Ethernet and Ethernet-AVB for automotive applications

摘要

As automotive technology evolves to provide increased features and services, market demands necessitate a more robust and higher-performing networking architecture. Existing automotive connectivity solutions were developed before the advent of in-car HD resolution screens, automotive cameras, advanced safety systems, and sophisticated infotainment. As these products and services become available to mainstream models, an easy-to-use and cost-effective in-car connectivity solution is needed. Ethernet technology is well-suited for this application, as it can meet these needs and allow for broad deployment across all automotive market segments. It is by far the most widely deployed networking method, and the technology and IP are available from numerous manufacturers. Engineers are very familiar with Ethernet, and a realistic technology roadmap is readily available. Moreover, the standards, including IEEE's Audio Video Bridging over Ethernet (AVB), are truly open, with lower development risks and costs.
