Abstract
We present an architecture for combining two
established network paradigms, IP and Disruption-Tolerant
Networking (DTN), into a unified packet gateway design that
leverages the advantages of both. Vehicular networking (VNET)
scenarios often involve brittle links between communicating nodes
due to their mobility. DTN solutions, by using a dynamic hopby-
hop delivery model instead of the end-to-end IP model, are
able to sustain a large class of applications despite intermittent
links. As a defining characteristic, our design is applicationtransparent
in that it requires no changes to host applications
(or the underlying host protocol stacks) in order for them to
use DTN transport when IP is not feasible. In addition, we build
into the architecture an explicit disruption notification service for
keeping users informed as well preventing application time-outs
during an IP outage. Finally, given the wide range of behaviors
exhibited by applications that can benefit from DTN, our design
supports the notion of an application lattice to allow operators
to customize, on a per application/group/protocol basis, how the
switch between IP and DTN and the disruption notification are
performed. A preliminary evaluation based on a C++ proof-ofconcept
implementation has illustrated several potential benefits
of the proposed architecture for VNET applications.
