Types of data

Future-proof also means a path toward fully autonomous driving (up to Level 5); thus, the architecture includes availability, resiliency and safety standards. One way to reach data communication resiliency and structural redundancy is through a ring topology, enabling multicast protocols and data validity checking.

On the software side, it is essential for a distributed zone topology to handle a mix of very different packet types to accommodate data ranging from a short control message to high-throughput sensor and infotainment data. All of these traffic types additionally vary in latency, jitter, synchronization and error-rate requirements. In short, they vary in terms of quality-of-service (QoS) needs.
