Abstract :	[en] Autonomous driving requires safety considerations and the need of “fail operational” requires redundancy. In the networking portion of a car, this may mean separate networks, possibly of different technologies. Or it could mean a network topology and technology that supports scalable redundancy, like Ethernet TSN. This presentation focuses on IEEE 802.1CB-2017, which is the TSN standard that supports data redundancy through the network. Various network topologies are examined. The relative costs of adding TSN redundancy for these topologies (including some, or all of, the end-stations/ECUs & bridges) are examined for various bandwidth utilizations, along with the expected packet loss. Each topology and bandwidth will be modeled under various bit-rate error values with the results discussed. This presentation aims at providing a clear understanding of the TSN standards that support redundancy, and an understanding of the cost/benefit tradeoffs so proper engineering decisions can be made and proper expectations set.
