ABSTRACT:
In a communication system using multicasting, multicast packets are forwarded through a switch by destination ports after these ports receive the packets. A source node sends the multicast packet to a subset of nodes within the multicast group, which in turn, forward the multicast packet to other subsets of packets within the multicast group that have yet to receive the information. This is continued until all ports within the multicast group have received the information.
