Indeed, Jason. Bufferbloat is still here and most of the people outside of our little bubble even doesn't know the word itself.

My anecdotal evidence says that many people working in Wi-Fi, WLAN or similar field still never heard even the term bufferbloat:

Been to https://www.thewlpc.com/conferences/prague-czech-republic-2023 this week, there was ~200 guys that install, manage or survey Wi-Fi networks on stadiums, hotels, campuses, universities and other venues, and there was NO mention of bufferbloat at all, and the mentions of the words like latency and jitter could be counted on 2 hands.

I have tried to ask about it every vendor there (e.g. Ruckus, Extreme Networks...) and their product or engineering guys said they never heard of it. Some of the guys in the attendance suggested that "it's just the ISP thing, you know, for the ISP customers at home." Sad story.

All the best,

Frank

Upstream usage in the US in 2020 increased 30% - 60% (https://www.bitag.org/documents/bitag_report.pdf). Then it reverted to a normal CAGR.

Also here are two charts of LUL changes across much of the US since 2021 FWIW (don’t have data before that, this is from the SamKnows system – which is pretty good). I don’t know how else to conclude that while there have been improvements, buffer bloat is still pretty atrocious on a national level.
