Xena Networks - XenaTimeSynch One-Way Latency (OWL) Tool
- 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
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.
One Way Latency Reveals Hidden Problems
One-way delay and delay variation (jitter) measurements are important parameters for testing the quality of sevice (QoS) of real-time applications such as VoIP, telepresence and transactional services. High-level precision is required for both wireline (Ethernet access) and wireless backhaul networks for 4G (WiMAX / LTE), and typical SLA specifications call for unidirectional jitter below 1-5ms and latency in the 3-10ms range.
Service providers often use one-way measurements to check their SLAs, since round trip delay metrics frequently fail to identify QoS issues in asymmetrical access networks where download speeds typically exceed upload. Since a round-trip delay measurement aggregates send and receive path delays, unidirectional issues can escape detection or exacerbate troubleshooting efforts. One-way measurements can quickly identify and quantify these issues if conducted with sufficient precision and accuracy.
XenaTimeSynch ensures the test modules can measure with micro-second precision. Both the ubiquitous Network Time Protocol (NTP) and the newer, more precise IEEE 1588 Precision Time Protocol (PTP) are supported and can be mixed as appropriate for the network.
More Product Information
XenaManager is used to configure and generate streams of Ethernet traffic between Xena test equipment and Devices Under Test (DUTs) at all speeds up to 800Gbps, and analyze the results. It can also be used to add various forms of impairment up to 100Gbps when using the Chimera network emulator.
The user-friendly interface makes XenaManager an effective tool for performing a wide range of core test scenarios for semiconductor & Network Equipment Manufacturers (NEMs), network service providers, and hyperscalers.

In Nordic mythology, Loki is the god of mischief. In the world of Ethernet testing, Z100 Loki is an important part of the Xena product line, which is Xena’s Ethernet Traffic Generation & Analysis (TGA) solution.
Z100 Loki supports testing of NRZ-based Ethernet at data rates of 10G / 25G / 40G / 50G / 100G.
In the Xena line we also have Z10 Odin (NRZ testing 10Mbps to 10G), Z400 Thor (NRZ testing 10 to 100G and PAM4 testing 50G to 400G), Z800 Freya (10G NRZ to 800G PAM4) and the Z1608 Edun (112G & 224G SerDes) which can generate up to 1.6Tbps.
Xena OpenAutomation (XOA) is an open-source test automation framework for use with all Xena solutions.
Fast, easy to use and extremely flexible, XOA features a Python API that runs on any OS. You can use XOA in whichever way suits your test needs.
There are three main options:
- Use XOA CLI or XOA Python API to add Xena test equipment to your existing test automation setup.
- Use XOA CLI or XOA Python API to add Xena testers and run Xena test suites via your existing test automation setup.
- Use XOA to automate all your Ethernet testing.
