XenaTimeSynch

XenaTimeSynch is a feature that enables multiple Xena testers to synchronize their local time to each other. This can be used for One-Way Latency (OWL) measurements between two test chassis, synchronized traffic start between multiple chassis and accurate timestamping of captured packets in exported PCAP files.

The timing network consisting of the Xena testers can be flexibly configured to support multiple scenarios. One tester may serve time to the other testers (and any other host on your network) using NTP or PTP. Alternatively, each tester can obtain its own time from an external NTP, PTP or GPS source.

XenaTimeSynch uses an advanced time synchronization solution called TimeKeeper from the company FSMLabs. TimeKeeper synchronizes the local time on each Xena test chassis and must therefore be installed as a separate service on each Xena chassis and is configured and monitored through the XenaManager. 

Top Features

  • Wire-speed traffic generation and analysis
  • High precision solution for chassis time synchronization
  • Used for OWL measurements, synchronized traffic start and timestamping
  • Can use any combination of NTP, PTP or RFC 868 TIME
  • Legacy Xena testers can be retro-fitted with XenaTimeSynch (GPS requires factory refit)
  • Compatible with Xena1564 (ITU-T Y.1564) test methodology
