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.
