Precise Time Synchronization for Industrial Time-sensitive Networks (TSN)

Beschreibung

Time synchronization is one of the main pillars for the next generation of Ethernet-based Industrial communication systems. Control loops, synchronized sampling and scheduled communication required time synchronization with at least 1 microsecond accuracy.For TSN networks, IEEE Std. 802.1AS-2020 is defined for this purpose. It is also known as gPTP – generalized Precision Time Protocol. This project will research the impact of the defined mechanisms for certain application cases, particularly for network infrastructure devices.

Support for up to four time synchronization domains in parallel
Support for pre-engineered networks with up to 100 devices in a line configuration
Backward compatibility with legacy devices

The project is a cooperation with Belden-Hirschmann, a supplier of Industrial Ethernet Equipment. Corrections and improvements for the standard will be fed back to IEEE.
