Explore the fundamentals of Time Sensitive Networking (TSN) and Deterministic Networking (DetNet) for real-time systems in this informative conference talk. Delve into the origins of TSN and DetNet in Audio-Video Bridging's IEEE standards, and discover how these technologies enable the design of distributed systems that minimize network traffic jitter. Learn how real-time systems can scale beyond single units by expressing requirements to the network itself, ensuring traffic reliability within specified limits. Gain insights into the current state of TSN development in the Linux kernel, its future directions, and potential applications. Understand the compatibility of TSN with off-the-shelf solutions and its alignment with the open-source model. The speaker, Henrik Austad from Cisco Systems, shares his expertise in Linux kernel real-time performance profiling, low-level audio development, and TSN implementation.
