Zonal Architectures are positioned to revolutionize vehicles by allowing OEMs to decrease wiring harness weight and set the foundation for more scalable architectures required for full SDVs. However, the transition to zonal imposes significant new technological challenges. Unlike statically configured legacy architectures that physically isolate each domain to achieve performance, safety, and security, zonal architectures feature multiple ethernet switches in a richly connected topology and the ethernet links between the switches may carry mixed criticality traffic from multiple domains or applications. This dynamic environment requires OEMs to adopt dynamic new technologies to manage it.
