P802.1DP – TSN for Aerospace Onboard Ethernet Communications
IEEE P802.1DP / SAE AS6675 is a joint project of IEEE 802 and SAE Avionics Networks AS-1 A2 to define TSN profiles for aerospace. This joint work will provide a jointly developed standard that is both an SAE and an IEEE standard.
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.
This standard specifies profiles for designers, implementers, integrators, and certification agencies of deterministic IEEE 802.3 Ethernet networks that support a broad range of aerospace onboard applications including those requiring security, high availability and reliability, maintainability, and bounded latency.
