The paper studies a protocol and a control architecture aimed at implementing bandwidth and call admission optimization over a DVB Return Channel Satellite Terminal (RCST) under Quality of Service (QoS) constraints. The approach can be applied in all cases where traffic flows, coming from a terrestrial portion of the network, are merged together within a single DVB flow, which is then forwarded over the satellite channel. The exact bandwidth to be provided to the flows entering the DVB layer is unknown because equivalent bandwidth techniques guarantee only approximate solutions in heterogeneous conditions.
