Summary:Due to the benefits of better bandwidth and reliability, the automotive industry is moving towards Ethernet-based in-vehicle network (IVN) systems as the number of onboard electronic control units has increased. Considering that before long the well-known controller area network (CAN) will still be considered a standard protocol, our earlier work introduced a high-availability seamless redundancy (HSR)-based Ethernet network architecture that provides IVNs with fault tolerance, called seamless CAN. However, HSR is known for its redundant traffic generated for fault tolerance, which is a disadvantage in bandwidth-limited IVN systems. Therefore, in this paper, we propose a traffic-effective architecture for seamless CAN-based networks. We compared the proficiency of different traffic-reduction approaches as they were applied to our proposed architecture. Extensive simulation results showed that our proposed solution could reduce up to 54% of the total network traffic compared to a conventional architecture while still being able to guarantee a high level of fault tolerance.
