X-BeenThere: make-wifi-fast@lists.bufferbloat.net X-Mailman-Version: 2.1.20 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 25 Jan 2020 15:42:07 -0000 What I had pushed for in multiple private meetings with multiple providers was for wifi 6 to expose a per station API to the host AP cpu. This neatly rids the host AP of as much need to grok MU ( I really like the potential in MU) or per station tx rates while still giving the smarter AP CPU the ability to schedule stations, FQ packets and manage bufferbloat. A per station API makes gang-scheduling more feasible in MU-MIMO. There were many other suggestions made along the way (privately) like having a transmit or receive is almost done interrupt, "prepare!", and I hope some of those ideas were adopted. I'd hoped of course to attract some actual paid work on wifi 6, but so far have only a teeny grant to look over the intel ax200 mess.

I think the implementations of thes= e is outside the standard as well. Those writing traffic schedulers will m= ostly likely be impacted. > > Bob > > On Fri, Jan 24, 2020 at 6:06 AM Rich Brown wrot= e: >> >> I saw this overview of the now-in-testing Wi-Fi 6 at https://www.howtoge= ek.com/368332/wi-fi-6-what%E2%80%99s-different-and-why-it-matters/ >> >> Its multiple MIMO streams and maybe talking to multiple devices at a tim= e seem as if they might be outside the assumptions we use. >> >> >> _______________________________________________ >> Make-wifi-fast mailing list >> Make-wifi-fast@lists.bufferbloat.net >> https://lists.bufferbloat.net/listinfo/make-wifi-fast > > > > > ---------- Forwarded message ---------- > From: Bob McMahon via Make-wifi-fast > To: Rich Brown > Cc: Make-Wifi-fast > Bcc: > Date: Fri, 24 Jan 2020 12:49:53 -0800 (PST) > Subject: Re: [Make-wifi-fast] Wi-Fi 6 - how many of our assumptions does = it violate? > _______________________________________________ > Make-wifi-fast mailing list > Make-wifi-fast@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/make-wifi-fast --=20 Make Music, Not War Dave T=C3=A4ht CTO, TekLibre, LLC http://www.teklibre.com Tel: 1-831-435-0729
