Rob Kiefer will present his research seminar/general exam on
Thursday May 24 at 9AM in Room 402. The members of his
committee are: Michael Freedman (advisor), Jen Rexford, and
Margaret Martonosi. Everyone is invited to attend his talk
and those faculty wishing to remain for the oral exam following
are welcome to do so. His abstract and reading list follow
User devices are being used in increasingly diverse ways and
conditions, and are connected to increasingly diverse network
resources. Different conditions call for different network resources
to be used (e.g., using cellular connectivity when away from Wi-Fi
access points), and different resources come with varying restrictions
(e.g., monthly data caps) that determine how and when they should be
used. In addition, users carrying these devices are increasingly
mobile, which means that the best network resource to utilize can
change relatively quickly. Today, this decision process is typically
done manually by the user, which is both clumsy and suboptimal.
In this work, empowered by the new Serval network stack that supports
transparent connection migration, we design and prototype a framework
that allows users or applications to write network policies against a
library containing system conditions such as battery statistics,
interface statistics, and ongoing network flow statistics. This
framework provides a coherent solution for determining how a device’s
network resources should be used on a per-flow basis. The framework
continuously evaluates each flow against a policy, which determines
what action to take on the flow (e.g., “migrate this flow to Wi-Fi”).
Policies are expressed as scripts to allow them to be flexible and
expressive. We evaluate several different sample policies on our
Android- and Linux-based prototype, including one for resilient
connectivity, for minimizing latency, and for maximizing throughput.
