Distributed CDN Models for Improved Fault Tolerance and Resiliency

Abstract

With the growing demand for reliable and scalable content delivery, Distributed Content Delivery Network (CDN) models have emerged as a vital solution for enhancing network performance, fault tolerance, and resiliency. Traditional centralized CDNs often suffer from single points of failure, limited scalability, and vulnerabilities in the face of large-scale disruptions. In contrast, distributed CDN architectures leverage decentralized infrastructure to improve content availability, minimize latency, and optimize resource utilization across geographically dispersed edge servers. This paper investigates various distributed CDN models that focus on improving fault tolerance and resiliency, addressing challenges such as network congestion, hardware failures, and traffic surges.
