Re: does the multicast saves process only?? or it save bandwidth

One of Multicasts main benefits is bandwidth savings.  without going into the differences between sparse-mode/dense-mode here is a basic example

Server1 needs to send the same data/packets to 3 hosts across 3 routers.

Instead of creating 3 separate unicast packets to each host destination, Server1 sends 1 packet to 1 multicast group address, 

R3 would recieve the multicast packet, duplicate, & send to the hosts.

      1 packet----------------------------->                                                    Host1

Server -----------> R1 --------> R2 --------> R3 ---------------------------->     host 2

                                                                 3 packets to all 3 hosts ---->   host 3

In a case where you have hundreds of hosts needing to receive traffic for a multicast group address, The bandwidth savings are tremendous especially over WAN links
