Validation of a QoS architecture for DVB-RCS satellite networks via the SATIP6 demonstration platform
Full integration of satellite technology in future terrestrial infrastructures requires support for high-quality broadband bi-directional communications. Research efforts in the field of satellite communications are currently oriented in the study of QoS-aware solutions for DVB-S and DVB-RCS which allow seamless deployment in the Internet. In this paper, the QoS architecture of the SATIN project, sponsored within the 5th EU Research Programme Framework, is presented, along with the implemented demonstrator and the obtained results. The QoS architecture is organized into two main modules, the Traffic Control and Access Control modules, whose aims are (i) to provide for differentiated service of conveyed IP flows and (ii) to achieve efficient utilization of uplink bandwidth, respectively. Experimental results obtained through the developed demonstration platform are reported and discussed to assess the effectiveness of the designed solution in terms of both service differentiation and efficient utilization of satellite resources.
