White Rabbit¶
White Rabbit provides sub-nanosecond accuracy and picoseconds precision of synchronization for large distributed systems. It also allows for deterministic and reliable data delivery.
White Rabbit allows you to precision time-tag measured data and lets you trigger data taking in large installations while at the same time using the same network to transmit data.
- sub-nanosecond synchronization
- connecting thousands of nodes
- typical distances of 10 km between nodes
- Ethernet-based gigabit rate reliable data transfer
- fully open hardware, firmware and software
- multi-vendor commercially produced hardware
