This paper studies the issue of pricing delay-sensitive services in a DiffServ backbone network. A bandwidth manager agent is introduced into the QoS provisioning and pricing architecture. In the core routers, it reserves per-class bandwidth in bulk and, in the edge routers, it admits individual delay-sensitive services to the reserved bandwidth. Additionally, the paper proposes a QoS-aware flat pricing strategy for charging delay-sensitive applications in the DiffServ backbone networks. Combining the QoS provisioning mechanism and the QoS-aware flat pricing strategy enables economic efficiency and optimality in the DiffServ backbone network, which has been demonstrated by simulations.
