seen them.. they can be painful :( a former customer got some
large/fragmented icmp flood during a may-day event as I recall.

at 1mbps rate-limited customers complained that 'your link is dropping
packets' (when they do a rapid-ping off their edge device with 4000

some limit to be used, somewhere between 128k -> 2-4mbps. Also, it
highly depends on edge platform of course :(
