I am also surprised. However, we have had a total of 5 complaints about
network speed over a 3 year period.
One possible reason is that because they own the infrastructure collectively
and pay for the bandwidth directly (I just manage everything for them), they
are prepared to put up with
Paul,
I have hard time seeing how you aren't maxing out that circuit. We see
about 2.3 mbps average per customer at peak with a primarily residential
user base. That would about 575 mbps average at peak for 250 users on our
network so how do we use 575 but you say your users don't even top 100

And what happens when a significant fraction of those users fire up Netflix with
an HD stream?
We're
A 100/100 enterprise connection can easily support hundreds of desktop users if
not more. It’s a lot of bandwidth even today.

Mixed residential (ages 25 - 75, 1 - 6 people per unit), group who worked
together to keep costs down. Works well for them. Friday nights we get to
about 85% utilization (Netflix), other than that, usually sits between 25 - 45%

If they’re residential and use OTT data then sure. If it’s SMB you’re likely
in better shape.

Certainly.
Projecting demand is one thing. Figuring out what to buy for your backbone,
edge (uplink & peer), and colo (for CDN caches too!), for which
scale+growth is quite another.
And yeah, Jim, overall, things have stayed the same. There are just the
nuances added with caches, gaming, OTT

Louie,
Its almost like us old guys knew something, and did know everything back
then, the more things have changed the more that they have stayed the same

Do these “quic and tcp bbr” change bandwidth utilization as we’ve know it for
years ?

We use trendline/95% trendline that’s built into a lot of graphing tools…
solarwinds, I think even cdn cache portals have trendlines… forecasts, etc.
My boss might use other growth percentages gleaned from previous years… but
yeah, like another person mentioned, the more history you have the
pretty good judgements
on future needs. Less data and/or not very far back
lessens the accuracy of a prediction about the future.

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
