White-Rabbit -> Switch
The White Rabbit Switch (WRS) is the key component of the White Rabbit
System that provides precision timing and high accuracy synchronization
in an Ethernet-based network.
The WRS-3/18 version is a standalone version with 18 SFP connectors. The
WRS distributes the clock of a WRS master (or its internal clock) to all
the nodes in the network using a hierarchical architecture.
