The Precision Time Protocol (PTP) is a protocol for clock synchronization throughout a computer network with relatively high precision and therefore potentially high accuracy. In a local area network (LAN), accuracy can be sub-microsecond – making it suitable for measurement and control systems. [ 1 ]
The PTP Industrial Profile (PIP) is a standard of the IEC 62439-3 [1] that specifies in its Annex C two Precision Time Protocol IEEE 1588 / IEC 61588 profiles, L3E2E and L2P2P, to synchronize network clocks with an accuracy of 1 μs and provide fault-tolerance against clock failures.
syn1588 PTP Stack from Oregano Systems: A portable implementation of the complete IEEE1588-2008 standard with special features like Boundary Clock support, Unicast operation, IPv6 support and security enhancements. [93] The Linux PTP Project – an implementation of the Precision Time Protocol (PTP) according to IEEE standard 1588 for Linux ...
IEC/IEEE 61850-9-3 is a profile (subset) of IEEE Std 1588 Precision Time Protocol (PTP) when clocks are singly attached. IEC/IEEE 61850-9-3 provides seamless fault tolerance by attaching clocks to duplicated networks paths and by support of simultaneously active redundant master clocks. For this case, the extensions to PTP defined in IEC 62439 ...

Picture Transfer Protocol (PTP) is a protocol originally developed by the Photographic and Imaging Manufacturers Association (PIMA) (later known as the International Imaging Industry Association) to allow the transfer of images from digital cameras to computers and other peripheral devices without the need for additional device drivers.
To achieve sub-nanosecond synchronization White Rabbit utilizes Synchronous Ethernet (SyncE) to achieve syntonization [5] and IEEE 1588 (1588) Precision Time Protocol (PTP) to communicate time and a module for precise phase difference measurement between the master reference clock and the local clock based on phase frequency detectors.
The standard was developed by the Audio Engineering Society and first published in September 2013. It is a layer 3 protocol suite based on existing standards and is designed to allow interoperability between various IP-based audio networking systems such as RAVENNA , Wheatnet , Livewire , Q-LAN and Dante .
