perfSONAR User Q&A and Other Discussion

[Chris Knudsen <>]

I have done this on PI2s, each with it’s own adafruit GPS hat and configured as a stratum 1 NTP server, so each has sub msec accuracy.  My use case is testing and development of control applications that are latency sensitive over distributed wireless networks.  It is fairly straight forward to set up and it works great.  I did need to use the PI2s as the PI3s changed the way the UART clock works such that it is not stable and therefore the serial GPS connection does not work properly.

We started to experiment with using R Pi's using OWAMP to collect measurements for jitter, delay, and packet loss.  Our goal was to collect metrics to better understand what the networks effects were when we were using Audio over IP for different locations.  The R Pi is capable of doing these measurements, granted we installed hardware Real Time clocks on the R Pi and synced them to each locally GPS referenced NTP servers at individual locations.  It was something we were trying to get working, but got temporarily shelved for a different project.  But it is something we would like to do again.

I realize that underpowered ARM-based platforms aren't support, but I wonder if anyone has experience running OWAMP on a Raspberry Pi 3 or similar.


if so, can you share some details such as OS, clock source, experience, etc.

thanks,
