METHODS AND APPARATUS PROVIDING AN AIRBORNE E-ENABLED ARCHITECTURE AS A SYSTEM OF SYSTEMS

摘要

A network architecture for implementation in a vehicle is described that comprisesan Ethernet gateway module (EGM) and network interface module (NIM). The EGMcomprises an Ethernet switch and router therein and is configured to providean open data network (ODN) connection to the network architecture for a pluralityof open data network devices. The NIM is configured to provide an isolated datanetwork and comprises an Ethernet switch to connect a plurality of secure devicesto an isolated data network (IDN), the secure devices related to operation andnavigation of the vehicle, a router and a gateway/router. The router is configuredto interface the IDN to the open data network connections and comprises a packetfiltering function to determine which, if any, data from the ODN may be passedthrough to the IDN and applied to operation and navigation of the vehicle via thesecures devices connected to the IDN. The gateway/router provides network addressand protocol translation to connect the IDN to a secure common data network associatedwith vehicle operation. The architecture provides segregation between networkdevices in the IDN and CDN related to operation and navigation of the vehicle,and network devices in the ODN.
