Reverse proxy caches are used to provide scalability and
improved latency to popular sites on the Web. In this paper
we provide analytical performance models for distributed
reverse proxy cache architectures, and study the trade-offs
between various design alternatives. Specifically, we consider
static and dynamic assignment of proxy cache nodes
to Web sites, with different levels of sharing of proxy caches
among Web sites. Innovative modeling contributions have
been introduced to handle real design constraints, such as
bounded cache size and bounded processing power, and
different characteristics related to the hosted objects, including
reference rates, popularity distributions and update
rates. In the analysis we have modeled both system steady
state as well as transient interaction between Proxy sites
and Web sites. We have found different trade-offs between
various design alternatives depending on characteristics of
the Web site workloads.
