abstract = {Highly accurate synchronization has become a major requirement because of the rise of
distributed applications, regulatory requests and position, navigation and timing backup needs. This fact
has led to the development of new technologies which fulfill the new requirements in terms of accuracy
and dependability. Nevertheless, some of these novel proposals have lacked determinism, robustness,
interoperability, deployability, scalability or management tools preventing them to be extensively used in real
industrial scenarios. Different segments require accurate timing information over a large number of nodes.
Due to the high availability and low price of global satellite-based time references, many critical distributed
facilities depend on them. However, the vulnerability to jamming or spoofing represents a well-known
threat and back-up systems need to be deployed to mitigate it. The recently approved draft standard IEEE
1588-2019 includes the High Accuracy Default Precision Time Protocol Profile which is intensively based on
the White Rabbit protocol. White Rabbit is an extension of current IEEE 1588-2008 network synchronization
protocol for sub-nanosecond synchronization. This approach has been validated and intensively used
during the last years. This paper revises the pre-standard protocol to expose the challenges that the High
Accuracy profile will find after its release and covers existing applications, promising deployments and
the technological roadmap, providing hints and an overview of features to be studied. The authors review
different issues that have prevented the industrial adoption of White Rabbit in the past and introduce the
latest developments that will facilitate the next IEEE 1588 High Accuracy extensive adoption.},
