    摘要： A network architecture for implementation in a vehicle is described that comprises an Ethernet gateway module (EGM) and network interface module (NIM). The EGM comprises an Ethernet switch and router therein and is configured to provide an open data network (ODN) connection to the network architecture for a plurality of open data network devices. The NIM is configured to provide an isolated data network and comprises an Ethernet switch to connect a plurality of secure devices to an isolated data network (IDN), the secure devices related to operation and navigation of the vehicle, a router and a gateway/router. The router is configured to interface the IDN to the open data network connections and comprises a packet filtering function to determine which, if any, data from the ODN may be passed through to the IDN and applied to operation and navigation of the vehicle via the secures devices connected to the IDN. The gateway/router provides network address and protocol translation to connect the IDN to a secure common data network associated with vehicle operation. The architecture provides segregation between network devices in the IDN and CDN related to operation and navigation of the vehicle, and network devices in the ODN.

    摘要翻译： 描述了一种用于在车辆中实现的网络架构，其包括以太网网关模块（EGM）和网络接口模块（NIM）。 EGM包括其中的以太网交换机和路由器，并且被配置为向多个开放数据网络设备提供到网络架构的开放数据网络（ODN）连接。 NIM被配置为提供隔离的数据网络，并且包括以太网交换机以将多个安全设备连接到隔离数据网络（IDN），与车辆的操作和导航相关的安全设备，路由器和网关/路由器 。 路由器被配置为将IDN接入开放数据网络连接并且包括分组过滤功能，以确定来自ODN的哪些数据（如果有的话）可以被传递到IDN，并且经由固定应用于车辆的操作和导航 连接到IDN的设备。 网关/路由器提供网络地址和协议转换，以将IDN连接到与车辆操作相关联的安全通用数据网络。 该架构提供了与IDN中的网络设备和与车辆的操作和导航以及ODN中的网络设备有关的CDN之间的隔离。
