Real-time Ethernet using OPC UA PubSub over TSN (demonstrator)

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

A demonstrator with a 2-node network using embedded 4-core Intel Apollo Lake Linux systems with Intel I210 controllers was setup in order to demonstrate the real-time performance of OPC UA PubSub over TSN. Technical and configuration data of the main components of the demonstrator can be obtained through the standard OSADL QA Farm interfaces where they are integrated in rack "f".

Latency
Please note that the recorded values of this plot represent the maximum of subsequent 5-min intervals. One test interval consists of 1.000.000 packets. The round-trip time is expected to be a multiple of 250 µs. The best possible round-trip time is 1ms.
