Abstract
A satellite communication system which performs multicast switching on data cells. A switch receives the data cells at a set of input ports IP and directs those including a multicast routing code to a first set of output ports OP or OP . The switch also directs data cells effectively omitting the multicast routing code to a second set of output ports OP . One or more multicast replication modules are coupled to the first set of output ports and replicate data cells requiring multicast processing. During the processing, the multicast routing code is effectively omitted and the replicated cells are coupled to input ports IP or IP so that the replicated data cells are transmitted to the second set of output ports OP . An outbound processing module is coupled to output ports OP for processing the data cells for transmission over a satellite downlink transmitter
