Abstract 1
Today, most of the popular web sites are served from
single locations. This basic Web client­server model
is easy to deploy and maintain and thus is very
successful. It suffers, however, from several efficiency
and availability problems. This paper presents
Walrus, a low­latency, high­throughput Web service
that addresses some of these problems. Under
Walrus, a single logical Web server can be replicated
to several clusters of identical servers where each
cluster resides in a different part of the Internet. An
important aspect of Walrus is its ability to
transparently direct the web browser to the best
replica without any changes to the web server, web
