GREAT to hear from you sean! (I added you as "accept" to the bloat list, but did not subscribe you. You can subscribe if you want to stay on) I am delighted to see all the places pion is popping up now, most recently I hear it is in matrix´s stacked SFU implementation? That is a very interesting case of multiple control loops, that makes my head hurt.
We have very few tests for videoconferencing performance in the world today. I have no idea how good any of the ones I have heard of, are. Have you looked over what the FCC uses? Samknows? Cloudflare? Do you have one or more you like? This paper that just went by was quite pleasing: https://tma.ifip.org/2023/wp-content/uploads/sites/12/2023/06/tma2023-final37.pdf But I do not know enough about their method. I have been hoping, with the public testbeds the libreqos project runs, and/or with the co-operation of one or more of the ISPs that use it, to somehow be able to accurately test & simulate the behaviors of videoconferencing traffic, but someone with funding, interest and time, has not shown up yet. (we know it is superlative, as most calls about videoconferencing problems just vanish on deployment of libreqos) We are able now (via ebpf) to gather and analyze all sorts of stats at scale, and substitute different qdiscs like fifo or pie, than the ones (fq_codel, cake) we use in production. We do not have a good wifi or lte emulation however. So you are welcome to attempt to leverage our testbed for your analyses or setup your own. The source code for libreqos is on github. The main server has a demo here: https://payne.taht.net - click "bandwidth test", drill down - but is only testing greedy and voip-like traffic in the test suite, presently. I am passionately interested in further understanding how well google congestion control is working in the field today, as well as in other videoconferencing methods.
