The broadcast properties and the wide coverages of the satellite are ideal for multicast applications. Unfortunately among the satellites most domestic parabolas are aimed at are not the less expensive ones. To overcome this problem we propose in this paper a relaying architecture where the sites equipped to receive the satellite transmission become relayers of the received multicast flows on the terrestrial Internet to the benefit of the sites which are not equipped with a satellite receiver.

Abstract
The broadcast properties and the wide coverages of the satellite are ideal for multicast applications. Unfortunately among the satellites most domestic parabolas are aimed at are not the less expensive ones. To overcome this problem we propose in this paper a relaying architecture where the sites equipped to receive the satellite transmission become relayers of the received multicast flows on the terrestrial Internet to the benefit of the sites which are not equipped with a satellite receiver. Also, this is done recursively, that is, the sites getting the flows will help to propagate them further. This architecture allows to overcome the restrictions suffered by multicast traffic in the global Internet.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
