I may be off base here.  Can't an ips look at the traffic; say on 443

router be taken, if available and sensible including network outage or
DDOS, than a hard block.  A quick block to mitigate and then an IPS rule

and you have an IPS that works on oc-192 SONET links? what about the
coming oc-768?
