Yea, that one is pretty sad.
It still remains a field of active academic research:

Lacking competition in general, doesn't help.
What I am actually more frustrated about is the network neutrality
advocates A) conflating "buffering" with malfeasance, rather than a
and B) Using politics rather than technology to attempt to achieve
their goals. If *only* a few prominent members of that side of affairs
"got" that some better technology, deployed, might solve some of their
problems and make the internet better for everyone, we'd make more
fq_codel is a uniquely "american" algorithm, in that it gives the
"little guy" a little boost until it achieves parity with everyone

My principle observation is that with the changes in traffic patterns
in the last decade, and the predominance of application-rate limited
streaming, that most
folk are merely forced into a bandwidth tier that is less rarely
annoying. This does not of course solve the corporate gateway problems
very well, nor does it truly kill it dead, but until that day when
"the right stuff" is readily available, and more informed demand
I was sad to see recently a cisco white paper that even ignored their
own work on pie.

Heh. I have essentially abandoned the IETF as the inmates are running
the asylum, and trying to continue to make our points there was
- and out of my budget. I'd rather stay home and get better code out
the door. Or come up with some other set of orgs to annoy into paying
I would not mind going to another IETF meeting to give a preso (on,
say, cake), but I'm unwilling to front the funds or time anymore.
