I ran an iperf session on a Windows NT machine (server) from a Sun machine(client) that generated the report below. I must misunderstand the process of calculating jitter because I don't understand why the final jitter is not the same as the average of the sum of the individual report intervals.
Are the individual lines worst-case and the final number an average?
The average I get by taking sum (jitter*packets) per line/ total packets = ~4.07.
Thanks for any help in understanding
