Abstract
Simulation has become the evaluation method of choice for
many areas of computer networking research. When designing
new or revised transport protocols, queuing methods,
routing protocols, (just to name a few), a common approach
is to create a simulation of a small to moderate scale topology
and measure the performance of the new methodology as
compared to existing methods. We demonstrate that simulation
results using this approach can lead to very misleading,
and even incorrect, results. The interaction between the
large number of variables in these simulations can lead to
results that vary widely from between different simulation
topologies. We give empirical evidence showing different
conclusions when the same comparisons are done using
differing topologies. We argue the need for a standardized
taxonomy of simulation topologies that capture a significant
and realistic range of values for the various variables that impact the performance of a simulated network.
