Bench style Network Research in an Internet Instance Laboratory Paul Barford and Larry Landweber Computer Science Department University of Wisconsin Madison 1210 West Dayton Street Madison, WI 53706 {pb,lhl}@cs.wisc.edu Abstract Network researchers employ a variety of experimental methods and tools including analytic modeling techniques, simulators, and widely deployed measurement infrastructures. It is natural to assume that the overall scope of network research may be limited by the type and capability of the tools and test systems that are available. In this paper we describe a new, bench style approach for conducting network research that we argue is essential for effectively investigating different classes of important problems. We describe the architecture for the workbench environment that enables this approach -what we call the Internet Instance Laboratory (IIL). The conceptual model for an IIL is a highly con gurable laboratory environment containing commercial networking equipment typical of any end to end path in the Internet. An IIL would also have the capability to create accurately a broad range of conditions across all networking layers. The two most important advantages of an IIL are the ability to instrument entire end to end paths and the ability to install new equipment or
