This paper introduces a novel operational framework for the problem of time slot assignment in a Digital Video Broadcast-Return Channel via Satellite (DVB-RCS) system. The approach is compliant with the latest technical specifications emitted by the European Telecommunications Standards Institute (ETSI) about Quality of Service (QoS) in Satellite Earth Stations and Systems (SES). It is a cross-layer MAC-PHY optimization approach sustained by the powerful framework of convex optimization. The paper proposes a hierarchical dynamic bandwidth allocation approach, which is motivated by the computational complexity of the single-step solution. More specifically, we obtain and analyze the optimal time duration of the time slots and jointly, we make a fair allocation of slots to areas, which is the highest level in the bandwidth allocation hierarchy. Results show up to a 10% increase in transported capacity.
