+1.
So my question is, how do you handle the translation from 95th% to throughput billing?
With considerable difficulty. Take a simple 1mbit throughput figure: theoretically, if you were transferring data at a continuous 1mbit/sec, you'd be looking at a throughput of around 315GB/month. But traffic rarely works like that. If it's a business customer, their traffic is likely to be in the ~8am-6pm range. A domestic customer is likely to be ~4pm-2am. A hosting customer will vary wildly depending on the profile of their site visitors.
Our "best guess" approach is to assume that most usage will be over an 8 hour period, so we work on 1mbit/sec = 100GB/month, give or take. Occasionally we get it wrong, but there's enough of a safety margin to offset that.
If there's a magic formula, I'd love to hear about it. Kind regards, Chris -- C.M. Bagnall, Director, Minotaur IT Limited For full contact details please visit www.minotaur.it This email is made from 100% recycled electrons
