Hi,

I?ve recently taken a trace from two machines running Microsoft Netmeeting,
and was checking for Jitter and Delay.  The sniffer trace worked perfectly,
but the figures are some what shocking, jitter has a mean of 10ms and the
Delta varies between 30 -60ms.  However this is all fine, but when I run
the same trace using Network observer or clear sight the values of jitter
are 8 times greater at 80ms and well above desired levels.  If the capture
from Ethereal is exported to Network observer the values are that of 80 ms
jitter.  Anyone seen this before and can explain why this is the case?  Really
confusing, need to get the same values from both?

Thanks

Mark
