RED alone doesn't help much against flooding attacks. You'd need
something like "RED with penalty box" or (flow-based) WFQ, and those
are either in research status or have other fundamental problems.
Don't get me wrong, RED is extremely cool - buy only routers that
support this at line rate, and configure it on any interface where you
expect even a slight chance of congestion.
