If you want to run some experiments, though, you could look at running
PTPd
on 3 servers (master, and two slaves) which will get you decent
synchronization
among the three. Where decent is less than the typical RTT of a TCP
packet on a
1Gbps LAN.

Yes, you are correct, I meant to write "relative OWD". As David Hayes
put
it - "Relative OWD measurements are easier, and clock drift is not

a problem over the time it takes to send and receive an ACK".
Thank you for the correction!

I have yet to solve the issue of
how to get the One Way Delay for the ACK message (the time it takes
ACK

arrive from receiver of the ACK'ed data sender) correctly.
That won't work without synchronized clocks, which you can't really
assume
to be present.
