Excerpts from Chao-Fang Shih's message of Tue Mar 29 11:46:34 -0500 2011:
> Hi all,

> I would like to know how iperf measure the jitter?
> Is it the average value of the difference of consecutive delay in 1 second?
> Or is it the standard deviation of the delay in 1 second?
> Please tell me the exact way how iperf measure the jitter or give me some
> hint to find it out.
> Thank you very much.
