TCP Congestion

Via Slashdot: Fixing the unfairness of TCP congestion control

A nice article on the logic behind traffic management on the internet. If only we transportation engineers could simply drop packets (analogous to a helicopter vaporizing cars that were in queue?) The problem of course is that bandwidth use is not charged at marginal cost when it is in the congesting region, leading to overconsumption. The issue is the transaction costs associated with implementing a charging regime.
