Integrated Scientific Workflow Management for the Emulab Network Testbed
Eric Eide, Leigh Stoller, Tim Stack, Juliana Freire, and Jay Lepreau, University of Utah
The main forces that shaped current network testbeds were the
needs for realism and scale. Now that several testbeds
support large and complex experiments, management of
experimentation processes and results has become more
difficult and a barrier to high-quality systems research. The
popularity of network testbeds means that new tools for
managing experiment workflows, addressing the ready-made
base of testbed users, can have important and significant
We are now evolving Emulab, our large and popular
network testbed, to support experiments that are organized
around scientific workflows. This paper summarizes the
opportunities in this area, the new approaches we are taking,
our implementation in progress, and the challenges in
adapting scientific workflow concepts for testbed-based
research. With our system, we expect to demonstrate that a
network testbed with integrated scientific workflow
management can be an important tool to aid research in
networking and distributed systems.
