Deutsche Börse deploys White Rabbit solution
Deutsche Börse, a German exchange deployed White Rabbit to improve accuracy and precision for internal timestamping via FPGAField-Programming Gate Array: an integrated circuit designed to be configured by a customer or a designer after manufacturing – hence the term field-programmable. See also based switches.
Timestamping was across all participant cross-connects in co-location, totalling 500+ ports, 60 devices and 4 data center modules. 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, Deutsche Börse offered high precision timestamp file based services and White Rabbit co-location access to their trading participants.
Why White Rabbit?
Designed to improve, augment or replace existing timing infrastructure, White Rabbit drives value to exchanges by providing:
- Increased accuracy and precision for internal timestamping using cards or switches
- Time synchronization resilience with 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.

- 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
- Removal of PPS coaxial cabling within timing infrastructure
- The infrastructure to generate revenue driven time-based services such as data capture files or timing feeds to market participants
