>Question/Comment:
>I would like to understand how time differences between an iperf client
and server machines are accounted for in UDP throughput, delay, jitter etc
calculations.
>
>Does iperf require an external mechanism like NTP or GPS synchornization
to ensure that clocks on client and server are precisely synchronized.
>
>Is there a document/web page explaining the way information is exchanged
via UDP packets.
>
>Thanks in advance.
