...definately one of those things that need to be asked about during contract negotiations... -----Original Message----- From: Alex Rubenstein [mailto:alex () corp nac net] Sent: April 19, 2001 10:09 AM To: 'nanog () merit edu' Subject: What does 95th %tile mean? I've gotten myself into an argument with a provider about the definition of 'industry-standard 95th percentile method.' To me, this means the following: a) take the number of bytes xfered over a 5 minute period, and determine rate for both the inbound and outbound. Store this in your favorite data-store. b) at billing time, presumably on the first of the month or some other monthly increment, take all the samples, sort them from greatest to least, hacking off the top 5% of samples. Actually, this is done twice, once for inbound, once for outbound. Then, take the higher of those two, and multiply it by your favorite $ multiple (ie, $500 per megabit per second, or $1 per kilobit per second, etc). I think that most people agree with the above; the issue we are running into is one rogue provider who is billing this at in + out, not the greater of in or out. How is everyone else doing it? Specifically, larger folks (UU, Sprint, CW, Exodus/FGC, GX, Qwest, L3) Thanks!
