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. -- Simon.
