abstract = {Time synchronization faces an increasing performance
demand nowadays. This is particularly common
in different segments, such as new scientific infrastructures,
power grid, telecommunications or fifth-generation
(5G) wireless networks. All of them share the need for a time
synchronization technology offering a very low synchronization
error along large networks. The new version of the
IEEE-1588-2019 protocol offers a considerable performance
improvement thanks to the high accuracy profile based on
white rabbit (WR). The original WR implementation guarantees
a synchronization accuracy below 1 ns for a small
number of cascaded nodes. This contribution evaluates the
performance degradation when a considerable number of
devices are deployed in cascaded configurations. In order
to improve the performance, different delay measurement
implementations have been evaluated in a series of experiments.
The results prove the considerable benefits of our
implementation against the current WR implementation.},
