Summary

Ethernet is already in use in many safety-critical systems such as avionics and industrial control, and is gaining traction in automotive systems due to the significant bandwidth needs of modern infotainment, active safety, and autonomous driving applications. This course will cover multiple aspects of real-time and dependable Ethernet communication: scheduling, synchronization, bandwidth reservation, preemption, and fault tolerance. The course covers the latest technology standards developed within IEEE 802, focusing in particular on the Time-Sensitive Networking (TSN) standards developed within the IEEE 802.1 Working Group. The course content is very closely aligned with technology that is currently developed and planned to be used in many safety-critical system in industry, with examples from automotive and industrial control applications.
