What is PTP?

Next-gen network timing

Network Time Protocol (NTP), the long-established standard internet protocol for synchronizing computer clocks in data networks, is insufficient for a growing number of applications. It can’t provide the high levels of timing accuracy that sectors like financial trading, national power grids and defense increasingly rely on. And, as CSPs roll out higher-speed LTE-A and 5G services, packet networks must evolve to satisfy ever more stringent time and phase sync regulations. By incorporating Precision Time Protocol (PTP) into their networks, operators can pave the way for ultra-precise phase and time synchronization.

Nanosecond precision

Migrating to PTP is key to 5G network synchronization.
Our suite of PTP grandmasters is optimized for deployment from the core of the network to the edge.

Synchronizing finance

Meeting the latest regulatory requirements for timing accuracy in trading networks requires the transition from NTP to PTP.

How does PTP differ from NTP?

In contrast to NTP, which is frequently implemented in software, PTP prefers hardware-processing of timestamps for higher accuracy. As network devices process timestamps and compensate for intrinsic delay, PTP delivers synchronization with higher levels of accuracy over time-aware packet networks. A rich set of performance monitoring functions makes PTP the preferred timing technology for mission-critical applications.

Full range of deployment scenarios

Our synchronization devices deliver PTP timing with unprecedented accuracy and full quality control using our unique Syncjack™ service assurance capabilities.

Sync-aware, everywhere

Our Oscilloquartz suite of timing solutions is optimized for deployment from the core of the network to the edge. Our core PTP grandmasters all feature a modular design that scales for future requirements. Mid-sized PTP grandmasters offer agility and power combined with a small form factor. Highly portable and edge-optimized GNSS PTP grandmasters deliver powerful sync capability right where it’s needed. And our ultra-compact SFP pluggable PTP grandmasters provide an inexpensive way to optimize legacy equipment for contemporary synchronization requirements. All PTP grandmasters also provide NTP server capabilities for a smooth migration from legacy NTP towards highly accurate PTP architectures.
