[AusNOG] Average Usage Per Service

[Joshua D'Alton]

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).

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.

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).

Might be a bit of a business 'secret', but maybe someone from iiNet/Node
would be friendly and look over your figures ;)
