Compared with other CDN service providers, the main advantages of CDN include stable and fast, cost-effective, easy to use, efficient and intelligent. More users will ask about the advantage of stability and speed. Generally speaking, CDN is characterized by sharing the pressure on the origin server, avoiding network congestion, accelerating the distribution of website content in different regions and different scenarios, and improving the speed of resource access. Here is an introduction to the principle of CDN acceleration service:

How does cdn achieve acceleration? CDN is different from mirroring because it is smarter than mirroring. It can be used as an analogy: CDN= smarter mirroring + caching + traffic diversion. Therefore, CDN can obviously improve the efficiency of information flow in Internet network.

Technically, it comprehensively solves the problems of small network bandwidth, large number of user visits and uneven distribution of sites, so as to improve the response speed of users visiting the website.

The implementation of CDN can be divided into three categories: mirror, cache and direct connect.

Mirror sites are the most common, allowing content to be published directly, suitable for static and quasi-dynamic data synchronization. However, the cost of purchasing and maintaining the new server is high, and mirror servers must be set up in each region, equipped with professional and technical personnel for management and maintenance. For large websites, the cost of updating bandwidth has also been greatly increased.

Caching, with low cost, is suitable for static content. Internet statistics show that more than 80% of users often visit 20% of the site's content. under this rule, the cache server can handle most customers' static requests, while the original server only needs to handle about 20% of non-cache requests and dynamic requests, which greatly speeds up the response time of customer requests and reduces the load on the original server.

CDN services typically place cache servers on key nodes across the country. The dedicated line allows users to access the data source directly, which can realize the dynamic synchronization of the data. The above is an introduction to how cdn achieves acceleration.
