It would generally seem that ISPs would provide more downstream capacity than upstream, since this saves money and normally not all the downstream customers will use all their bandwidth at the same time. But a big worm could well break that last assumption.This tends to happen anyway due to statistical multiplexing, but is usually not what the customers would want if they considered the question, and is not what ISPs want if they bill by the bit. So it would seem that worms are, at a minimum, not a simple or unproblematic capacity management problem. Stuart.
