Load balancing in Content Delivery Networks in Novel Distributed Equilibrium

In today's world's to provide service to netizen's with good availability of data, content delivery networks (CDNs) must balance requests between servers while assigning clients to closet servers. In this paper, we describe a new CDN design that associates artificial load-aware coordinates with clients and data servers and uses them to direct content requests to cached data. This approach helps achieve good accuracy and service when request workloads and resource availability in the CDN are dynamic. A deployment and evaluation of our system on Planet Lab demonstrates how it achieves low request times with high cache hit ratios when compared to other CDN approaches.
