Bill, The problem is in defining what is "normal" and "reasonable" when customers only know what those mean in regards to their behavior and not the larger customer base nor the behavior of the global network. I work with hundreds of access providers in North America, the Caribbean, and Europe so I've pretty much all of the current approaches to this and none of them work very well IMO. I have a customer on the west coast that has a very large Asian immigrant population and a very high percentage of the traffic from this access provider is going to and from Asia. This introduces a lot of variables that are far outside of the operator's control, so what's reasonable for this operator to do to ensure "reasonable" speeds when the links to Asia get saturated far upstream of them? They certainly could choose to buy alternative connectivity to that region, but then they'd have to raise rates and most of the time that extra connectivity isn't needed. BTW, the operator in this example has plenty capacity inside their DOCSIS and FTTH plant as well as plenty of capacity to two Tier 1 carriers.

I have to take exception to your example.
Water, gas, and to a great extent electrical systems do not work on oversubscription, ie their aggregate capacity meets or exceeds the needs of all their customers peak potential demand, at least from "normal" demand standpoint.
Hi Scott,
Do you propose that Internet access service should NOT be expected to meet peak "normal" demand? That would certainly make ISP operating models unique among public utilities.
