High Accuracy Timing for Managed Service Providers

Problem We Solve

Improve monitoring capability, including accuracy and precision within their infrastructures and democratize high resolution time-based services to their client communities.

Why it is Important

Better accuracy and precision between trading sites
Automatic failover between GNSSGlobal navigation satellite system (GNSS): A general term describing any satellite constellation that provides positioning, navigation, and timing (PNT) services on a global or regional basis. See also sources at geographically diverse sites
Simplification of existing PTPPrecision Time Protocol is a protocol used to synchronize clocks throughout a computer network. On a LAN network, PTP can enable the clocks on each server to be synchronized within a sub-microsecond range, thus making it suitable for demanding applications that require precise timing and control. PTP is standardized within IEEE-1588v2. network designs with improved accuracy
Improved accuracy and precision for timestamping cards or switches
Removal of requirement for PPS coaxial cabling within timing infrastructure
Reduction in overall timing infrastructure

How We Solve it

The WR-Z16 is a standalone device with 16 SFP connectors which provides sub-nanosecond accuracy time over plug-and-play optical fiber links. The WR-Z16 provides very precise IEEE 1588-2008 (PTP) in all its optical interfaces and supports NTPNTP, or Network Time Protocol, is a widely used networking protocol that enables computers and devices to synchronize their system clocks with a reference time source. It ensures accurate timekeeping in computer networks by allowing devices to obtain precise time information from NTP servers, which are typically synchronized to highly accurate atomic clocks. NTP is essential for various applications and services that rely on synchronized time, such as network security, authentication, and data logging. interoperability. Picosecond-level frequency distribution is available through a fully digital clock. The WR-Z16 incorporates failover mechanisms which combine multi-source redundancy and holdover capabilities to ensure continuous operation.

White Rabbit provides sub-nanosecond level accuracy for all time stamped traffic passing
through the infrastructure. This increases monitoring capability, improves historical data capture and introduces the possibility of additional client facing services related to timing.

Subsequently, enabling offerings of high precision timestamp file based services and White Rabbit co-location access to trading participants.
