Overview - Peer-to-peer - Star topology - Demonstrator (TSN) - Heterogeneous peer-to-peer - Demonstrator (OPC UA PubSub over TSN)

One of the Linux real-time test systems (rack #c, slot #8 at primary position) serves as PTP grandmaster while receiving global time information via NTP in the same way as all other systems. This PTP server is connected via a peer-to-peer link to another real-time test system (rack #0, slot #8 at shadow position) that is configured as PTP slave. As can be derived from the below depicted jitter plots over time, SO_TXTIME flagged packets such as implemented in an OPC UA PubSub scenario can be sent across the peers with a predictable arrival time at the destination peer. The two computer systems, the PTP grandmaster and the PTP slave, are equipped with an Intel I210-T1 network adapter integrating an Intel I210 network controller.
