"A Survey on Caching and Replication on the Internet"

By Mr. Loukopoulos Athanasios


Abstract:

With the commercialization of the Web, clients abandoning their
connections due to excessive downloading delays translate directly to
profit losses. Hence, minimizing the latency perceived by end-users has
become the primary performance issue comparing to more traditional ones,
such as server utilization. In this paper we survey research on the two
most promising techniques to improve Web responsiveness namely, caching
and replication. We begin by arguing on their complimentary roles for
decreasing client perceived response time and proceed by illustrating the
main topics that affect their successful deployment on the Internet. We
analyze and characterize existing research in each of the issues,
providing taxonomies for some of them. Through our discussion certain open
problems and research directions reveal themselves.
