Unicast/Multicast MAC
Multicast filtering improves the performance of networks that carry multicast traffic. This section will
explain what Multicast and Unicast are as well as their benefits (see Figure 2.53).
- Unicast:
This type of transmission sends messages to a single network destination identified by a
unique MAC address. This method is simple with one source and one destination.
- Multicast:
This type of transmission is more complicated. It sends messages from one source to
multiple destinations. Only those hosts that belong to a specific multicast group will receive the
multicast packets. In addition, networks that support multicast send only one copy of the
information across the network until the delivery path that reaches group members diverges. At
these diverging points, multicast packets will be copied and forwarded. This method can manage
high volume traffic with different destinations while using network bandwidth efficiently.
