Isn't the setpoint for each direction = determined by the available bandwidth, so having up and downstream at = the same setpoint requires a symmetrical link (aka an unicorn link in = the context of residential uplinks). Or are you talking about the same = _percentage_ of the setpoint (which with cake's ingress mode should both = be close to 100%). =20 slide 24: you might as well add Deutsche Telekom and it is Vodafone not = Vodaphone, there see sa comma missing after Zyxel (it might make sense = to move Zyxel to the other OEMs ODMs instead of into the ISPs). Also lowet might be "lowest"? slide 28 the GPON timeslice is 0.25 ms, it would be super intersting to = look at the actual packet arrival/departure times of the latency probes, = obviously not by 9 AM ;) slide 29: not clear what this refers to, the last plot shoed total = goodput, which should not care about the number of measurement flows = (unless you mean more latency probe packets as these will "eat" into the = bandwidth available for data packets) in other words I am confuzed ;) slide 30: it would be nicer if the left and right plots would use the = same axis segments... > On Jun 26, 2018, at 08:58, Dave Taht wrote: >=20 > I got about, I don't know, 5? problematic slides, and it needs to get > to 20 by 9AM EDT, it's 3AM and I'm gonna catch some zs. >=20 > http://www.taht.net/~d/cake/sch_cake_ieee_lanman2018.odp >=20 > On Fri, Jun 22, 2018 at 10:14 PM, Dave Taht = wrote: >> I have to get on the plane tomorrow night at midnight and I've tried >> to capture some of your comments and ideas in: >>=20 >> http://www.taht.net/~d/cake/sch_cake_ieee_lanman2018.odp >>=20 >> It's in its usual mess at this point - usually I don't share stuff >> this raw! but I'm totally open to text suggestions, graphics, etc, >> etc, etc - there's the plane flight and more than a few days left to >> pound it into shape and after I get a feel for the conference monday >> will end up doing another pass before the talk tuesday.
