Important to differentiate between the two. I'd call the former totally unacceptable, and actionable per SLA 'till resolved (besides, whoever got taken down by a multi-gigabit PING FLOOD?); the latter is
seen them.. they can be painful :( a former customer got some large/fragmented icmp flood during a may-day event as I recall.
a concerned provider appropriately covering their base (I'd police random ICMP to even less, say 128kb).
at 1mbps rate-limited customers complained that 'your link is dropping packets' (when they do a rapid-ping off their edge device with 4000 byte packets... which went over the 1mbps policer). There's certainly some limit to be used, somewhere between 128k -> 2-4mbps. Also, it highly depends on edge platform of course :( -Chris
