Constructing a sub-nanosecond time synchronization network using White Rabbit: Proof-of-concept study on a distributed White Rabbit Switch

Highly accurate time sources, such as Cesium-based or GPS clocks, are the best candidates to provide a correct notion of time, but are too costly and impractical for implementation in every modern digital device. Ubiquitously, (crystal) oscillators are employed instead. To maintain a shared notion of time, the offsets and drift/jitter have to be...
