Stability and optimization of DNS-based request redirection in CDNs

Abstract

Content Delivery Network (CDN) solutions have been progressively integrated to many network infrastructures. However, they show technological limitations when dealing with an increasing number of bandwidth-hungry and demanding applications. One of the most effective ways to improve the performance of a CDN is to efficiently manage its traffic by implementing relevant request routing solutions. To this end, we present in this paper a flexible scheme and an optimization algorithm, based on Lyapunov theory, for request routing in CDNs. Our online approach provides a stable quality of service to clients, while improving content delivery delays. It also reduces data transport costs for operators and outperforms existing techniques in terms of peak traffic management.
