From what I see, throwing more bandwidth doesn't really change the
video streaming. So that makes sense what the FTTH Guys say. Streams
happily sit around 5-7mb/stream regardless of the available bandwidth.
I've been testing this out, running multiple video streams, between 4k
and 1080 TV's, hardwired and WIFI. I can barely get my total connection
to top 20mb/s sustained only by having 3 streams running at once.
For VOD Shows, I see a spike in Bandwidth at the beginning of a show, up
to the connection max (Downloading what appears to be a specific size
buffer, the faster it runs the shorter the burst), but then it settles
down during the show. For Live Viewing, it's just constant 5-7mb.
File Downloading/game updates are a different story, they will take all
available bandwidth, but only until the download is finished. The faster
the speed, the shorter it takes.

Maybe the trend is accurate, but I don’t think you can do network
planning based on GB/mo because what matters is peak traffic levels.
It used to be peak traffic was Monday morning when everyone got to
work and opened their email. Now it’s 8-9pm when everyone is
streaming video.
The other factor is video streams (and to a certain extent software
downloads) use more bandwidth if you have a faster connection. People
are not cranking up the video quality dial from 480 to 720 to 1080 to
2160, they may not even appreciate the extra pixels they are seeing.
It just happens automagically because their connection allows it.
Perhaps this doesn’t matter because monthly data usage and peak
bandwidth are correlated. Same reason mobile network operators charge
by gigabytes per month, it’s easier to track and the people who use
the most data probably are the heaviest users at peak times. Kind of
unfair to people who game, watch TV, or download software in the
middle of the night. But that’s why the satellite Internet guys give
you “bonus bytes” in the middle of the night.
I am still amazed that the FTTH providers here report customers use
about the same data usage per customer as we see on our bandwidth
constrained WISP network. If I could give every customer gigabit or
even 100 Mbps, a lot of their video streams would automagically jump
to 20 Mbps as their kids watch My Little Pony in 4K UHD on their
iPads. Of course everyone in the house has their own video stream
going on their own device. No more whole family sitting in front of
the living room TV watching the same show. Even the kids have their
own iPad and watch different cartoons.

Here's a study from Cisco forecasting 26% worldwide compound annual
growth in IP traffic through 2022, and 21% for North America:

I'm currently seeing 3mbps on average per FTTH household at peak
traffic time. Chuck was saying 4 earlier....so we're in the same
ballpark. Allow at least a gig of overhead so your gig customer can
get a gig when he actually wants/needs it.
We've been around 25% or so CAGR on bandwidth for a long time, but it
varies on individual years from 15% to 100%. I think it was a year in
the early 2010's where we had the 100%.

Mark, I'm working on a grant application and they are wanting to
see proof (and a PE stamp) on the design that it will meet
performance requirements for X years. I'm very comfortable with
GPON at a 32 split or less being fine for probably at least 8+
years. Just was asking if there is an industry standard way of
calculating this or if everyone doesn't worry about it. I suppose
it would be much more relevant if we were proposing a VDSL system
instead of FTTH.

Chris,
Does it really matter? If you are AE you get 1GB per customer
dedicated. Not too hard or expensive to to bump that to 10GB
per customer dedicated. GPON does 2.5Gbps per pon usually
shared by 32 customers. New 10 Gbps PON will do 10 per pon or
I've even heard that they can do 40Gbps per pon using
different wave lengths.
Our system has been up and running for 6+ years. I've had to
upgrade switches and routers. Even had to upgrade to sfp+
uplink cards on one of my fiber systems. Haven't had to touch
GPON cards or customer ONT's. In my system I see the 2.5Gbps
PON lasting for many many years unless something drastic happens.

Is there any standard or common rule of thumb to design for
future usage when designing a FTTH deployment? As in, we
estimate average usage per sub to be 2Mbps now and increase by
40% per year. The intent being to certify that your design
will meet demand for say 10 years.
