Abstract：In this paper, we propose a bandwidth allocation scheme that is applicable to the
integrated service satellite broadcast network. Based on the study of service categorization and their QoS requirement, the scheme is a new hybrid one which combines priority queuing and adaptive minimized cycle round robin. Simulation results show that the proposed scheme can meet the QoS requirement of services in the integrated service satellite broadcast network.
Key words：satellite broadcast network; bandwidth allocation; QoS
