TSN/A Conference 2025 | September 24, 11:30 a.m.Maximizing Interoperability in Mixed IEEE 802.1AS-2011 and AS-2020 Networks

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.
