Deterministic ethernet protocols
WebDec 15, 2024 · The Time-Sensitive Networking (TSN) technology standardized by IEEE 802.1 is an Ethernet-based networking technology to provide services for applications requiring ultra-low latency and high-precision characteristics. This paper explains what TSN is and how to implement deterministic communication and its core technology. WebTime synchronization has been a secondary concern on many IT networks until recently. Many other Ethernet-based automation protocols, along with additions to IEEE 802.1—such as audio video bridging—emerged from the years of work that went into making Ethernet suitable for industrial and automotive contexts. Still, there is more work …
