Re: 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.

How do people model and try to project residential subscriber bandwidth demands into the future? Do you base it 
primarily on historical data? Are there more sophisticated approaches that you use to figure out how much backbone 
bandwidth you need to build to keep your eyeballs happy? 

Netflow for historical data is great, but I guess what I am really asking is - how do you anticipate the load that 
your eyeballs are going to bring to your network, especially in the face of transport tweaks such as QUIC and TCP BBR?
