The new generation of military vehicles is massively digitized and interconnected. In this context, the defense industry is focusing on technology standards to ensure interoperability and an ability to rapidly update platforms in the event of new threats. For this, we offer our Whitepaper explaining why the original Ethernet has limitations and how an implementation of DDS over TSN could be a good solution.
NATO Generic Vehicle Architecture (NGVA) is one such group that is taking standard based approach to platform designs. The Volume III of this standard defines the NGVA Data Infrastructure. This proposal comprises all data types interchanged among the subsystems of the vehicle. But as the heterogeneity of the sources is critical, all data types and communication layers rely on an Ethernet Data Link Layer.
Why DDS over TSN?
Original Ethernet is limited in ensuring real-time communications, which results in sub-optimal network infrastructure.Time-Sensitive Networking (TSN) standards are the evolution of the original Ethernet. They define mechanisms for the real-time communication of data over Ethernet networks.
TSN provides a single, real-time capable, high-bandwidth, fault-tolerant and interoperable network. In combination with DDS, data delivery determinism can be ensured while the overall complexity and cost of the final implementation can be drastically reduced.
