List Of PTP Implementations
Precision Time Protocol (PTP) is a widely adopted protocol for delivery of precise time over a computer network. A complete PTP system includes PTP functionality in network equipment and hosts. PTP may be implemented in hardware, software or a combination of both. PTP is implemented in end systems and in PTP-aware networking hardware. PTP implementations may have the ability to serve as a source of time for the network, a ''grandmaster'', or operate as a ''slave'' and receive time and synchronize to the grandmaster. Some implementations are able to operate as either master or slave.

Precision Time Protocol
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 is employed to synchronize financial transactions, mobile phone tower transmissions, sub-sea acoustic arrays, and networks that require precise timing but lack access to satellite navigation signals. The first version of PTP, IEEE 1588-2002, was published in 2002. IEEE 1588-2008, also known as PTP Version 2 is not backward compatible with the 2002 version. IEEE 1588-2019 was published in November 2019 and includes backward-compatible improvements to the 2008 publication. IEEE 1588-2008 includes a ''profile'' concept defining PTP operating parameters and options. Several profiles have been defined for applications including telecommunications, electric power distribution and audiovisual. is an adaptation of PTP for use with Audio Vid ...

PTPd
PTPd is an open source implementation of the Precision Time Protocol for Unix-like computers. Derivatives * ''PTPd'' is a complete, BSD licensed, open source code implementation of the IEEE 1588-2008 PTP specification. Currently only Unix-like computers can run the software, but this essentially means that FreeBSD, Linux, Mac OSX, Minix3 and QNX computers can participate in PTP networks. PTPd can act as a master on a system with an external time source, such as a GPS card, or NTP running as a client. * ''ptpd2'' was intended to be a complete open source implementation of the IEEE 1588-2008 (PTPv2) PTP specification. The project was abandoned in March 2011. * ''ptpv2d'' is GPL re-licensed open source code of IEEE 1588 version 1, version 2 and IEEE 802.1AS including hardware timestamping for Freescale MPC831x family of processors. Accuracy PTPd accuracy depends on how IEEE 1588 packets are timestamped on the participating machines. When IEEE 1588 packets are timestamped in software, ...
