Time-Sensitive Networking (TSN) enhances Ethernet (specifically IEEE 802.1 and 802.3) and adds a variety of functions and capabilities. The goal is to make Ethernet more suitable for industrial applications requiring more deterministic characteristics than possible with present Ethernet standards.

The IPMS TSN Ethernet Subsystem is an IP core to ease integration of devices into networks complying with TSN standards. It provides time-sensitive networking for full-duplex point-to-point Ethernet communication. The IP core consists of three sub-modules for time synchronization, traffic shaping and Ethernet MAC communication.
