The
IEEE P802.1DP™ project has been established to ensure that experts are involved in defining the use of IEEE 802.1 Time-Sensitive Networking (TSN) for aerospace onboard Ethernet communications. The intent is to develop the
IEEE 802.1DP™
standard jointly between the IEEE 802.1 Working Group and SAE Avionics Networks AS-1 A2 Committee. The more participation, the better this standard will represent the needs of the entire industry.
Participation can include requirements and/or designs for:
- Deterministic latency
- Redundancy
- Security
- Time synchronization
- Other topics related to determinism and reliable communication
The purpose of the IEEE 802.1DP™ standard is to describe the use of Ethernet bridged networks based on IEEE standards in aerospace onboard networks. The IEEE 802.1DP™ 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 aerospace segment does not have profiles of IEEE 802.1 TSN standards. The lack of standardized TSN profiles makes the definition of the aerospace manufacturers’ requirements and the implementation of those requirements by suppliers more difficult and costly. Thus, there is a need to standardize the selection and use of IEEE 802.1 and IEEE 802.3 standards and features in order to be able to deploy secure, highly-reliable converged networks, and enable certification as a basis for compliance and design assurance.
The stakeholders include developers, integrators, aerospace manufacturers and suppliers, test equipment vendors, certification agencies, and users of networking services and components for aerospace.
