We design a QoS-oriented pricing architecture with multiple delay levels and bandwidth supports. In contrast to previous work in pricing Internet, our QoS pricing architecture considers prices charged for the resources with queueing theory characteristics. Our pricing strategy adopts load-based cost function to make the resource distribution more efficiently. In this paper, QoS routing algorithm and admission control utilize the cost to find a suitable path. Simulations show that load-based cost function helps to avoid congested links and to make traffic load balancing automatically.
