Keynote 2: Massive-Scale Parallel Network Simulations, Past, Present and Future by George Riley

Discrete event simulation tools for analyzing performance of computer networks have been available for decades, dating back to the early days of the venerable ns-2, continuing through GTNetS, SSFNet, ROSSNet, and most recently ns-3. At each step along the way various developers and researchers have reported on "large-scale" simulation experiments using these tools. As the available hardware platforms grow in scale, the scale of network simulation experiments have grown similarly. In this talk, we will discuss the various reported "large-scale" or "massive-scale" experiments, the approach used to achieve the larger scale and the drawbacks of the experiments. Finally, we will try to look a bit in to the future to see where this field might be in the coming years.
