A unified Car-IT Communication-Architecture: Network switch design guidelines

Rising communication needs in transportation systems due to meshed control circuits and complex sensor technology like lidar, radar and cameras lead to increasing wiring harness and system complexity. To solve this, we made an approach for a unified car-IT communication-architecture based on IEEE 802.3 switched Ethernet for use in the vehicular environment. In this paper, we present the requirements for and realization of the core-network components to enable deterministic communication and the corresponding real-time calculus for system verification.
