The problem here is that there's no bottleneck between the queue and the output and so the AQM isn't really doing anything. I'd like to pace packets being dequeued to allow for the creation of a bottleneck where the output is the same link speed as the upstream link. Any ideas? Thanks, Iain. --=20 urn:x-human:Iain R.
