My talk last week at TTI Vanguard is now up on youtube. I used no
slides, and a bunch of new simple analogies (including the world's
most elaborate "rickroll"!) to explain the problems videoconferencing
and voice have with competing with web traffic, with bits about
cryptography, packet loss, bufferbloat, fair queueing and active queue
management across all our access technologies today, as well as some
notes as to the NTIA broadband programs and ongoing FCC measurements.

My special thanks to Len and Nancy Kleinrock, and to Lisa Yao, CEO of
TTI Vanguard, for sponsoring my talk and travel. Plug: There were a
bunch of very interesting other talks at that conference (including
one amazing one on quantum computing that went over my head
completely) that I enjoyed greatly. A huge thx also to my volunteers,
Jamie, Vasu, and Joshua, who went the extra mile to help out.

I am of course trying to reach new audiences outside our circle with
my talk, please reshare widely?

I cavort on the shoulders of giants!

I'm going to give myself an "A" for concept, but a "B" for
performance. The latter half could have gone a bit faster, and one of
the more difficult tricks, where one person already juggling tosses a
ball (new flow) to another to incorporate it into their flows, was too
hard to do, and didn't come off. Bunch of other flaws - notably I'd to
say over and over again it would be better to think about an optimum
for a low latency metaverse-capable internet would be for everyone to
think more about "steady kilobits per millisecond".

It's very hard to express how fair queuing works, also, correctly, in
the context of this talk. There are quite a few other networking
concepts that I hope could be explained in this way, the difficulties
with doing full duplex wireless using a water ballon to splatter the
reciever was originally part of the act but I cut it in deference to
the hotel staff!

> Dave, you should consider stand-up... :-)))

I've been thinking about retiring, and opening up a comedy club in
Starbase, Texas, with a marachi band on sundays.

After working on theory, code, standards, and serious publications for
so long, and being trapped behind zoom for the past 3 years, I needed
an live outlet, like this, to stretch out a bit. I miss the high speed
interactions you get out of "improv" for example, that's not a
zoom-able thing. After the conference Bruce invited me to a musical
jam which was *awesome* and also an example of what cannot presently
be done well over the present day internet. One day, I hope.

It was so great to get out and do this, and perhaps I'll do it again
one day or film it more carefully and not live.

If y'all would like a mostly serious explanation of many of the
problems wifi has (With a fun explanation towards the end of what all
OSes had been getting most wrong about wifi until then), please see
the 8 minute segment here:
https://www.youtube.com/watch?v=Rb-UnHDw02o&t=1550s or, preferably,
pass the whole thing to someone making wifi chips and drivers.

The related paper is rather dry in comparison, unless you get excited
about 10x reductions of network latency across the board in cdf plots.
https://www.usenix.org/conference/atc17/technical-sessions/presentation/hoilan-jorgesen
- a huge (and still flailing) goal for me has been to get the now
standard linux APIs for that into more wifi chipsets than just
Intel's, mediatek mt76, qualcomm ath9k and ath10k chips.

PS The only way I can think of to express how wireless signals degrade
over distance while using jugglers is via CGI, making the balls
diffuse and shrinking... Other ideas for how to express the inverse
square law simply, welcomed!

PPS (I'm quite curious as to how good the vanguard talk looked over
the much lower frame rate zoom participants, and how much freezing or
distortion of the feed they had)

Nope. "A" for concept, and "A" for performance.

I teach juggling (semi-professionally - I'm TheJugglerMan.com) and this was a first-rate show. All the more impressive since the three jugglers probably only had a short time to internalize your script and rehearse the tricks.

I especially liked how the initial club exchanges made them look like inexperienced jugglers - using two hands to throw and catch. Followed by the real surprise when suddenly there were all those clubs flying, passed by the three people :-)

Thank you for your continuing effort to popularize explanations of how the internet *really* works.

I cavort on the shoulders of giants!

I'm going to give myself an "A" for concept, but a "B" for performance. The latter half could have gone a bit faster, and one of the more difficult tricks, where one person already juggling tosses a ball (new flow) to another to incorporate it into their flows, was too hard to do, and didn't come off. Bunch of other flaws - notably I'd to say over and over again it would be better to think about an optimum for a low latency metaverse-capable internet would be for everyone to think more about "steady kilobits per millisecond".

It's very hard to express how fair queuing works, also, correctly, in the context of this talk. There are quite a few other networking concepts that I hope could be explained in this way, the difficulties with doing full duplex wireless using a water ballon to splatter the reciever was originally part of the act but I cut it in deference to the hotel staff!

> Dave, you should consider stand-up... :-)))

I've been thinking about retiring, and opening up a comedy club in Starbase, Texas, with a marachi band on sundays.

After working on theory, code, standards, and serious publications for so long, and being trapped behind zoom for the past 3 years, I needed an live outlet, like this, to stretch out a bit. I miss the high speed interactions you get out of "improv" for example, that's not a zoom-able thing. After the conference Bruce invited me to a musical jam which was *awesome* and also an example of what cannot presently be done well over the present day internet. One day, I hope.

It was so great to get out and do this, and perhaps I'll do it again one day or film it more carefully and not live.

If y'all would like a mostly serious explanation of many of the problems wifi has (With a fun explanation towards the end of what all OSes had been getting most wrong about wifi until then), please see the 8 minute segment here:
https://www.youtube.com/watch?v=Rb-UnHDw02o&t=1550s or, preferably, pass the whole thing to someone making wifi chips and drivers.

The related paper is rather dry in comparison, unless you get excited about 10x reductions of network latency across the board in cdf plots.
https://www.usenix.org/conference/atc17/technical-sessions/presentation/hoilan-jorgesen
- a huge (and still flailing) goal for me has been to get the now standard linux APIs for that into more wifi chipsets than just Intel's, mediatek mt76, qualcomm ath9k and ath10k chips.

PS The only way I can think of to express how wireless signals degrade over distance while using jugglers is via CGI, making the balls diffuse and shrinking... Other ideas for how to express the inverse square law simply, welcomed!

PPS (I'm quite curious as to how good the vanguard talk looked over the much lower frame rate zoom participants, and how much freezing or distortion of the feed they had)
