[time-nuts] Re: Using NTP Server Time To Measure WAN Performance

[Magnus Danielson]

Hi,

I know that GMV have done tests with RPi running chrony to do such tests 
and reported in various forums quite recently.

Not perticular advanced tests, but that was revealing enough. They did 
care to check and calibrate things thought.

They took some care to record data and present it, consider using the 
influxdb and grafana combo. I typically use a python script to parse 
whatever and post into influxdb.

Cheers,
Magnus

I need to measure the network packet delay as well as packet jitter.  Looking on the NIST website I found this document via a trail of external web links:
