VIAVI XhaulAdvisor real-time fronthaul analyser

VIAVI has expanded its NITRO Wireless portfolio with the addition of XhaulAdvisor, a scalable software solution offering real-time data for fronthaul verification, analysis, emulation and channel utilisation. Featuring real-time analytics, it enables Open RAN vendors, operators and OTIC labs to accelerate interoperability testing and end-to-end testing and troubleshooting.

Unlike conventional tools that require lengthy waiting periods for capture, post-processing and visualisation, the product enables a realistic testing and validation environment in real time. Vendors and operators rapidly correlate test anomalies to network events and troubleshoot fronthaul and transport timing, packet flows and channel utilisation, as well as analyse M-plane, S-plane and C/U-plane sessions.

Various operation modes are available to fit different application needs, from set-up in passive or through mode to analysis in live or post-capture environments. Synchronisation can be achieved from open fronthaul or an external timing source.

Providing operational flexibility, the product can be deployed on commercial off-the-shelf hardware. It can also be integrated with other VIAVI tools already present in the testbed — such as TM500 and TeraVM — to speed up troubleshooting and root cause analysis, as well as flagging and isolation of issues caused by RAN, transport or synchronisation functions.
