data transport over neutrinos would help! seriously, iw10 and cubic knock utp out of the way to a larger extent that is a start. I would like it if we saw more work in the area of making ledbat lighter in the light of deployment of fq and aqm technologies. > Simon > > Sent with AquaMail for Android > http://www.aqua-mail.com > > On May 18, 2015 8:09:39 AM dpr...@reed.com wrote: >> >> I'm curious as to why one would need low priority class if you were using >> fq_codel?
