I did a very cursory check to see if this was already brought-up but
may have missed it. Folks interested in addressing highly variable
delays in networks and such may find the "codel" AQM interesting. It
seeks to keep the time packets spend in queues down as part of
addressing "buffer bloat."
It won't eliminate variable delays and jitter but if it and/or things
like it get more widely deployed it may constrain them a bit.

I bought a NetGear 3800 a couple of weeks ago in order to run the
CeroWrt test release which is used to verify codel.
So far it works well here, but I have a 50/50 fiber connection
(delivering at least 45-48 Mbits in both directions) so I don't see
much buffering in my end of the network.

PS. I attended a presentation by Jim Gettys, the BufferBloat Man, in
April: The story about how van Jacobsen could not get his new AQM
paper accepted to any refereed conference is both sad and funny:
The paper was dismissed with the comment that "it has to be wrong" and
"the author would do well to read the definitive paper by van
Jacobsen". :-)
I read somewhere that "authorities" in the region were positively
denying the possibility of manned flight for at least 5 years after the
Wright Brothers were demonstrating the airplane. What's that old saying?
When someone comes up with a revolutionary idea,
First they're mocked,
Then, it could be true,
Then, it's accepted, (sometimes after the originator's death)
Then, others say they discovered it first.
Sincerely,
Ron
