White Rabbit

This document (preliminary version) describes the functional requirements that the White Rabbit Switch must accomplish.

Description of White Rabbit protocol which extends IEEE1588-2008 standard.

Attached is a movie from Tomek's demo of White Rabbit during presentation at CERN.

Demo highlights that synchronization in WR is completely plug&play.

The movie is available with a bit better quality here: http://www.youtube.com/watch?v=ZZsEr0TTTEk...

Attached is a movie from Tomek's demo of White Rabbit during presentation at CERN.

Demo demonstrates delay tracking in variable conditions.

M.Sc thesis describing the exact synchronization algorithm used in WR and the WR Switch.

This documents puts together some preliminary thoughts about White Rabbit's application to control and provide timing for accelerators at CERN (replacing General Machine Timing).

Posters in conferences, workshops and other meetings.

Presentation and demo done in the context of the CERN Fieldbus Working Group on Thursday 26 January 2012.

Informative contribution prepared for ITU-T Q13/Q15 meeting in Boulder

White Rabbit logo in different formats (including vector graphic) can be found here.

The "*-original" files contain the logo which was drawn by hand and scanned (authored by Alexandra Lewis).
The "*-vectorized" files contain the logo which was re-drawn from the original in Corel Draw to provide useful vector graphic (accepted by the original author).
