modeling residential subscriber bandwidth demand

Residential whatnow?

Sorry, to be honest, there really isn’t any.   

I suppose if one is buying lit services, this is important to model.  

But an *incredibly* huge residential network can be served by a single basic 10/40g backbone connection or two. And if you own the glass it’s trivial to spin up very many of those.   Aggregate in metro cores, put the Netflix OC there, done.

Then again, we don’t even do DNS anymore, we’re <1ms from Cloudflare, so in 2019 why bother?

I don’t miss the days of ISDN backhaul, but those days are long gone. And I won’t go back.
