at BGP level, when an AS is DDoSed with a 10Gbps rate (or maybe more),
/usually/ there is a lot of gear inside an ISP that becomes unresponsive
before it can reach an iptables/firewall/ddos-mitigation box

so, dealing with iptables to sort out some local rate-limit effect
(until the pipe is not full) is ok, but it's useless if ASes don't
adhere to BCP38 or if they don't deploy BGPSec (for instance)
