- **Towards distributed fault-tolerant timekeeping based on a
|
|
|
WR-network**: This talk will review progress and plans towards
|
|
|
distributed fault-tolerant timekeeping based on a White Rabbit
|
|
|
network of clocks. Open hardware is being developed for high
|
|
|
performance clock distribution, multiplexing, measurement, and
|
|
|
steering. Software for distributed and fault-tolerant modeling of
|
|
|
clocks is being developed based on a Kalman filter approach.

- **White Rabbit Industrial Timing Enhancement**: Time signal
|
|
|
distribution is important both in scientific and industrial fields.
|
|
|
There is an increasing demand for synchronization networks that
|
|
|
provide precise time and frequency from telecommunication operators
|
|
|
building 5G mobile communication networks, the power-grid sector
|
|
|
that builds and utilizes smart grids and other sustainable energy
|
|
|
solutions, the financial sector to comply with EU regulations, and
|
|
|
scientific users. New techniques for Time and Frequency
|
|
|
dissemination on optic fiber today offer the best performance and
|
|
|
the highest resilience. White Rabbit Precision Time Protocol
|
|
|
(PTP-WR) is one of the most performing time transfer techniques,
|
|
|
providing sub-nanosecond accuracy, resilient and secure timing
|
|
|
traceable to Coordinated Universal Time (UTC). It has been
|
|
|
demonstrated that WR-PTP can be successfully implemented in
|
|
|
long-distance optical fiber links. Since June 2018, a consortium
|
|
|
composed of 10 institutions, NMIs, companies and academia,
|
|
|
coordinated by INRIM within the program EMPIR of Euramet, is taking
|
|
|
part in the project "WRITE"http://empir.npl.co.uk/write/ (White
|
|
|
Rabbit Industrial Timing Enhancement). During the White Rabbit
|
|
|
workshop, I will present the new features that will be developed to
|
|
|
improve the WR-PTP capabilities and to facilitate the take up at the
|
|
|
industrial level. These include: calibration techniques to obtain
|
|
|
reliable, accurate traceability; devices to improve the robustness
|
|
|
and resilience of PTP-WR. Moreover, some tests involving industrial
|
|
|
users are planned.
