Tee-hee, flow queuing is like having a 1024 lanes that can be used for everything from pedestrians, to bicycles, to trucks and trains. I would settle for FQ everywhere over AQM. This has been a very fun conversation and I am struggling to keep up. I have sometimes thought that LiFi (https://lifi.co/) would suddenly come out of the woodwork, and we would be networking over that through the household. > > Bob > > Hi Bob, > > > > I like your design sketch and the ideas behind it. > > > > > >> On Mar 15, 2023, at 18:32, rjmcmahon via Bloat > >> <bloat@lists.bufferbloat.net> wrote: > >> > >> The 6G is a contiguous 1200MhZ.
