Cover Story (view full-size image): The IEEE 802.1Q-2018 standard embeds in Ethernet bridges novel features that are very important for automated driving, such as the support for time-driven communications. However, cars move in a world where unpredictable events may occur and determine unforeseen situations. To properly react to such situations, the in-car communication system must support event-driven transmissions with very low and bounded delays. This work addresses the benefits of a novel traffic management scheme, called EDSched, for IEEE38802.1Q bridges and end nodes that provides explicit support for a new traffic class, the event-driven real-time class. The paper presents the EDSched approach and provides the performance evaluation. EDSched works at the MAC layer and builds upon the mechanisms defined in the IEEE 802.1Q-2018 standard.
