This paper describes a control mechanism for a
future Internet. It is an economic mechanism that enables users
to choose different pairs of price/QoS priority levels for network
services at the user time scale. User time scale means that prices
vary at a rate suitable for human beings to respond to those
price changes. The changes might happen on an hourly, daily, or
weekly basis. We believe that such an economic control
mechanism at medium time scale, which is coupled with a
technical rate control mechanism at a short time scale, is a
simple and cost-reducing system that can provide quality of
service to end-users. We show that the approach proposed
enables network service providers to react to network congestion
appropriately and provides end-users with high flexibility in
service selection. After discussing different Internet pricing
principles, we describe the market-managed test network, the
QoS pricing and charging software for network services, and the
experiments run on a DiffServ network. We present a theoretical
model based on Markov chains that can represent the proposed
market-managed network. Finally, we present results from the
analysis of the theoretical model as well as measurement results
from the DiffServ network. We show that the behavior of such a
system depends on the user’s net benefit, the prices for the
network services, as well as on the heterogeneity of the user pool.
