White Rabbit - Ethernet-based solution for sub-ns synchronization and deterministic, reliable data delivery

Presented at NI by Maciej Lipinski

Electronics Engineer Fellow at CERN, Co-chair of the High Accuracy sub-committee in the P1588 Working Group


White Rabbit is a project that aims to create an Ethernet-based network with low-latency, highly reliable, deterministic data delivery and network-wide, transparent, high-accuracy timing distribution. The White Rabbit Network is based on existing standards (IEEE 802.1, 802.3, IEEE 1588) and enables sub-nanosecond synchronization of thousands of devices spanning over several kilometers. Conceived as a next-generation control and timing system for Particle Accelerators such as those at CERN, it is rapidly finding new scientific and commercial applications. An ongoing effort attempts to include a White Rabbit extension to IEEE1588 into the standard. This presentation provides an overview of the White Rabbit project, its current developments and an ever-growing list of applications. A light-weight insight into time and data distribution in the White Rabbit network, as well as standardization efforts and WR-based systems at CERN are presented.

I wonder how it is realted to NI , NO NI HW was showen .

Although this was meant to be mostly educational... PXIe and CompactRIO were mentioned as WR nodes. To learn how WR relates to NI read this article:

Are there any updates on NI-based WR support?  How does all this tie in with Time Sensitive Networking, I believe there is significant overlap.


Will NI be offering WR IP for FPGA cards in order to expand these horizons to general High-speed serial applications?
