Broadcast is the classic way to do this.
In general, it's better if possible to use multicast. The reason is
that broadcast assumes your message is so important that *every* box
on the network wants to see it. Even if that's true at time T1 it may
not be true at time T2.
Multicast is a way of sending to "anyone interest in messages of type
'foo'". If you aren't interested in such messages then you don't
enable that multicast address.
By analogy, broadcast is junk mail, multicast is a by-subscription
mailing list.
If you're doing this for a single network where you know what will be
on it, broadcast may be fine. If you want to distribute the
application to others, you really should make it a design principle
not to use broadcast.
