“…Multicast in multibeam satellite systems has been little investigated from the scheduling and resources allocation point of view. The authors in [11] propose to choose a fixed Reed Solomon code and a fixed rate out of a set of possible rates in order to accomplish a certain degree of reliability. Following a similar approach to [11], works in [12,13] propose to choose a modulation and codification (MODCOD) which ensures reception to a subset of the UTs in the multicast group.…”

We propose a multicast scheme for multibeam satellite systems exploiting both the multiuser and spatial diversity inherent in this type of systems while taking into account realistic physical distributions of User Terminals (UTs) over the coverage. Our proposed scheme makes use of the well-known Adaptive Coding and Modulation (ACM) feature in Digital Video Broadcasting over Satellite, 2nd Generation (DVB-S2) and Extension (DVB-S2X) standards but also incorporates a set of innovative features. First, multilink reception, that is, receivers that can syntonize different frequencies and/or polarizations, together with Network Coding (NC) is used to enable decoding of signals from adjacent beams (spatial diversity). Second, efficient and fair allocation of resources is achieved through Proportionally Fair Multicast (PFM) scheduling. Our results, obtained over realistic nonuniform UTs distributions, show average system multicast throughput gains up to 88% with regard to state-of-the-art multicast schemes. Furthermore, a complete cross-layer architecture is proposed, fully compliant with the standard providing Quality of Service (QoS) guarantees.

“…singly-layered) long-term, rate scheduling approach for multicasting bulk files over a hybrid satellite-terrestrial network [TC00]. The 'long-term' rate scheduling approach is designed for an environment in which the propagation delay is significant, and the capacity of the feedback channel is limited.…”

We propose a framework for single-source, satellite-based multicast dissemination of bulk files. The framework trades off between reception delay and bandwidth usage and coexists with terrestrial background network traffic; specifically TCP traffic utilizing a short-term congestion control mechanism. The framework consists of two major components: 1) a multicast rate scheduling mechanism that uses longterm, end-to-end multicast packet survival statistics in order to deal with the bandwidth-delay trade-off issue, and 2) a fair queueing algorithm that regulates the points where multicast traffic from the satellite meets terrestrial background traffic. We show through simulation the performance of this framework under a number of scenarios.
