First PRP tester demonstrated
At the IEEE-1588 Plugfest during ISPCS 2025 in Ottawa, ALBEDO took part both as an Exhibitor and active participant, bringing together our Net.Time clocks and the new ZEUS tester, the WORLD first IEC-61850 PRP tester in the market. Our Net.Time clocks were successfully connected with other participants’ equipment, including IEDs, Clocks, and appliances, to validate PTP/NTP/IRIG-B interoperability under PRP networks compliant with IEC 61850-9-3.

Zeus a PRP enabler
The highlight was ZEUS, which enabled PRP redundancy validation, packet capture, and performance measurements in complex dual-LAN architectures (LAN A / LAN B). This milestone extends our testing capabilities into redundant Ethernet synchronization, a key fault tolerant technology for Utilities, Energy and other mission critical infrastructures.

ALBEDO at the Plugfest
In 2025 ALBEDO’s participation in the Plugfest was truly distinctive. While most companies bring only testers or clocks, ALBEDO contribute both:
- Zeus testers: to validate interoperability under realistic conditions
- Net.Time clocks: reliable synchronization in multi-vendor environments
This combination allows us to not only verify interoperability but also to actively measure, diagnose, and push PTP systems to their limits. We’ll test scenarios involving jitter, leap seconds, rogue masters, asymmetry, packet delay variation, and more. By doing so, ALBEDO contributes two perspectives at once: as a device under test (clocks) and as an independent observer and validator (testers). Very few companies in the industry can play this dual role.
What is ISPCS?
ISPCS is the world’s leading forum for precision clock synchronization in measurement, control, and communication systems. Each year, it brings together researchers, network operators, utilities, manufacturers, and industry leaders to exchange ideas and shape the future of IEEE-1588 and related technologies.
