Towards Optimized QoS Based – Charging Model

AbstractـѧѧــــThis paper proposes a pricing model for Differentiated Services (DiffServ) network. The service differentiation is modeled according to the guaranteed QoS level for each class. This model assumes that a user selects an appropriate class of service depending on his QoS requirements. The users access to the service is assumed as bursty traffic, and all the users are competing on one shared bandwidth. The equivalent guaranteed capacity of a class is calculated according to its guaranteed QoS level. A fixed price is given for each class for certain guaranteed capacity. Then, an analysis for the service provider to achieve maximum value of revenues is made by determining the total required shared bandwidth, the service class optimum guaranteed capacity and its optimum price
