Hi Kathie, [long time, no see :-)] I'm well aware of the CoDel paper and it really does a nice job of explaining the good queue and bad queue properties. What we found is that loss-based TCP CCs systematically build standing queues. Their positive function is to keep up the link utilization, their drawback is the huge queuing delay. So everyone not aware of both papers should read them. However, if you think something that I wrote is NOT in accordance with your findings, please let me know.
