Yeah you're probably right.
I was given results from a survey done by the school district where
there are people in the middle of a mid-sized city reporting that they
have "no service available" or "insufficient speed". I felt like some
of those "insufficient speed" people really have a tech support
issue.....or maybe their kid is lying to them like you're saying.
The "no service available" I figured just can't afford it. Or else they
really want their kid to go to actual school.

To get OT and maybe Lenty: I hope CPS is going to cut some slack about
unattended minors this year. If you're telling parents the kid has to
stay home, but mom and dad still have to work, and by the way daycare is
closed too, then you're just going to have some kids home alone. It
didn't kill us in the 80's, so I think it'll be fine anyway, but people
get a bug in their bonnet about that these days.

In theory the upstream bandwidth could be a problem, because Zoom
says they need a little over 1 Mbps both directions.
What I’ve actually seen is adults working from home typically have
a steady 1M symmetric during a video conference. School kids on
the other hand are all over the map. The traffic isn’t constant,
and the upstream seems a lot less. I think it may depend on how
they have it set up, like do you see the whole class in
thumbnails. And the upstream may only go to a big number when the
teacher calls on that student?
One thing’s for sure, you get a house with WiFi coverage issues
and a whole bunch of Zoomers, and they’re going to be calling and
bugging the crap out of us. It’s similar to gamers who call
saying things like it’s freezing or lagging or there’s audio but
no video or one kid is fine but the other can’t get on. And it’s
an existential crisis that has to be fixed right now this
nanosecond and you hear the kids yelling at the mom in the
background. Some problems are people on the lowest speed plan
with insufficient upstream, but others I’m not sure what their
problem is. One is saying only one of their kids can Zoom but
their neighbor on our service and the same speed plan has 4
Zooming no problem. Does that mean they go to the same school,
are in the same grade, have the same teacher? Probably not. And
could it be WiFi issues? Probably.

we have one house with 5 remote learners, other than when theres a
file getting uploaded, even on a small connection the mother ive
been communicating with has said its been working flawlessly. is
zoom related to skype in its back end?

Porn isn't zoom.....at least not yet. Maybe that's the next
new normal.
Netflix also isn't zoom.
So if 5 kids using Zoom on a 3mbps connection is the problem
then what you say is true. If it's 1 or 2 kids competing with
other households' Netflix and Chill then QoS can address that.

I have observed that Zoom seems to use a little bit of TCP
presumably a control channel and mostly UDP I think it’s
on something like port 8801. Not sure if you have 3 or 4
students in the same house and maybe 1 or 2 adults all
Zooming, if additional ports get used, kind of like VoIP
using 5060, 5061, 5062, etc.

Apparently they already set DSCP values to 56 for the
audio and 40 for the video.
Trusting DSCP from the Internet carries other dangers
though (like Apple thinks iPhone software updates need
expedited forwarding).

unless maybe find the absolute minimum requirements

Is the a simple way to classify Zoom traffic for

a layer7 match or matching a certain IP block.
School is restarting soon (online) and I'm
