In this paper, the service work reservation method for the efficient service differentiation and the bandwidth arbitration for the fair service allocation among access nodes are fully studied. In the polling based generalized TDM networks, QoS (Quality of Service) based multiple service is achieved by the reservation based service scheduling as well as the class based packet scheduling. These are tightly coupled with each other in every protocol step and determine the final performances of multiple service. For the seamless fair service, we propose the service quality pre-engagement (SQP) scheme and the equal weighted fair bandwidth arbitration (EWF-BA) mechanism. These make the thread based fair service allocation among access nodes possible while the class based service differentiation is maintained. The analytic and simulation results reveal that proposed mechanisms efficiently guarantee the QoS based multiple service with high network performances and the service fairness.
