Hi Karima, For iperf 2 <https://sourceforge.net/projects/iperf2/>use the -e option. This assumes the clocks on the client and server are synchronized to a level of the precision one cares about. We use a GPS disciplined oven controlled oscillator in our labs for a high quality reference then use precision time protocol to distributes that clock.
o) Support end/end latency in mean/min/max/stdev format (UDP) (-e required) (assumes client and server clocks synched, e.g by Precision Time Protocol to an OCXO oscillator per Spectracom) There is also support for full histograms vs mean/min/max/standard deviation. o) Latency histograms for both packets and frames (e.g. --udp-histogram=10u,200000, 0.03, 99.97) More on enhanced features here <https://sourceforge.net/projects/iperf2/files/Iperf%202.0.13a%20Enhancements.pdf/download> . Also, suggested use the latest 2.013a from sourceforge. We're very close to releasing 2.0.13 Bob On Wed, Jan 16, 2019 at 3:11 AM karima smida <karima.sm...@gmail.com> wrote: > Hi all, > please how to calculate End to End delay from informations returned by > iperf? > In fact, I want to use iperf to inject UDP traffic in may SDN network to > test its performance in terms of delay and overhead. > Thank you for help. > > -- > > _______________________________________________ > Iperf-users mailing list > Iperf-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/iperf-users >
