Operations in Critical Infrastructures rely more and more on assured and accurate time distribution. Precise time-stamping of high frequency events or transactions is a key enabler for monitoring, security and performance measurement of all kind of transaction-based operations. Time and Frequency synchronization quality has a direct impact on reliability and performances of multiple civilian and governmental communication systems.
As a way to meet the demand for quick infrastructure growth, including efficiency and scalability improvement, network-based time distribution is seeing strong adoption across all infrastructure industries. Interoperability requirements have led to the standardization of different network-time protocols, enabling time-transfer accuracy improvement from milli-second level (NTP), to sub-micro-second (PTP, IEEE1588). They also lead to supporting higher speed network interfaces, with the on-going migration from 1Gb Ethernet to 10 Gb Ethernet, or faster, interfaces.
