The current Internet was originally designed to provide best-effort data
transport over a wired infrastructure with end hosts utilizing a layered
network stack to provide reliability, quality of service, security etc.
for user applications. However, the proliferation of inelastic
applications, coupled with wide spread migration towards hybrid networks
utilizing wired and wireless links and the plethora of end host variants
ranging from cell phones to enterprise servers necessitates the migration
of more and more services away from the edges and into the network. The
aim of this thesis is to provide a generic and flexible framework and
associated algorithms that will enable the incremental deployment of
intelligent services into the network with the aim of optimizing the
end-user experience for networked applications. We focus our research on
two key facets; cross layer optimization algorithms to enable efficient
transport of data across a hybrid network coupled with the inclusion of
semantic information in the data packets that can be intelligently
processed within the network. The aim is to show that if routers in a
network have visibility into the type of data that they are currently
handling (either at a packet level or a flow level), the routers can then
perform optimizations and content adaptations relevant to that specific
type of data based on local policies. We intend to use RDF/RDFS as the
medium to convey this semantic information thereby allowing interim
routers to reason over their existing knowledge base on how to
specifically handle a given data packet or stream in a flexible and
generic manner. Mechanisms to incrementally deploy our framework into a
large scale network along with the implementation of new value added
services that can now be offered will be demonstrated using a large scale
testbed. Start Date: July 2005 End Date: December 2007 Faculty:
