Let’s not forget that the kids or others in the home might have been doing large downloads at the same time trying to have these calls. Some of these game updates are massive and if they are running at the same time performance will surely suffer. Since the kids are home all day it is much more likely that this would happen now.

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.

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.

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. From: AF <mailto:af-boun...@af.afmug.com> <af-boun...@af.afmug.com> On Behalf Of Adam Moffett Sent: Wednesday, September 2, 2020 12:25 PM To: af@af.afmug.com Subject: Re: [AFMUG] Zoom QoS 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).

Like a layer7 match or matching a certain IP block.
