A Pricing Model for Networks with Priorities

In this paper, a centralized resource allocation model based on priority schemes is first proposed for best-effort networks in which traffic from all priorities are fully multiplexed. Then a priority pricing scheme is used to distribute the resource allocation process. Users and the network exchange their characterizations on QoS, resource demand and prices via contract negotiation. The contract negotiations take place among three network layers: users, priority classes and the network, in a distributed and dynamic fashion.
