Abstract de la publi numéro 4072

This article proposes a new approach of IP multicast networks using a geostationary satellite. An overview of the current use of satellite for internet is presented. It underlines the interaction between the network and access levels and shows the limits of the current solutions i.e. the use of a transparent payload and the Multi Protocol Encapsulation (MPE). Then, alternative solutions are proposed, presenting the use of an on-board intelligence and of a more interactive standard than the DVB-S, the DVB-RCS. This article sets out to study a system conveying multicast streams with an on-board switch. We study here the implementation of both an encapsulation and a signalisation adapted to the system. Eventually, as food for, thought the adaptation of terrestrial protocols in this framework is brought up.
