Multicast applications
In the majority of cases, a frame is sent with a unicast address to a particular receiver. If
an application sends the same data to several receivers, the amount of data can be
reduced by sending the data using one multicast address. For some applications (e.g.
NTP), there are fixed multicast addresses.
