A RED approach would be good, but in general there has to be a limit on the queue. Your wireless interface should not become a packet long term storage facility. I've seen RTTs to the base stations on the order of 25000ms (that's 25 SECONDS) or more. If you can't deliver a packet a through 300ns distance of air in 10ms, it is probably time to drop it. Perry
