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