AT&T's policy for measured burstable service looks something like this:
The Provider Access Router is polled every 5 minutes for total octets in and
total
octets out.
Data is divided by 300 (the number of seconds in a 5 minute period),
giving two averages (one in, one out) for the previous 5 minute period
These averages become data points, which are tracked over the course of
the customer's monthly billing cycle. Top 5% of the data points are
disregarded (be they IN
or OUT).
We bill at the 95% level of usage
