always active, we can conclude that, practically, all the gap between IBA and heuristic
algorithms is due to the bandwidth allocation granularity for every network load value.
On the other hand, in the single-bottleneck scenario, the number of sources that share
the bottleneck link is more consistent than in the other network scenarios. Therefore, the
impact of traffic prediction is not anymore negligible. This can be observed in Figures
8.1(b) and 8.1(c), where the gap between IBA and the heuristic algorithms is present for
all offered loads.
Finally, we note that, also in this scenario, the performance of the proposed dynamic
bandwidth allocation algorithms (in particular, OBA) well approaches that of IBA, espe-
cially for high network loads.
