Thanks Bob

These are directional one way delays. They're shown on the client for convenience (vs requiring one to look at the server for OWD-TX and the client of OWD-RX.) The RTT equivalent is the BB8 PDF.
-
Thanks for the clarification. So am i correct to think that OWD-TX-PDF is effectively a PDF of RTT - but perhaps without the return trip? Could I make use of OWD-RX-PDF to factor in the return trip?
-
See the man page. PDF are histograms with binning. OWD is for one way delay ng.

I am trying to get something like a histogram of TCP RTT and I've been poking around at various things. Could someone point me to a description of OWD-TX-PDF and OWD-RX-PDF please, I cant seem to find a reference to what it is a PDF of exactly. Also I see in the above, --bounceback-period 0, - what does this do?

Oh, I can check this in the server header output. Server listening on UDP port 5001 with pid 43577 Read buffer size: 1.44 KByte (Dist bin width= 183 Byte) Enabled receive histograms bin-width=0.100 ms, bins=10000 (clients should use --trip-times) UDP buffer size: 208 KByte (default)

Thanks for your reply.
