Abstract: This paper proposes a novel scheduling strategy for broadband multimedia satellite networks. It is composed of the ground local scheduler and on-board global scheduler. Because most of the complexity that is added to the satellite network is confined to the ground segment, the scheduling strategy minimally affects the design of the on-board processing(OBP). Simulation shows that it is a highly efficient scheduling strategy which not only reduces the end-to-end delays endured by the best effort connections but also minimizes the degradation of VBR and ABR connections with increased frame utilization performance.
