> I would be very hesitant to introduce a sorting proxy > fair queuing is a good idea for the majority of production services Huh? As you've said, fair queuing requires one to quickly look at incoming messages, decide whether they are high/low-priority and route accordingly (to the processing server/to the queue). This is a sorting proxy, and so it seems that having it in some form is required to implement fair queuing. Right? > It’s absolutely great when a misbehaving client only DoSes themselves and doesn’t affect anyone else. Yes, of course. But that's precisely the problem with DoS/DDoS attacks: they're, inherently, the cases of a client/clients refusing to obey the back pressure demands from the upstream. Over network, a misbehaving client affects also affects their ISP at the very least, by the way.
