If everything is Zoom, and you prioritize Zoom, you prioritize everything. It’s like everyone is a winner, but if nobody loses, what’s the point?
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 <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. School is restarting soon (online) and I'm thinking this might be a hot item. -Adam -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
