About IP Multicast
Note Controlling the transmission rate to a multicast group is not supported.
At one end of the IP communication spectrum is IP unicast, where a source IP host sends packets to a
specific destination IP host. In IP unicast, the destination address in the IP packet is the address of a
single, unique host in the IP network. These IP packets are forwarded across the network from the source
