Abstract

A system and method for establishing connectivity between a client device and an on-board computer network of an airplane are provided. The client device is connected for establishing communication with a network such as an enterprise intranet associated with the airplane. A virtual private network is created for establishing communication between a router and the client device. The client device is connected with an on-board server of the airplane via the router while maintaining connectivity between the personal computer and the network.

Claims

1. A method of establishing connectivity between an off-board client device and an on-board computer network of an airplane comprising:

connecting the off-board client device with at least one of an internal network or an external network and initiating, using the off-board client device, a communication session with an on-board server of the airplane connected to a closed on-board data network behind an avionics interface module of the airplane;

creating a virtual private network for establishing communication between a router and the off-board client device; and

connecting the off-board client device with the on-board server of the airplane via the router while maintaining connectivity between the off-board client device and the at least one internal network or external network, and with the closed on-board data network behind the avionics interface module of the airplane.

2. The method of claim 1 further comprising establishing a communication path between the router and an avionic core architecture of the on-board computer network of the airplane.

3. The method of claim 2 wherein the avionic core architecture comprises an open data network and the closed on-board data network and wherein the communication path is established between the router and the closed on-board data network.

4. The method of claim 3 wherein the closed on-board data network comprises an isolated data network accessible only to airplane avionics modules comprising an avionics gateway.

5. The method of claim 3 further comprising sending data received from the router at the closed on-board data network to the open data network for communication with the on-board server of the airplane.

6. The method of claim 1 wherein the off-board client device is connected with the external network, and the external network comprises at least one of:

(a) an Internet;

(b) an airport network;

or (c) a factory network.

7. The method of claim 1 wherein the off-board client device is connected with the internal network, the internal network is an enterprise network, and the off-board client device communicates with the enterprise network.

8. The method of claim 7 wherein the off-board client device is a maintenance control unit and further comprising utilizing the maintenance control unit to interact with the on-board server to perform maintenance analysis functions or loading of software while in communication with at least one of the enterprise network, a factory network, an internet, or an airport network.

9. The method of claim 1 wherein the off-board client device is connected with the internal network and further comprising connecting an Ethernet interface of the router to the internal network;

identifying an Internet Protocol (IP) address of the internal network;

connecting the router to the on-board computer network of the airplane; and

configuring the virtual private network associated with the off-board client device and the router with the IP address obtained from the internal network.

10. The method of claim 1 wherein the on-board server of the airplane is X-windows based.

11. A system for establishing connectivity between an off-board client device and an on-board computer network of an airplane comprising:

a router adapted to communicate with the off-board client device through a virtual private network;

said off-board client device for initiating a communication session with an on-board server of the airplane connected to a closed on-board data network behind an avionics interface module of the airplane and for communicating with at least one of an internal network or an external network; and

said off-board client device for connecting with the on-board server of the airplane via the router while maintaining connectivity between the off-board client device and the at least one internal network or external network, and with the closed on-board data network behind the avionics interface module of the airplane.

12. The system of claim 11 further comprising a communication path established between the router and avionic core architecture of the on-board computer network of the airplane.

13. The system of claim 12 wherein the avionic core architecture comprises an open data network and the closed on-board data network and wherein the communication path is established between the router and the closed on-board data network.

14. The system of claim 13 wherein the closed on-board data network comprises an isolated data network accessible only to airplane avionics modules comprising an avionics gateway.

15. The system of claim 13 wherein the closed on-board data network sends data received from the router to the open data network for communication with the on-board server.

16. The system of claim 11 wherein the off-board client device communicates with the external network, and the external network comprises at least one of:

(a) an Internet;

(b) an airport network;

or (c) a factory network.

17. The system of claim 11 wherein the off-board client device communicates with the internal network, and the internal network is an enterprise network.

18. The system of claim 17 wherein the off-board client device is a maintenance control unit adapted to interact with the on-board server to perform maintenance analysis functions or loading of software while in communication with at least one of the enterprise network, a factory network, an internet, or an airport network.

19. The system of claim 11 wherein the off-board client device communicates with the internal network, an Ethernet interface of the router is connected to the internal network, and an Internet Protocol (IP) address is obtained from the internal network.

20. The system of claim 19 wherein the router is connected to the on-board computer network of the airplane and the virtual private network associated with the off-board client device and the router is configured using the IP address obtained from the internal network.

21. The system of claim 11 wherein the on-board server of the airplane is X-windows based.
