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

[Rick Bollar]

   Hi Richard,

   NTPViz can generate those reports and more. It works with NTPSec and
   NTP and (Chrony with a

   conversion script).

     I have a question about using NTP servers to measure network
     performance. I have a MPLS Wide Area Network with GPS locked NTP
     servers at each location. 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:
     40th Annual Precise and Time Interval (PTTI) Meeting
     Studying Network Timing With Precision Packet Delay Measurements
     https://apps.dtic.mil/sti/pdfs/ADA503429.pdf
     Can anyone recommend a low cost or freeware way to measure packet
     delay and packet jitter using NTP associations or IEEE-1588? Don't
     care if it is Linux or Windows OS.
     Thanks,
     Richard
