1588: Definition and Recommended Links

The Precision Time Protocol (PTP) is a time-transfer protocol defined in the IEEE 1588 – 2002 standard that allows precise synchronization of networks (e.g., Ethernet). Accuracy within the nanosecond range can be achieved with this protocol when using hardware generated timestamps, although the protocol itself has no quality requirement. The Institute of Embedded Systems (InES) of the University of Winterthur is addressing the practical implementation and application of PTP.

IEEE 1588 is a key technology in the LXI Standard for Test and Measurement communication and control.

'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 very high 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.'

      PTPd

      The PTP daemon (PTPd) implements the Precision Time protocol (PTP) as defined by the IEEE 1588 standard. PTP was developed to provide very precise time coordination of LAN connected computers. PTPd is a complete implementation of the IEEE 1588 specification for a standard (non-boundary) clock. PTPd has been tested with and is known to work properly with other IEEE 1588 implementations. The source code for PTPd is freely available under a...

      Special Focus: Understanding the IEEE 1588 Precision Time Protocol

      Measurement and automation applications often must precisely synchronize events over a widely distributed system. For example, an industrial automation system may need to synchronize distributed motion controllers, or a test and measurement system may need to measure strain gages distributed over the wing span of an airplane. The IEEE 1588 precision time protocol (PTP) provides a standard method to synchronize devices on a network with...

      IEEE 1588 - Precise Time Synchronization as the Basis for Real Time Applications in Automation

      More and more data can be transferred and processed in shorter and shorter time. This trend is observed in automation technology. Because of this, Ethernet has been chosen as the transport technology for the foreseeable future. Beside speed of transmission and ease of setup, the words “real time” have a special meaning in this field. A substantial facet is precise time synchronization of different end devices. With the Precision Time...

      Introduction to Distributed Clock Synchronization and the IEEE 1588 Precision Time Protocol

      Measurement and automation systems involving multiple devices often require accurate timing in order to facilitate event synchronization and data correlation. For example, an industrial automation application may need to synchronize distributed motion controllers, or a test and measurement application may need to correlate data acquired from sensors distributed across a device under test. To achieve this synchronization, devices in the...

      IEEE 1588 Unplugged - An introduction to IEEE 1588

      IEEE 1588 provides fault tolerant synchronization for different clocks along the same network. There is very little bandwidth consumption, processing power, and setup. IEEE 1588 accomplishes all of this by using the precision time protocol, or PTP. The time protocol synchronizes all clocks within a network by adjusting clocks to the highest quality clock. IEEE 1588 defines value ranges for the standard set of clock characteristics. The Best...
