Publication – IEEE 802.1DP™-2025 / SAE AS6675 Time-Sensitive Networking Profile for Aerospace Onboard Ethernet Communications

This standard specifies profiles of IEEE 802.1 Time-Sensitive Networking (TSN) and IEEE 802.1 Security standards for aerospace onboard bridged IEEE 802.3 Ethernet networks. The profiles select features, options, configurations, defaults, protocols, and procedures of bridges, end stations, and Local Area Networks to build deterministic networks for aerospace onboard communications.

IEEE Std 802.1DP / SAE AS6675 provides a Time-Sensitive Networking (TSN) profile specification for designers and implementers of aerospace IEEE Std 802.3 Ethernet networks to support a wide range of aerospace applications. As IEEE 802.1 standards are broad and intended for use in a variety of environments, this standard selects the features from IEEE 802.1 standards that are directly applicable to aerospace onboard networks, specifies how to use these features as part of a set of well-defined interoperable profiles, and provides guidance on configuration, management, and monitoring. In so doing, this standard facilitates communications within aerospace platforms to meet the reliability, bandwidth, latency, and synchronization needs of aerospace applications. It also provides necessary and valuable information to airframers, system integrators, and suppliers to help with the design of aerospace systems with standard IEEE 802.3 Ethernet onboard networks.

IEEE 802.1DP / SAE AS6675 is a great achievement made possible with broad participation from the aerospace and networking industry. This work is essential to the adoption of standard Ethernet bridged networks in onboard and in-vehicle networks for aerospace and defense use cases.

IEEE 802.1DP / SAE AS6675 is available at the IEEE Standards Store and at IEEE Xplore.
