The full name of CDN is Content Delivery Network. The basic idea is to avoid the bottlenecks and links on the Internet that may affect the speed and stability of data transmission as much as possible, so as to make the content transmission faster and more stable.

To put it simply, the data on the original server is copied to other servers, and when the user accesses, the data on that server is almost accessed by that server. CDN acceleration has the advantage of low cost and fast speed. It is suitable for a large number of visits**.

CDN stands for Content Delivery Network, and the Chinese name is Content Delivery Network. It can act as an acceleration for **. According to my personal understanding, if a ** server is deployed in the Northeast region, Harbin City, Heilongjiang.

But its customers are from South China. One south and one north, the distance is too far. In addition, the bandwidth resources are limited, and there may be lag or slow speed during access.

In this case, you can consider using a CDN solution.

Operators have a large number of CDN servers (called cache servers from a professional point of view) deployed in various regions of the country, and each server has sufficient bandwidth resources. As long as the service is enabled, the CDN server will prefetch the data from the specified customer** and cache it on the CDN server. When a user accesses, it will be directed to the CDN server in the user's nearest region through domain name resolution, and the user does not need to connect to the original server (called the origin server from a professional point of view), but only needs to connect to the server in the nearby computer room to access.

There will be a speed increase.

My level is limited, if there are errors or deficiencies, please point out the criticism!

CDN acceleration simply put, it copies the data on the original server to another server, and when the user accesses it, the data on that server is the closest to that server. CDN acceleration has the advantage of low cost and fast speed. It is suitable for a large number of visits**.

CDN accelerates the understanding, and a more reasonable answer has been given upstairs. CDN acceleration is generally used to solve several problems. 1. User marginal issues; 2. Reasonable diversion of user traffic; 3. Improve the experience of user visits.

CDN: Content Distribution License; The full name of the business is: "Class I Value-added Telecommunications Business License - CDN Business License".

Meaning: It refers to the use of node server clusters distributed in different regions to form a traffic distribution management platform to provide users with decentralized storage and caching services. According to the business scope, CDN content distribution licenses are divided into the whole network and the ground network.

The whole network license shall be handled by the Ministry of Industry and Information Technology of the People's Republic of China, and the ground network license shall be handled by the Provincial Communications Administration.

In the course of work, the following businesses need to apply for CDN content distribution licenses:

To apply for a CDN content distribution license, the following conditions are required:

01The operator is a company established in accordance with the law.

02The registered capital of the company is more than 1000W.

03 Have the necessary site and the technical solution that can be implemented.

04There is a certificate of a person who is suitable for the activities to be carried out.

05The company has the credibility and ability to provide long-term services especially for enterprises.

06 The enterprise has no information related to the punishment of telecommunications violations within three years.

07Other conditions stipulated by the state.

7. Provide operator cooperation agreement.

After turning on CDN, users in different regions will access different servers, and the real server (source server) is generally only CDN nodes go back to access and obtain, and users across the country access the rabbit CDN node server, and do not directly access the source server, so that you can introduce the broadband resources of the server and reduce the pressure on the server.

CDN is a technology that improves the speed at which users can access web pages, and the full name is Content Delivery Network. The biggest impact on the technology is to make it faster, and this technology was originally invented to solve the problem of network congestion that may occur in the future.

CDN acceleration can be simply understood as network distribution, which disperses traffic to access concurrent or non-concurrent requests and reduces requests from the origin server. To put it simply, it can be understood in this way, if there is no CDN, the user accesses, it will directly request your source server space, at this time you are a source IP response to n user requests, if the traffic is large, affected by bandwidth and other reasons, you will become very stuck, if the CDN is applied, it is equivalent to copying your **content distribution to the node server, such as 30 nodes of CDN, then the user accesses at this time, and will get the response of the node server in the principle of proximityOf course, combined with the cdn caching strategy, some of the data that is not there will be returned to the source request, at this time, the access speed is greatly improved, and only 30% of the response needs to be fed back by your origin server, the response pressure is greatly reduced, and the stability is better.

CDN cloud acceleration fee standard is as follows:

1. Traffic fees

CDN cloud acceleration service providers generally charge fees based on the user's traffic consumption, that is, the user's data transmission volume. Generally speaking, traffic fees are billed based on the user's usage and usage, and the fee is generally around a few GB.

2. Bandwidth fees

CDN cloud acceleration service providers generally charge fees based on the bandwidth used by users, that is, the bandwidth used by users. Generally speaking, bandwidth fees are billed based on the user's usage and usage, and the cost is generally about a few Mbps per month.

3. Service fees

CDN cloud acceleration service providers generally charge a certain amount of service fees based on the type of service you use, such as access control, security protection, and data backup.

4. Configuration fees

CDN cloud acceleration service providers generally charge a certain configuration fee based on user needs and specific configurations, such as the number of nodes, cache space, and advanced functions.

What is CDN Acceleration?

With the rapid development of the Internet, more and more applications need to carry out a large amount of data transmission, such as **, **, audio, etc. However, for some users across regions and networks, access speed is often affected by network latency, network bottlenecks, and other factors, resulting in slow user access** or applications that are too slow or error-incorrect. This is where CDN acceleration becomes an effective solution.

How Does CDN Acceleration Work?

CDN stands for Content Delivery Network, which is a network architecture based on cloud computing and distributed network technology for efficient transmission. Generally speaking, a CDN network deploys a series of cache servers around the world, which cache and distribute the content of ** or applications to the network nodes where users are located to achieve high-speed transmission.

Specifically, when a user accesses a user or an application, their request is first routed to the nearest CDN node to the user, which determines which cache server to fetch content from based on a series of parameters such as the user's location. If the node has already cached the requested content, it is transmitted directly to the user; Otherwise, the node initiates a request to the other CDN nodes and passes the response back to the user. In this way, the user's access speed can be improved to a certain extent.

What Are the Benefits of CDN Acceleration?

CDN acceleration has the following advantages:

Improve access speed: Since the CDN node is closer to the user and the transmission distance is shorter, the user's access speed can be greatly accelerated.

Reduced server load: The CDN cache server can return the requested content directly to the user, thereby reducing the load pressure on the origin server.

Improve global accessibility: The distributed architecture of the CDN network can effectively reduce network latency and improve the access quality of users around the world.

Summary. CDN acceleration is an effective network optimization solution that can improve user access speed, reduce server load, and improve global accessibility. In the current Internet era, CDN acceleration has become a must-have technology for more and more applications.

What is CDN Acceleration?

With the rapid development of the Internet, the traffic of many enterprises is getting bigger and bigger, and the user experience is also being paid more and more attention. In this case, CDN (Content Delivery Network) acceleration comes into being.

CDN acceleration.

The core principle of CDN acceleration is "nearby access", that is, when a user requests a resource, the CDN will cache the resource on the node closest to the user, so as to improve the access speed. When a user requests a resource, the CDN automatically retrieves the resource from the node closest to the user based on the user's physical location.

For example, if a user accesses a ** in Beijing, the CDN caches the resources of that ** on the node in Beijing. In this way, when a user requests a resource, it can be loaded directly from the node in Beijing, instead of getting it from the server, thus improving the access speed.

Advantages of CDN acceleration.

CDN acceleration has many advantages, which are mainly reflected in the following aspects:

Reduced load: CDNs can spread traffic across nodes for processing, reducing the load on the server and improving reliability and resilience to extreme situations.

Application scenarios for CDN acceleration.

CDN acceleration can be used in a wide range of scenarios, mainly in the following aspects:

Game acceleration: CDN can provide a faster and more stable network environment for games, improving the smoothness and stability of games.

CDN accelerates the future of development.

With the continuous development of Internet technology, CDN acceleration is also constantly evolving. In the future, CDN acceleration will be continuously improved and developed in the following aspects:

Intelligent routing: CDN will not only select the best node based on geographical location, but also intelligently select nodes based on multiple factors such as network conditions and bandwidth conditions to improve access speed.

Protocol upgrade: As the HTTP 3 protocol continues to mature, CDN will be gradually upgraded to HTTP 3 to further improve the acceleration effect.

In short, CDN acceleration is a very important acceleration technology, which is widely used in the fields of **, **, games, etc. In the future, with the continuous development of technology, CDN acceleration will be more widely used and evolve.

CDN is a strategically deployed overall system that can help users solve problems such as distributed storage, load balancing, redirection of network requests, and content management.
