<div dir="ltr">That would make sense, if congested obviously the max available = max used = customers*average, but if a network is not run congested then available != max used, or somewhere in between max available = %congestion x max used, or the ultimate question is, what level of congestion delivers what (acceptable) user experience. Adding in AGVC congestion as another congestion point (although that = the current, just different backhaul). Think that is what Skeeve was after. Rather than the simple answer of 2000 customers with 2Gbit transit = 300GB/mo average, or 1.2TB for 20%, 75GB for 80%<div>

<div dir="ltr">I recently did some maths to help a friend with capacity planning with an idea he had (wireless not fiber, but medium agnostic generally) and we spit out a few different figures in terms of expected GB usage per month, peak usage if we gave everyone more than enough (ie 100Mbit vs 50Mbit (wireless g vs n), max agvc (well more just backhaul from basestation to blah, max transit), and then the actual amount we'd sell which made business sense (ie profit).<div>
<br></div><div>Surprisingly there was not a whole lot of difference between them, burstability (ie 100mb 'NBN' vs 50) obviously impacted the peak the worst, but applying 95th to that brought it down to within 20-30% of the business sense figures. This was with about 500mbit internet (so give perhaps 10-15% internal traffic), and 1200 customers. I'd expect at gbit+ (and say 2k customers) that things would be settling down even further. Residential usage as well.</div>
<div><br></div><div>This method is something I've come up with from experience with dedicated servers VPS VPN and similar, so it might not be 100% applicable as what someone else may offer up, but I'd expect usage from 100/1000/10Gbit servers (ie high burst) to be a little more applicable than plain old DSL (low burst relatively speaking).</div>
