Content distribution network (Content Delivery Network, referred to as CDN) is a distributed network, which is established and covered on the bearer network, and is composed of server groups of edge nodes distributed in different areas. CDN shares the pressure on the origin server, avoids network congestion, ensures that the distribution of website content is accelerated in different regions and different scenarios, and improves the speed of resource access. Today, I will introduce to you the basic concepts and main advantages of high defense CDN.

What is High Defense cdn? High-defense cdn is achieved through high-defense DNS, the purpose is to better service network. High-defense cdn determines the source through the intelligent system, and then gives feedback to the user, which can reduce the complexity of the user's use process. Through intelligent DNS parsing, website visitors can connect to the response server to prevent a server from being paralyzed by too many visitors.

The advantages of high defense cdn are as follows:

1. Automation. Guided self-help, embedded information improvement, error and conflict reminders. Rich configuration items, testing the availability of station sources, customizing disaster preparedness, controlling access rules, and customizing cache policies.

two。 Multi-service support. The cache of static content is accelerated to eliminate the calm of interconnection, and large-scale concurrent traffic can be handled calmly. Dynamic content through intelligent routing, private protocol transfer, content compression and other means to provide efficient and stable link, improve link transmission efficiency, ensure that dynamic content transmission is fast and accurate, support web pages, downloads, VOD and other types of services.

3. Security protection. Hide the origin server IP to prevent hackers from obtaining the real origin server IP. Intelligent protection, protect the website from ddos attacks, and improve the security of the website on the premise of accelerating performance.

4. Weak network acceleration, through the underlying protocol optimization, effectively combat the fluctuations of various network nodes in the process of data transmission, and solve common problems such as download failures, download errors, slow speed, etc., in the case of slow download speed, the data transmission speed can be increased by 10 times, playing the role of CDN website acceleration. High-defense CDN only improves the performance of CDN and pays more attention to network security.

The above is the explanation for what is high defense cdn.
