[Bloat] can we setup a "how to get this into existing networks" get-together in Prague coming week?

Btw, I reached out to some people here at the BBF about doing 
anti-bufferbloat in this context and getting this into the documents, and 
there is no reason why this can't be introduced.

Now, the proposal needs to be "reasonable" and implementable, so if 
someone would be interested in work like that I'd like to hear from you. I 
have taken initiative in trying to come up with configuration guidance for 
operators for their existing equipment, and that could be a way forward.

So this won't be "put CAKE or FQ_CODEL everywhere", but instead introduce 
configuration guidance regarding bufferbloat, best common practice for 
different deployment scenarios etc. Let's not try to boil the ocean right 
away, but let's try to point industry in the right direction. BBF creates 
documents that architects networks that connects ~1B households, so 
whatever we come up with could benefit lots of people.

I understand that for some people here this will seem like stone age 
primive mechanisms, but it's still better than doing nothing at all (which 
is often the case). It would especially be beneficial to get similar 
guidance from several organisations (CableLabs and BBF would be two that 
immediately comes to mind).

I'll be at the IETF meeting monday-friday coming week, can we set up a 
meeting with some interested parties and actually have a "how do we get 
this into networks" kind of meeting. It would not be "my mechanism is 
better than yours" meeting, I'm not interested in that in this context.

I'm interested in "what can we do to improve the situation in the next 1-2 
years including installed base".
