The Internet is an amazing achievement - any of the thousand million
hosts can freely use any of the resources anywhere on the public
network.  At least that was the original theory.  Recently issues
with how these resources are shared among these hosts have come to
the fore.  Applications are innocently exploring the limits of
protocol design to get larger shares of available bandwidth.
Increasingly we are seeing ISPs imposing restrictions on heavier
usage in order to try to preserve the level of service they can offer
to lighter customers.  We believe that these are symptoms of an
underlying problem: fair resource sharing is an issue that can only
be resolved at run-time, but for years attempts have been made to
solve it at design time.  In this document we show that fairness is
not the preserve of transport protocols, rather the design of such
protocols should be such that fairness can be controlled between
users and ISPs at run-time.
