Time Sensitive Networking for Industry 4.0 and Automotive
Embedded sectors such as automotive and industrial have emphasized the need for real-time system solutions not only within their device, but also across their network. For instance, a smart food production line, or a network of devices and sensors in oil and gas industry equipped with an automation system interface (e.g. OPC UA) can face major challenges without deterministic communications between the different network components. To address real-time challenges through the networks, Time Sensitive Networking (TSN) was introduced by IEEE 802.1 WG. TSN consists of standards that guarantee a deterministic behavior to deliver high priority industrial traffic with low latency and infinitesimal packet loss through the Ethernet line across the network, while having other Ethernet traffic carried through. Various standard are introduced within TSN projects, yet to satisfy the current industry real-time expectations, three critical protocols are chosen for this study. 1) IEEE 802.1AS or time synchronizer (gPTP) based on IEEE 1588 2) IEEE 802.1Qav or Traffic Shaper specifying Credit-Based Shaper 3) IEEE 802.1Qbv or enhanced traffic scheduler. Additionally, the usage of some of the other TSN protocols in industry will be covered. Providing hands-on examples, this paper expounds on the current TSN project at Intel®, and the approach in which the new Linux based SW solution as well as the Intel® developed hardware and driver can be implemented to achieve the standards mentioned above.
