Abstract

A networking architecture for air/ground data communications which implements a single network-layer protocol between a customer aircraft network interface and a customer ground system network interface, which routes data between customer aircraft and associated customer ground systems, and which eliminates the need for network-layer protocol conversion by service provider ground systems.

Claims

1. An end-to-end network for air/ground data communications between a customer aircraft and a customer ground facility, the network comprising:

on the aircraft, a first radio for communicating with the end-to-end network and an application gateway for connecting the first radio with other equipment on the aircraft by network protocol conversion; and

on the ground, a second radio for communicating with the first radio and a ground network for transmitting the data communications between the second radio and the customer ground facility,

wherein the data communications among the first radio, the second radio and the ground network use a common network protocol so that network-layer protocol conversions between the aircraft and the ground network are not required.

2. The end-to-end network of claim 1, wherein some or all of the ground network is a part of the worldwide Internet.

3. The end-to-end network of claim 1, wherein the ground network uses network control and routing protocols which are interoperable with the worldwide Internet.

4. The end-to-end network of claim 1, wherein the ground network uses network control and routing protocols which are interoperable with the Aeronautical Telecommunications Network (ATN).

5. An end-to-end network for air/ground data communications between customer aircraft and customer ground facilities, the end-to-end network comprising:

on the aircraft, first and second application gateways representing first and second network interface points of a network supporting a legacy air/ground networking protocol, and one network interface point for a network supporting a legacy ground/ground networking protocol; and

on the ground, a radio for communicating with the aircraft and a ground network supporting the legacy ground/ground networking protocol;

wherein the second application gateway and the network interface point jointly support all customer-relevant protocol conversions and processing required to provide internetworking between a) the legacy air/ground networking protocol and the legacy ground/ground networking protocol, thereby allowing bypass of a service-provider application gateway on the ground.

6. The end-to-end network of claim 5, wherein some or all of the ground network is a part of the worldwide Internet.

7. The end-to-end network of claim 5, wherein the legacy ground/ground networking protocol is interoperable with the worldwide Internet.

8. The end-to-end network of claim 5, wherein the legacy ground/ground networking protocol is interoperable with the Aeronautical Telecommunications Network (ATN).

9. The end-to-end network of claim 5, wherein at least one of the second application gateway and the network interface point implements a store-and-forward capability.

10. The end-to-end network of claim 5, wherein at least one of the first and second application gateways supports protocol configuration tailoring remotely.

11. The end-to-end network of claim 5, wherein user data is encrypted and passed transparently through the ground network without decryption in the ground network.
