Abstract
We present the design of a new distributed Web caching infrastructure
that uses network-level mechanisms to provide routing of
Web requests to caches. Our work is motivated by the need to provide
effective caching not only for the small number of extremely popular
Web documents, but also for the large number of documents of only
intermediate popularity. In currently existing and proposed systems,
requests for less popular documents suffer from long latency stemming
from the inefficiencies of routing through an application-level
overlay network. We combat this problem by integrating cache routing
into the network layer, which results in shorter search paths and
fewer application-level checks.
