ADVA has released new software that extends its Oscilloquartz timing assurance technology to synchronization networks using Network Time Protocol (NTP).

ADVA’s Ensemble Sync Director management system provides assurance control, helping mission-critical services across many industries that depend on reliable and accurate NTP timing.

The new NTP capabilities are extended from ADVA’s robust Oscilloquartz Precision Time Protocol (PTP) product range and supported by Syncjack GNSS monitoring. They also leverage multiple form factors with redundant synchronization devices, multiple holdover options and versatile multi-technology gateways between GNSS, PTP and NTP, ensuring robust, scalable and highly resilient NTP timing architectures.

“Despite the availability of PTP, NTP remains the most widely used time synchronization protocol,” said Gil Biran, GM of Oscilloquartz, ADVA. “It’s applied in many legacy networks as well as new IoT (internet of things) applications. What’s more, the sophistication of NTP timing is increasing, while the NTP protocol itself remains unchanged. Now we’re enabling our customer to deploy robust, reliable and secure NTP implementations built on our unique expertise and experience in delivering assured synchronization.”

ADVA uses a combination of NTP architecture and highly accurate GNSS timing backed up with PTP timing domains.

Because ADVA’s products now support assured NTP technology, they offer customers virtually unlimited scale, Biran said. “With hardware-implemented NTP functionality, even the smallest SFP (small-form factor pluggable) NTP server can support up to 500,000 transactions per second.”

To ensure NTP delivery is able to withstand a broad range of risk scenarios, ADVA’s resilient synchronization solution is engineered for both device and network redundancy. It features multiple backup options such as PTP- and GNSS-delivered time, as well as a variety of oscillator solutions that allow different levels of holdover.

Comprehensive monitoring by ADVA’s Ensemble Sync Director management system helps guarantee the levels of performance required for time-critical network applications. Designed from the bottom up to support continuous assessment and assured timing precision, it automatically responds to any issues before applications can be disturbed by timing inaccuracies.

ADVA’s solutions also offer centralized GNSS monitoring and assurance, protecting timing networks from vulnerabilities, including jamming and spoofing attacks.

Customers can build NTP-based networks today and switch to PTP with one click, commented Nir Laufer, vice president of product line management at Oscilloquartz, ADVA. “Our customers no longer need to hope for the best from their NTP servers,” Laufer said. “With real-time GNSS monitoring and comprehensive probing and analysis of timing quality, they can rest assured that their synchronization services have the highest levels of accuracy, integrity, availability and scale.”
