WR @ ISPCS2012
ISPCS2012 conference is the PTP conference. Since WR extends PTP, it is very important for the project.
At the conference, WR was very visible thanks to as many as 3 WR-related papers which were presented and our participation in the PlugFest.

3-10-2012: White Rabbit studies for Spanish accelerator
After an extensive study, White Rabbit has been chosen as the most
promising option for the synchronization network at ESS
Bilbao, a light ion linear
accelerator. Therefore, first
SPEC to SPEC tests have been
performed.
Now, with a White Rabbit
switch a new
set up will be tested to provide synchronization signals for ESS
Bilbao’s hydrogen positive ion source (ISHP) in the near future. For
2013 ESS Bilbao is planning to test PXI SPECs
(SPEXI) which is the most
suitable platform for the integration of White Rabbit into ESS Bilbao’s
general control system.

2-10-12: White Rabbit in Tibet?
LHAASO, the Large High Altitude Air Shower Observation project will be
deploying 10,000 detectors over 1 square km in Tibet.
The LHAASO project has passed the technical review on the WR timing
distribution plan
that consists of 4 layers of WR switches (461 in total) covering the
6880 nodes of the Square Kilometer Array (KM2A). It would be able to
provide both a timing link and synchronous data acquisition network to
every detector front-end for a trigger-less scheme.
For 2013 it is planned to deploy a small portion of array (40-50 nodes)
in Tibet using cute-wr, an
FMC mezzanine card that carries a White Rabbit receiver.

White Rabbit presented in CERN's fieldbus WG
WR was successfully presented in CERN’s fieldbus working group. You can find the slides and some pictures, including the latest and greatest 18-port switch box at https://www.ohwr.org/project/white-rabbit/wikis/Documents/White-Rabbit-as-a-fieldbus-(presentation)

Basic Ethernet switching demonstrated
The WR v2 switch demonstrated real-life Ethernet packet switching in the last WR developer meeting by transferring a big video file between two laptops.

WR switch PTP compliance tested in ISPCS 2010 plugfest
Tomasz went to ISPCS 2010 and tried the prototype WR switch with other PTP-compliant devices during the plugfest. The switch successfully talked PTP with hardware from Hirschmann, Beckhoff, Oregano, Ruggedcom, Semtech and ZHAW.

First two-month development cycle for WR switch started
The WR switch design effort is transitioning into a new development model, with two-month cycles that include a kick-off meeting for planning the two months of work and a meeting at the end to check results. The project is now split into HW (lead by Tomasz Wlostowski) and SW (lead by Alessandro Rubini) development. A separate sub-project has been created for the SW part. The goals for this first two-month effort can be seen in the wiki pages of both projects.
