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.
The White Rabbit project is an on-going collaborative project for which first generation components are being designed and evaluated for use in real, mostly scientific, applications (June 2012).
The hardware design for the White Rabbit switch is licensed under the CERN Open Hardware Licence) while the firmware and driver software also is available under "open" licences.
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.
