Re: modeling residential subscriber bandwidth demand

["Robert M. Enger" <nanog () enger us>]

An article was published recently that discusses the possible impact of Cloud-based gaming on last-mile capacity 
requirements, as well as external connections. The author suggests that decentralized video services won't be the only 
big user of last-mile capacity.

Subject: modeling residential subscriber bandwidth demand 

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?
