Wrong.  The attacker just programmatically generates semantically-valid traffic which is indistinguishablle from real traffic, and crowds out the real traffic.

All those fancy timers and counters and what-not don't matter.

I've seen it done over and over again.  Why some folks seem to think this is theoretical or that I somehow haven't thought of something they think will prove to be a magic solution is really beyond me, heh.
