Abstract: An embodiment of an open data network system facilitates communication between applications related to operation of a vehicle, such as an aircraft, and re-use of components in different systems and implementations. A switch/router communicates data between on-board systems. A server communicates with the switch/router and provides at least one of processing services and storage services to the on-board systems via the switch/router. A network manager communicates with the switch/router to direct the switch/router in selectively allowing access between the on-board systems. In other embodiments, an avionics interface unit communicates with the switch/router and enable communications between at least one avionics system and at least one of the on-board systems.

Abstract: Remotely performed maintenance of a transportation unit such as an aircraft is disclosed, wherein the maintenance is performed utilizing a networked environment. In one implementation, a first network, located within the mobile transportation unit, is accessed from a second network, located externally to the mobile transportation unit. Having remotely assessed the first network, communication with one or more assets of the mobile transportation unit, which are connected to the first network, is possible. Maintenance operations are then performed by exchanging data and commands with the assets of the mobile transportation unit.
