This article provides a non-exhaustive overview of applications and
enhancements to the White Rabbit (WR) extension of the Precision Time Protocol (PTP).
enhancements to the White Rabbit (WR) extension of the IEEE1588 Precision Time Protocol (PTP).
Initially developed to serve accelerators at the European Organization for
Nuclear Research (CERN), WR has become widely-used synchronization solution
Nuclear Research (CERN), WR has become a widely-used synchronization solution
in scientific installations. This article classifies WR applications
into five types, briefly explains each and describes its example
installations. The article then summarizes WR enhancements that have been triggered by
different applications and outlines WR's integration into the PTP standard.
Based on the presented variety of WR applications and enhancements, it concludes
that WR will continue to proliferate in scientific applications and should soon find its way into the industry.

\section{Conclusions}
\label{sec:conclusions}
WR is an innovative solution to provide sub-ns accuracy and picoseconds
precision of synchronization over large distances.
The number of WR applications and their specifications have exceeded the original
assumptions of the project.
This proliferation can be attributed to the fact that WR is based
on standards and it is openly as well as commercially available while meeting
very stringent synchronization requirements. The open nature of WR allows its users to contribute to the
expectations of the project.
This proliferation can be attributed to the fact that WR is standard, open and
commercially available. The open nature of WR allows its users to contribute to the
project with their
specific expertise and new developments, opening WR to more applications.
WR has become a \textit{de facto} for synchronization in scientific installations
and it is now becoming an industry standard within the IEEE1588.
With its wide adaptation in science, commercial support, up-coming
standardization and EU-funded project to catalyze applications in the
industry, WR applications will continue to proliferate in
science and should soon find its way into industry.
