Perhaps Linkers have seen this already.
Huberman and Lukose report on a model of Internet congestion, in an article
last month in Science [Huberman, B.A. and Lukose R.M., Social Dilemmas and
Internet Congestion, Science, vol 277, 25 July 1997, p 535]
They present a model based on assuming the public good will be consumed
greedily if users are not charged in proportion to their use, and that this
will lead to congestion patterns with predictable statistical properties.
Their model is borne out by measurements of latencies in ping packets
bewteen the US and UK.
The model predicts that "congestion problems as presently experienced by
Internet users would disappear if individuals were charged in proportion to
their bandwidth consumption."
This idea is not new, but it's nice to see a model that matches the real
world, and some predictions from it.
