In this paper we present the design and performance
evaluation of a network emulation cluster built with commodity
PCs and network switches. Each emulated node
runs inside its own virtual machine and is complete with
a kernel and device drivers and the virtual machine monitor
ensures isolation between the emulated nodes, fair access
to the resources of the underlying physical node, and
high performance. The load of traffic conditioning (emulating
packet delays, losses and other characteristics of widearea
network links) is shared between all physical nodes
by conditioning only the traffic originated by the emulated
nodes they host. The above organization results in an emulation
testbed that is low cost and scalable while providing
strict resource isolation between emulated nodes and high
emulation fidelity by allowing the emulation of kernels and
other system level software. In this paper we present the
main considerations behind the design of our testbed and
through detailed performance evaluation we demonstrate
that our approach can result in a scalable emulation system
with high performance.
