White-Rabbit -> White Rabbit projects
Sub-projects
WR technology
- White Rabbit Standardization - it covers all efforts geared to standardize White Rabbit, with a view to providing a stable specification which everyone can use to build compliant products.
- PPSi - A Precise Time Protocol (PTP, IEEE 1588) software stack whose single source code can be compiled for many architectures (POSIX systems, SPEC...). It will be used both on switches and nodes.
- White Rabbit Network Robustness - a broad subject covering methods (HW & SW) which enable to increase overall reliability of a WR-based system.

White Rabbit basic systems
- White Rabbit Network Interface Card - a White Rabbit compliant Network Interface Card (NIC) based on the SPEC and the DIO FMC.
- White Rabbit Starting Kit - this project demonstrates the functionality of a basic timing system in order to get people started on White Rabbit (WR).
- Compact Universal Timing Endpoint based on White Rabbit - a compact WR node implementation with minimum components required.
- Distributed Direct Digital Synthesis over White Rabbit - D3S
Switch-related
- White Rabbit Switch Hardware - this project covers the hardware development of the White Rabbit switch.
- White Rabbit Switch HDL - this project contains all the HDL necessary for the FPGA of the WR switch.
- White Rabbit Switch Software - software for the WR switch, and in particular the embedded Linux system running in the ARM9 processor.
- White Rabbit Switch Testing - a project to host all software and hardware developments related to testing the WR switch.
Related projects

Pending Projects (needing help)
We often have more ideas than manpower. Whether you are a student looking for an interesting (and useful!) BSc/MSc/PhD project, or if you are an open-source-oriented company looking for a new contract (we may actually pay you), you can possibly find something interesting. The list includes pure ideas as well as proof-of-concept implementations that need to make it into the release of the White Rabbit switch, with a major clean-up or rewrite.
