Following on from the previous article, I’ve written some scripts which you’ll find in the /root/scripts/ directory of the prebuilt image. I’ve attached and commented them here, as they could also be useful elsewhere.

95th percentile billing commonly misspelled as “percential” is a method used by some NOCs to change for bandwidth.
The system is simple and essentially discards the top 5% of your traffic peaks, and then uses the next value down as your bandwidth rate. 5% of a month is 36 hours. This might sound like a bit of a scam, because you’re being billed for bandwidth consumption that you may not have used, but it’s not difficult to get it to work for you.
If you’re hosting a site where a lot of content is downloaded, it may be better to go for bandwidth billing. A client’s content server uses about 8,000GB transfer per month and shows a 95th percentile of 34mbit/sec. It’s certainly cheaper to pay for 8,000GB transfer over 30+mbit/sec dedicated.
