Why is that?

Just guarantee each user a data rate that depends on how much he pays.
Charge him by what it costs you to build and maintain that much
capacity. Lots of mechanisms exist to do this: token bucket, etc.

He gets more than his guaranteed capacity only when others don't use
theirs. Otherwise he won't. If that's unacceptable to him, then he has
the choice of paying you more to upgrade your network or waiting for
others to stop using their guarantees.

It costs you nothing to let people use capacity that would otherwise go
to waste, and it increases the perceived value of your service. Your
customers will eventually find themselves depending on that excess
capacity often enough that at least some will be willing to pay you
more to guarantee that it'll be there when they really want it.


We've forgotten the Committed Information Rate already?
