[LibreQoS] SCALE 21x conference this week results?

[-- Attachment #1: Type: text/plain, Size: 2833 bytes --]

I am curious if anyone here is at scale this week? (it is in pasadena, and
one of my favorite conferences - https://www.socallinuxexpo.org/scale/21x )
One of our core bufferbloat contributors (david lang) used to fq_codel the
wifi there and they built custom boxes to manage the wifi in general
(leveraging openwrt), I am not sure how they are doing it this year.

I always appreciate random users testing with speedtest,
cloudflare,flent,irtt on the conference wifi, and would love results from
this one especially. David published an update to this document a few years
ago, but I cannot find it. This was the state of play in 2013.

It was the best wifi on the planet then.

we are having some issues with ipv6, since you are a big ipv6 advocate, you may 
be able to help

we get IPv6 via a hurricane electric tunnel and apparently PMTU discovery is 
misbehving. We've tried reducing the MTU a bit but still having issues.

If MTU discovery fails it's usually because a device is trying to
seamlessly fragment.  Set do not fragment on your device nearest the
customer and that should solve it.

Re: [LibreQoS] [Make-wifi-fast] SCALE 21x conference this week results?

[Dave Taht]

I do not have a good answer anymore. My guess is blocking ipv6 tcp
port 443 and leaving udp port 443 open would work due to quic choosing
a lower packet size in general, and thus no pmtu needed.
