Those price mechanisms are possible on connection-oriented networks, such as
X.25 and ATM networks.
On connection-less networks such as IP networks, the source will always have
the right to send traffic; packet filtering and traffic shaping can cut some
of the possibly unwanted traffic, but not all of them.
