just a few comments:
slide 17: it is not fully clear that this is about downstream only, especially "sch_cake can (with perfect framing) be at the same setpoint as the upstream, while still taking back control of the link, with better queuing." is confusing me. 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%).
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...

>>> 3) Megabits per second myth
>>> #3 is the accurate one, but in this day and age every syllable can somehow slow an idea down. I’m leaning towards #2. I’ve also heard non-technical people say “how many Megabits is it?” when referring to an Internet connection, as if the “per second” part is already too much to handle. :)
