Hi,
Sorry this is not a specific ns post, but if someone knows:)
In the RFC 1889 the instantaneous jitter is given by:
J=J+(|(Rj-Sj)-(Ri-Si)|-J)/16
I'm running a simulator and i have the packets sent and received
time. The problem is that i don't know how iperf gives the final
result, so i can't do the same and compare the real results with the
simulator results.
while iterating, if i do:
Jsum=J+Jsum, and then J_average=Jsum/(num_packets-1) the results
wouldn't be the same as iperf because in a extract:
[EMAIL PROTECTED]:~$ iperf -c 192.168.101.11 -u -b 500k -t 30
[ 3] 0.0-10.0 sec 479 KBytes 393 Kbits/sec 9.184 ms 0/ 334 (0%)
[ 3] 10.0-20.0 sec 471 KBytes 386 Kbits/sec 11.203 ms 83/ 411 (20%)
[ 3] 20.0-30.0 sec 468 KBytes 383 Kbits/sec 10.314 ms 99/ 425 (23%)
[ 3] 0.0-32.5 sec 1.50 MBytes 388 Kbits/sec 11.123 ms 205/ 1277 (16%)
the value 11.123 ms is not the average of the another 3 above.
