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 would like to introduce to you the high-defense CDN with unlimited accelerated content.

What is the high-defense cdn with unlimited accelerated content? For network traffic attacks, the website will suddenly access very slowly or inaccessible, and high-defense cdn can effectively prevent attacks such as ddos. The advantages of high defense cdn are reflected in the following aspects:

1. Node cache, intelligent object heat algorithm, hierarchical cache of HOT resources to achieve accurate acceleration of resources.

two。 High-performance cache Cache system design, balanced use of CPU multi-core processing capacity, efficient and rational use and control of memory, maximize SSD IOPS and throughput. Each node is equipped with high-speed read-write solid-state disk SSD storage, combined with SSD acceleration, greatly reduce user access waiting time and improve availability.

3. Intelligent compression can effectively reduce the size of user transmission content and accelerate the distribution effect.

4. Page optimization, remove page spaces, line breaks, TAB, comments and other redundant content, reduce the size of the page.

5. Combine multiple JavaScript/CSS files into a single request, thereby reducing the number of requests.

6. Precise scheduling, regardless of whether the site belongs to portal information, multimedia video and audio, game sites or mobile applications, CDN will intelligently assign scheduling domains.

High-defense cdn provides business support to meet the needs, comprehensively speeding up the site. Publish the source content to the edge node, cooperate with the accurate scheduling system; assign the user's request to the most suitable node, so that the user can obtain the required content with the fastest speed, effectively solve the congestion situation of the Internet network, and improve the response speed of user access.

The above is an introduction to high-defense cdn acceleration.
