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 impacts.
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.
Appeared in Proceedings of the 2006 USENIX Annual Technical Conference, pages 363–368, Boston, MA, May–June 2006. Short paper.
The slides from the USENIX 2006 presentation are also available, and so is our poster.
