[AusNOG] the state of bufferbloat awareness and remediation in australia?

Hi, all. I'm here at linux.conf.au having just given a talk about how
tcp works in the bufferbloated age[1].

On my way here I stopped in for a few days with geoff huston and
george michaelson who filled my ears with the chaos of the NBN rollout
and other issues in the australian network infrastructure... and gave
me a shot at some data they had on bloat, and ecn usage in the wild
which I hope to write up over the next month or so.

I was wondering about a few things:

How y'all doing on eliminating bufferbloat from your networks? Using
things like fq_codel, sch_fq + bbr, etc?

Do you have any awareness from your regulatorium?

I see, from sites like whirlpool, that some consumer hardware here,
like the fritzbox, have fq_codel now, but it's not clear if ISPs are
actively configuring it (or what we call "sqm") yet. (theres a PPPoe
message now in use in parts of germany for up/down and frame rate
seeing increasing deployment).


Anyone need a wayward network researcher/theorist for a few weeks or
months to help address their bufferbloat issues in their stacks and
hw? - maybe not this trip but on some other occasion?
(I rather like hanging in australia)
