Estimating delay distribution

The one-way delay results obtained by the tool may be used to estimate a best distribution for characterizing the behavior of this metric during the experiment. Using the simple method of moments, parameters of the distributions are estimated. The distributions estimated are plotted beside the trace collected in the attempt to identify the best distribution for characterizing this collection. A simple example of this estimation is shown in Figure , where only three distributions were used. Methods like mean squared error have been implemented to aid in identyifing the distribution with best fit.
