The revision process of the IEEE1588 Precision Time Protocol (PTP)
|
|
|
|
standard started in mid-2013. The revision work is done by the [P1588
|
|
|
|
Working Group](https://ieee-sa.centraldesktop.com/1588public/), which
|
|
|
|
consists of over 180 members from all over the world representing
|
|
|
|
industry and science, including CERN.
|
|
|
|
The Working Group is arranged in 5 sub-committees focusing on different
|
|
|
|
aspects of the PTP revision, namely: Architecture, Management, Upkeep,
|
|
|
|
Security and High Accuracy Enhancements. The High Accuracy sub-committee
|
|
|
|
is lead by CERN representative. It is dedicated to evaluating White
|
|
|
|
Rabbit solutions and generalizing them to a broader range of
|
|
|
|
applications.
