I wish vumatel the best of luck. One thing that still will help the
fiber networks is applying fq_* derived algoritms.

This is cake vs sonic (gpon) fiber in san francisco. They have a
totally reasonable (60ms) buffer in their ONT, cut to... well... the
result I get is even less latency loaded than unloaded:


In my mind fq techniques merely on the up on fiber onts will make a
huge difference in perceived QoE, and the marketing department can
keep claiming it's fiber bandwidth that counts to consumers.

FIOS uses actiontec. I haven't picked apart what kernels the use in a
couple years.


(hey verizon FIOS? gfiber? you listening?)
