As described in section 3.3, in scenario 3 we endeavored to find the MTBBU vs. the average delay in a manner similar to [1]. The results so far are inconclusive. We believe that the deterministic approximation that we make to find the average delay is either not accurate enough or not computed properly. Also, because we must assume both that is large compared to and that must be relatively large for our approximations to hold, we expect that the MTBBU is extremely high, making it difficult to run simulations long enough to capture good data points. In the plot in figure 8 the disparities are evident. It seems that with a half second shift to the right of the analytical curves there would be agreement for smaller buffer values.
Figure 8: We plot MTBBU as a function of buffer size for , sec. seconds. This is identical to the
case given in [1] We see that the experimental results are similar
to those found by Steinbach. The analytical are shifted to the left, however.
