Additional Results

Abstract

So far in this book, we have presented results for a complete set of experiments using four connection structure models and three RTT models, in both unconstrained and constrained network link modes, using two different input traces. In this chapter, we present some additional results from experiments we conducted in the process of completing this study. For all experiments discussed in this chapter, we used only the UNC traffic as input. While these experiments are not central to our overall results, we have included them here for completeness. We present these results in three sections as follows. In Section 6.1, we present results for a small set of experiments using three RTT models we developed (explained in Chapter 3) – nodelay, medianRTT, and uniformRTT. For each of these RTT models, we ran experiments using only the control set (the a-t-b-t connection structure model with the usernet RTT model). In Section 6.2, we present results for the DA (discrete approximation) RTT model, showing that its results closely follow that of the usernet RTT model.

Discovery consists in seeing what everyone else has seen and thinking what no one else has thought.
