In the RFC 1889 the delay jitter is given by
J=J+(|(Rj-Sj)-(Ri-Si)|-J)/16
I use iperf to measure delay jitters between two network nodes. I got
[ 3] 0.0- 1.0 sec 18.7 KBytes 153 Kbits/sec 8.848 ms 0/ 13 (0%)
[ 3] 1.0- 2.0 sec 15.8 KBytes 129 Kbits/sec 8.736 ms 0/ 11 (0%)
[ 3] 2.0- 3.0 sec 15.8 KBytes 129 Kbits/sec 17.437 ms 0/ 11 (0%)
[ 3] 3.0- 4.0 sec 15.8 KBytes 129 Kbits/sec 15.929 ms 0/ 11 (0%)
[ 3] 4.0- 5.0 sec 12.9 KBytes 106 Kbits/sec 11.942 ms 0/ 9 (0%)
[ 3] 0.0- 5.0 sec 80.4 KBytes 131 Kbits/sec 18.451 ms 0/ 56 (0%)
I want to know jitters every second and do statistics but I found I can't calculate the average jitter at the end of the iperf report. What's the relationship of jitter between the average and every-second record.
