I rather enjoyed doing this podcast a few weeks ago, (and enjoy this podcast a lot, generally), and it talks to what I've been up to for the past year or so on fixing bufferbloat for ISPs.

Thank you for the link! I'll give it a listen this evening.
Pathetically, what did you think?
I am kind of curious as to how much XDP and EBPF now exist in the nanog universe and other applications y'all are finding for it?
We at Cloudflare use both XDP and eBPF extensively for our load balancing and DoS mitigation applications: https://www.google.com/search?q=site%3Ablog.cloudflare.com+xdp+OR+ebpf
David Tubes (of cloudflare) gave a pretty good talk at our recently concluded "understanding latency conference. Toke gave a pretty good talk on the state of bpf Kathie Nichols talked about some nifty packet analysis techniques Vodaphone opened with surprising candor about there being no demand for > 1gbit Nokia talked about L4S Stuart Cheshire of apple talked about their RPM metric Had a good panel with ookla And me, I channeled Roy Beatty from Blade Runner for all the network problems I have seen and attempted to fix in just the past few weeks, for a 3 minute monologue. https://www.youtube.com/watch?v=tAVwmUG21OY&t=6483s :) I would really like to start a "back to packet captures" movement! Have MS-clippy show up and say "Your network is being weird, would you like me to take a packet capture?", and/or daveGPT3 chime in. Anyway, last blatant plug on this list, if you want to feel some mild winds of positive change, please cue up: https://www.understandinglatency.com/recordings-2023 and pass around.
