A mesh topology DVB-S network architecture for node interconnection, featuring QoS capabilities

This paper proposes a prototype mesh topology network architecture based on regenerative DVB GEO satellites, which enables the interconnection of heterogeneous terrestrial distribution nodes to each other, with minimum possible delay and offering maximum spectral efficiency of the satellite transponder. A dynamic bandwidth management mechanism, applied directly on the DVB-S stream is proposed which enables the provision of interactive IP based multimedia services at a guaranteed QoS. An actual transparent GEO satellite was used in order to create an emulated DVB-S regenerative environment and validate the performance of the network architecture, the interoperability of the heterogeneous networks and the bandwidth management mechanism.
