Automotive Ethernet connectivity is a key enabler of new, zonal architectures in automotive design and supports automotive megatrends like personalization, autonomy, and electrification. Ethernet has become the ubiquitous technology for backbone network connectivity across many industries, and it’s proving to be a critical technology in the automotive world as well.
In existing automotive architectures, edge node connectivity is provided by non-Ethernet legacy networks. As systems transition to zonal architectures based on Ethernet connectivity and centralized processing, maintaining legacy network edge connectivity dictates the need for gateways to bridge from Ethernet to these legacy networks. However, bridging adds complexity, latency, and inflexibility, making systems difficult to scale and reuse.
Maintaining Ethernet all the way to the edge nodes removes this bridging function, providing a fully optimized Ethernet architecture utilizing time sensitive networking (TSN) to deliver quality of service and flexible address-based routing for dynamic network creation. The broad physical layer portfolio enables the optimal solution for all situations.
