Publication: IEEE 802.1DG™-2025 Time-Sensitive Networking Profile for Automotive In-Vehicle Ethernet Communications

This standard specifies profiles for bounded latency automotive in-vehicle bridged IEEE 802.3 Ethernet networks based on IEEE 802.1 Time-Sensitive Networking (TSN) standards.

This standard provides information to automotive vendors and suppliers to help them with the design of vehicular systems enabling bounded latency in automotive in-vehicle networks. It also addresses the use of features from IEEE 802.1 standards to meet the bandwidth, latency, and synchronization needs for communications within automotive vehicles. As IEEE 802.1 standards are broad and intended for use in a variety of environments, this standard determines the features from IEEE 802.1 standards that are directly applicable to automotive in-vehicle networks and suggests how these features are used, including recommendations about how to configure optional parameters.

IEEE Std 802.1DG is a key step forward to using standard Ethernet networks in the automotive industry. This work facilitates the adoption of standard Ethernet bridged network in vehicles to address industry demand on developments toward autonomous and software-defined vehicles.

IEEE Std 802.1DG is available at the IEEE Standards Store and at IEEE Xplore.
