Bandwidth Measurement

Filed under: Geek — jbm @ 7:42 pm

I just learned about 95th percentile bandwidth measurement. Since I’m not hidden behind your typical ISP or telco service any more, I’m going to start seeing some of the real effects of providing bandwidth, and what it takes to make it economically feasible. Old hat for ISPs, I know, but I’ve paid flat rate ISP fees for so long, I’ve never seen anything else. MRTG is making this very nice to keep an eye on.

  1. Jim,
    Question about 95th percentile: Why is “95″ the magic number? Why not “93″ or “87″ or whatever? I’ll assume there’s some theoretical type of math behind this (that I probably won’t understand) or is this based upon empirical observations?
    thanks,
    Julie

  2. Hi Julie! I have no idea where the number came from. I suspect it’s more empirical than theoretical, and related to whether a given ISP is able to become profitable, but I’ll go ask someone who might know. -Jim
