Maximizing Interoperability in Mixed IEEE 802.1AS-2011 and AS-2020 Networks

by Kilian Brunner and Dr. Martin Ostertag | ZHAW Zurich University of Applied Sciences

Abstract

During the transition to IEEE 802.1AS-2020, many TSN setups will mix AS-2020 and legacy AS-2011 devices. AS-2020 Grandmasters are still limited, but also AS-2011 switches or endnodes can't always be upgraded. A key change in AS-2020 is the peer delay mechanism. To ensure compatibility, AS-2020 offers configurable mechanisms. Our talk explores maximizing interoperability without explicit port configs, presenting real-world-tested strategies for robust time sync in industrial TSN environments.

Do We Already Have TSN Networks? Myths vs. Realities

What truly qualifies a network as "TSN-capable"? Is a TSN switch sufficient, or does it lack centralized stream control and deterministic traffic shaping?

Interpretation of IEC/IEEE 60802 Profile for Virtualization

The IEC/IEEE 60802 profile outlines the TSN architecture for industrial automation but omits node virtualization. This presentation investigates how the profile can be applied in virtualization contexts to manage aggregated nodes and shared links.

How does TSN align with Virtual PLCs including Motion?

The presentation presents a fully virtualized control architecture where Linux-based virtual PLCs communicate deterministically with PROFINET IRT devices via TSN.
