Abstract:
Content Distribution has emerged as a preferred way to improve the client
perceived response time of applications and services provided over the
Internet. In this paper, we analyze the reduction in response time that
can be obtained by deploying a content distrution network solution. We
study the impact of caching hit ratios on content distribution, and its
interaction with network latencies. We then examine the implication of
the size of the content distribution network to study the relative merits
of two approaches towards building such neworks: one using a small number
of powerful sites; and, the other using a large number of less powerful
sites. We also analyze the optimal distribution of processing capacity
between an origin site and surrogatge sites in a content distribution
enviroment.
