Application of Ethernet-based networks in the autonomous and automated vehicles requires safe and efficient resource management policy. The network components must not only handle high volume of sensor data but also safely accommodate dynamics in system behavior, e.g. detect permanent failures, switch between different driving modes (city/highway), incorporate car-2-x communication etc. This is currently manageable only by using static network configuration, due to the safety concerns, leading to resource overprovisioning under almost all conditions or unfulfilled design requirements. In this work we present an alternative solution which, through protocol-based synchronization and fine-grained re-configuration, allows traffic isolation, fault recovery and controlled adjustments of network performance. This enables cost saving, multi-mode network functionality at low overhead as well as new system functions and improved user experience by dynamic over-the-air network operation. We offer a detailed evaluation of our approach in a demonstrator setup as well as a simulation and comparison with state-of-the-art approaches.

基于以太网的网络在自主和自动化车辆中的应用需要安全有效的资源管理策略。网络组件不仅必须处理大量传感器数据，还必须安全地适应系统行为的动态变化，例如检测永久性故障、在不同驾驶模式（城市/高速公路）之间切换、结合 car-2-x 通信等。这是目前可以管理的出于安全考虑，只能使用静态网络配置，导致几乎所有条件下的资源过度配置或未满足的设计要求。在这项工作中，我们提出了一种替代解决方案，通过基于协议的同步和细粒度的重新配置，允许流量隔离、故障恢复和网络性能的受控调整。这样可以节省成本，低开销的多模网络功能以及新的系统功能和通过动态无线网络操作改善用户体验。我们在演示器设置中对我们的方法进行了详细评估，并与最先进的方法进行了模拟和比较。
