7.9.2.12 Multicast
The multicast interface is shown as in Figure 7-46.
Multicast is a transmission mode of data packet. When there is multiple-host to receive the same
data packet, multiple-cast is the best option to reduce the broad width and the CPU load. The
source host can just send out one data to transit. This function also depends on the relationship of
the group member and group of the outer.
