We present Riptide, a distributed, cooperative Web caching
system. Riptide distributes nodes throughout the infrastructure to
serve and manage Web content. Riptide is constructed on the
OceanStore distributed storage system and inherits OceanStore's
scalability and self-configuration. Nodes may be added or removed as
desired. New resources are integrated and begin serving requests
automatically; attempts to access unavailable resources are
transparently routed to alternative providers. Because the underlying
system supports mobile data, copies of content may be moved without
expensive directory update protocols. Consequently, the load of
serving documents may be quickly redistributed to any of the nodes in
the underlying system. We describe the architecture of Riptide and
present a preliminary performance evaluation of the implemented system
running under a simulated workload.
