Detecting Network Asymmetries

When properly configured, TimeKeeper is able to detect and measure a network route asymmetry.

To setup a network to test for an asymmetry:

  1. Setup a TimeKeeper instance on a system configured to be a PTP or NTP client to a local VelaSync server/Grandmaster (via LAN). This will be Source (0).
  2. At the other end of the network route that you wish to measure, you must have another PTP or NTP server with a GPS reference.

To enable measuring a network route for asymmetry:

  • Navigate to Configuration > TimeKeeper Configuration > Sources, and check the box Detect asymmetry for the NTP or PTP sources you want to measure.
