If the Muticast case, if we have a terminal wich join Group G but
doesn't want the data from the source S. So, in this case, we don't need
to transmit data in the uplink of the satellite network, and so we
reduce the no need traffic. into doing that, we have to know the source
adress (PIM-SM and the Rendez-vous Point RP).
