Kevlar: A Flexible Infrastructure for Wide-Area Collaborative Applications
Abstract : While Web Services ensure interoperability and
extensibility for networked applications, they also complicate the
deployment of highly collaborative systems, such as virtual reality
environments and massively multiplayer online games. Quite simply, such
systems often manifest a natural peer-to-peer structure. This conflicts
with Web Services' imposition of a client-server communication model,
vectoring all events through a data center and emerging as a performance
bottleneck. We design and implement the Kevlar system to alleviate such
choke points, using an overarching network-overlay structure to
integrate central hosted content with peer-to-peer multicast. Kevlar
leverages the given storage and communication models that best match the
respective information: data most naturally retrieved from the cloud is
managed using hosted objects, while edge updates are transmitted
directly peer-to-peer using multicast. Here, we present the Kevlar
architecture and a series of carefully controlled experiments to
evaluate our implementation. We demonstrate Kevlar's successful and
efficient support of deployments across wide-area networks and its
adaptivity and resilience to firewalls, constrained network segments,
and other peculiarities of local network policy.
