Where link rates become key is in modeling the worm's dynamics. Because
often a single infected machine could fill an access link, additional
infections behind that same link didn't change the worm's overall scanning
rate; this is unlike other, non-"bandwidth-limited" worms, and changes
Slammer's growth to not be the usual exponential/logistic curve.
See our paper on Slammer for more details:

We're now trying to explore that effect, which requires knowing what those
bottleneck bandwidth rates were for sets of hosts behind a common bottleneck.
