Worse, typically the impact to our own network as the whole may become significant as properly.

Broadcasts tend to effect in more messages, and if serves around the network carry on to answers broadcasts with broadcasts, we all end up with a broadcast tornado. Broadcast storms start small, but simply like a snowball, they will end upwards being very major – so big that normal network operations are compromised and/or prevented!
