delay calculation

[Nicolas S. <nic...@wa...>]

Hello,

I'm new in networking and iperf usage. And I need a little bit help.
For a script project  I must get this values from site A to site B :
Jitter delay, %loss pkts, and delay (not simple RTT)
I get easyly the 2 first parameters, but one thing : iperf gives jitter 
delay but not the delay (time to go from A to B)
Is there a way to calculate this ? A simple "ping" is not enough as the 
A <--> B line is asymetric so with a ping the time to A --> B isnt the 
same as B--> A .
Thanks for any help and sorry asking newbie questions.
