cannot get any valuable data back.

4. High reliability

In the CDN acceleration system, any node server network outage, attack paralysis or system crash does not hinder the operation of the whole network and the access of the vast majority of users. The system can automatically judge and guide the user to the fastest answering node among the remaining nodes.

5. Easy deployment

You only need to modify the domain name resolution record to the specified alias, and no other action is required.

Second, how to check whether the website is accelerated by cdn

To see whether a website opens CDN, the method is very simple, as long as you ping a URL in different regions. For example, the IP address you get in Beijing ping is one, but the IP you get in Zhejiang ping the same URL is another. If you ping the same URL in different regions and get different IP addresses like this, then you can judge that the site has opened CDN acceleration.

If the website does not have CDN enabled, the Ping URL in different regions is the real address of the website server. If CDN acceleration is enabled, the content of the website will be cached to the nearest server in each region, so accessing IP will change. According to this principle, it is easy to judge whether the website has CDN enabled.

About what cdn acceleration service means to share here, I hope that the above content can have a certain reference value for you, you can learn to apply. If you like this article, you might as well share it for more people to see.
