  abstract =	 "Research prototypes of networked systems are often evaluated
		  on overlay testbeds and emulation testbeds.  Most of the
		  strengths and weaknesses of these two types of testbeds are
		  complementary.  We outline the motivation, design,
		  implementation, and sample results of an environment that
		  seeks to provides the best of each type.  Flexlab couples an
		  emulation testbed with arbitrary network models.  We also
		  present a novel modeling technique tuned for this
		  environment, {\emph{application-centric Internet modeling}}.
		  The key idea is to monitor the application's offered network
		  load within the emulation testbed, replicate that load on the
		  overlay testbed, measure the path's characteristics through
		  analysis of the traffic, and use those to shape the emulated
		  network."
