I've only begun to research this subject again. Back in the good ole days (2002!) I worked on asterisk and had a ton of rtp tools. Today, all the rtp information is encrypted so you can't get at it easily unless you instrument your own serv= er. There's been some really good webrtc work I've begun to look over - everything from janus from meetecho, to jitsi, to BBB, to something juliusz just whipped up over the weekend. and I had at one point (2014?) worked on google congestion control for rmcat and kind of understood how both NADA and scream were supposed to work. > > The spec seems light on expected results for Wi-Fi cases. > > 3.2.4, bullet 1: "The end-to-end delay and packet loss ratio experienced = by each flow should be within an acceptable range for real-time multimedia = applications".

I vastly prefer ieee 802.11 specs to ietf's, and in part, why flent exists, was to actually be able to look hard at this kind of stuff. But the place for feedback is on the relevant ietf list, it's just that sometimes easier to get the attention of experts, here.... > > > > > _______________________________________________ > Make-wifi-fast mailing list > Make-wifi-fast@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/make-wifi-fast -- Make Music, Not War Dave T=C3=A4ht CTO, TekLibre, LLC http://www.teklibre.com Tel: 1-831-435-0729
