What is cdn Acceleration Service?

CDN is the abbreviation of Content Delivery Network, which means "Content Distribution Network". Generally speaking, what we call CDN acceleration generally refers to the acceleration of websites or the acceleration of users downloading resources.

Cdn acceleration is to solve the problem of access delay caused by distribution, bandwidth and server performance, and is suitable for site acceleration, on-demand and live broadcast. Thus, users can get the required content nearby, solve the congestion of Internet network, and improve the response speed and success rate of users visiting websites.

Cdn is a strategically deployed overall system, including four elements: distributed storage, load balancing, network request redirection and content management. Content management and global network traffic management are the core of CDN. Cdn ensures that the content provides services for users' requests in an extremely efficient way by judging user proximity and server load.

Main features of cdn acceleration:

1, the local cache is accelerated, which improves the access speed of enterprise websites (especially those containing a large number of pictures and static pages) and greatly improves the stability of the above websites.

2. Mirror service eliminates the influence of interconnection bottleneck between different operators, realizes network acceleration across operators, and ensures that users of different networks can obtain good access quality.

3. Remote acceleration: Remote access users intelligently and automatically select the cache server according to DNS load balancing technology, and select the fastest cache server to accelerate remote access.

4. Bandwidth optimization, which can automatically generate a remote mirror cache server of the server and read data from the cache server when a remote user visits, thereby reducing the bandwidth of remote access, sharing network traffic and reducing the load of the original WEB server.

5. Cluster anti-attack, widely distributed CDN nodes and intelligent redundancy mechanism between nodes can effectively prevent hackers from invading, reduce the impact of various DDoS attacks on websites, and ensure better service quality.
