4.3.13 PTP
The Precision Time Protocol (PTP) is a protocol used to synchronize clocks throughout a computer network. On a local area
network, it achieves clock accuracy in the sub-microsecond range, making it suitable for measurement and control systems.
PTP was originally defined in the IEEE 1588-2002 standard, officially entitled "Standard for a Precision Clock Synchronization
Protocol for Networked Measurement and Control Systems" and published in 2002. In 2008 a revised standard, IEEE 588-2008
was released. This new version, also known as PTP Version 2, improves accuracy, precision and robustness but is not
backwards compatible with the original 2002 version.
"IEEE 1588 is designed to fill a niche not well served by either of the two dominant protocols, NTP and GPS. IEEE 1588 is
designed for local systems requiring accuracies beyond those attainable using NTP. It is also designed for applications that
cannot bear the cost of a GPS receiver at each node, or for which GPS signals are inaccessible”
