White-Rabbit -> Detailed information
Description
White Rabbit (WR) is a solution to the generic problem of transferring
data in a fast, deterministic and safe manner. Although its initial
scope is mainly targeted at timing systems for experimental physics
facilities, care has been taken to come up with a solution which is as
generic as possible. The aim is to be able to synchronize ~1000 nodes
with sub-ns accuracy over fiber and copper lengths of up to 10 km. The
main technologies used are physical layer syntonization (clock recovery)
and PTP (IEEE 1588). Compliance with established standards such as
Ethernet and PTP is a key goal of the project.
This OHR project is both the home of the hardware design for the White
Rabbit switch (fully open hardware licensed under the CERN Open
Hardware Licence) and an
umbrella for general WR-related documents and discussion. In particular,
the publications page contains key working documents
such as the White Rabbit specification as well as publications,
presentations and other useful material. Several potential
users have expressed interest in WR, and some commercial
companies are collaborating in design tasks and will
commercialize the results.
The WR switch software is dealt with in a separate subproject.
Seven Solutions, one of the commercial companies involved, has prepared a nice web page about WR and other associated developments.
