It's a mathematical truth for any topology that you can reduce to a black box
with one
Same concern I mentioned with Jim's message. I was not clear what I meant by
"pacing" in the context of optimization of latency while preserving throughput.
It is NOT just a matter of spreading packets out in time that I was talking
about. It is a matter of doing so without reducing throug

not discard* packets. Non-discarding queues don't exist in the real
world, of course

This really speaks to the difference between cross-traffic induced delay and
self- induced delay.
There are several toolkits that can be brought to bear, and we must be careful
to examine the impact of each of them. The one that we tend to think about most
(at least recently) is the AQM algorit
