NANOG=E2=80=99ers:
Steve McManus of Akamai and I have a few questions regarding how =
providers use time zones for billing, and how the 95th percentile (95/5) =
is calculated.
Many ISPs use UTC on logs and such for reasons which should be obvious. =
But do they use local time for billing? What if there are ports in =
multiple time zones? When calculating 95/5 for LACP groups, is the =
aggregate used or individual physical ports? Etc.
We have created a short form to collect some real-world data on this.
https://goo.gl/d1HRNb
We fully understand this is far from a statistically randomized =
double-blind survey, but it is what we could do in the few minutes of =
spare time we had.
The form is only 7 multiple-choice questions, with two optional =
=E2=80=9Ccomment=E2=80=9D sections and an optional contact info section. =
We would really appreciate if people would share data (anonymously!) on =
how they bill or get billed.
The form is designed to be used once per relationship. If you have two =
upstreams who use two different billing methods, we would greatly =
appreciate if you could fill in the form twice. It seemed easier to have =
you click 7 radio buttons twice than ask you to explain the different =
methods on one form.
Thank you for your time. Results will be aggregated and published at =
some later date to be determined. If you would like the results faster, =
be sure to leave your email address in the contact section.
