A generic satellite interworking unit (IWU) is proposed for delivering real-time traffic across an arbitrary satellite bridge employing asynchronous transfer mode (ATM). End-to-end cell transfer delay (CTD) and cell delay variation (CDV) bounds are provided by logically associating cells to short duration link-level frames. In addition, a generic scheduler is proposed for the uplink earth station (ES). This scheduler only defines the service priorities and deadlines of queued cells but does not define the particular fashion in which an ES gains access to the shared transmission medium. Simulation results demonstrate that the quality of service (QoS) can be efficiently managed in order to maximize satellite throughput of real-time traffic
