Hierarchical packet scheduler for supporting fairness and QoS over DVB-S2 ACM systems

In this paper, we propose a hierarchical scheduler offering fairness and QoS for DVB-S2 ACM systems while minimizing the decrease of throughput. As a result of the simulation, we show that the proposed scheduler supports bandwidth fairness to the individual RCST and can provide some level of QoS differentiation for user traffics.
