A survey of cache placement algorithms in content delivery networks

Abstract

This paper analyzes cache deployment algorithms in content delivery networks (CDN), which are important for increasing content delivery speed, reducing network traffic, and ensuring scalability. A CDN is a geographically distributed network infrastructure, which is placed on the Internet and is aimed at reliably delivering content to users, as well as reducing traffic on the networks of communication operators. A content delivery network serves as an important element in today’s internet infrastructure to ensure fast and secure delivery of content around the world. When using a content delivery network, it uses local cache servers to keep copies of content on a central resource server closer to end users. This reduces latency and increases content delivery speed. Cache placement algorithms determine which cache server to store content and where to place it. As the demand for high-quality content continues to grow, caching algorithms play an increasingly important role in efficiently delivering content to users around the world. This article analyzes caching algorithms in CDNs, including their advantages, disadvantages, and application areas.
