CDN Overview

Content Delivery Network (CDN) is an intelligent virtual network constructed based on the existing network. It uses edge servers deployed in different areas and functional modules such as load balancer, content distributor, and content scheduler on the central platform to enable subscribers to obtain required content from the nearest node, reducing network congestion and improving the access response speed and hit rate.

CDN consists of multiple components. In this deployment, LVS, Nginx, and ATS are used. This document describes the optimization method of each component to achieve optimal performance on the Kunpeng server.
