To: Dave Taht via Bloat Just a quick shoutout to Will Hawkins goresponsiveness effort (h++ps://github.com/network-quality/goresponsiveness: open source go implementation along the lines of the RPM IETF responsiveness draft (h++ps://github.com/network-quality/draft-ietf-ippm-responsiveness). The goal I think is a quick latency under working conditions/latency under load for the rest of us. I think the draft likely will get a last call soon, so whoever wants to add something to the spec or just wants to comment, now would be a good time: goresponsiveness is currently acquiring a few nice features, like the ability to compare the latency between idle and working conditions, run both saturating loads concurrently, and to report the sub results for the "self" probes (measuring latency within the load generating connection/flow) and the "foreign" probes (measuring latency outside of the load generating flows) bash-3.2$ ./networkQuality --relative-rpm --rpm.parallel --config mensura.cdn-apple.com --port 443 --path /api/v1/gm/config --rpm.timeout 120 --extended-stats --rpm.mnp 32 --logger-filename go_networkQuality_20231228_223707 --detailed 01-08-2024 19:37:07 UTC Go Responsiveness to mensura.cdn-apple.com:443...

Please ignore the download direction, this is over a 100 Mbps USB ethernet dongle and my true download shaper is set to 105 Mbps, so this is mostly the bad USB dongle in action... _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat --=20 40 years of net history, a couple songs: https://www.youtube.com/watch?v=3DD9RGX6QFm5E Dave T=C3=A4ht CSO, LibreQos
