AIRCRAFT COMMUNICATIONS NETWORK WITH DISTRIBUTED RESPONSIBILITY FOR COMPATIBILITY CONFIRMATION
First Claim
1. An aircraft communications network comprising:
- a communications bus;
a first network device communicatively coupled with the communications bus, the first network device configured to publish on the communications bus a configuration manifest that describes a compatible configuration of hardware and software for the aircraft communications network; and
a second network device communicatively coupled with the communications bus, the second network device configured to;
receive the configuration manifest from the first network device over the communications bus;
compare the configuration manifest to a second hardware and software profile that describes the second network device; and
disable outputs of the second network device in response to detecting a difference between the configuration manifest and the second hardware and software profile.

Abstract
Aircraft communications networks, network devices, and methods of determining compatibility on an aircraft communications network are disclosed herein. The aircraft communications network includes, but is not limited to, a communications bus, a first network device, and a second network device. The first network device is communicatively coupled with the communications bus and is configured to publish on the communications bus a configuration manifest that describes a compatible configuration of hardware and software for the aircraft communications network. The second network device is communicatively coupled with the communications bus and is configured to receive the configuration manifest from the first network device over the communications bus, compare the configuration manifest to a second hardware and software profile that describes the second network device, and disable outputs of the second network device in response to detecting that the configuration manifest differs from the second hardware and software profile.

11. A network device for an aircraft communications network, the network device comprising:
-
a computer hardware component including an input/output (I/O) portion configured for connecting to an aircraft communications bus; and a software component loaded into the computer hardware component, wherein the computer hardware component and the software component cooperate to configure the network device to; receive a configuration manifest through the I/O portion; compare the configuration manifest to a hardware and software profile that describes the computer hardware component and the software component; and disable outputs from the network device through the I/O portion in response to detecting that the configuration manifest differs from the hardware and software profile. - View Dependent Claims (12, 13, 14, 15)

16. A method of determining compatibility of a network device with an aircraft communications network, the method comprising:
-
publishing on a communications network, by a first network device, a configuration manifest that describes a compatible configuration of hardware and software for the aircraft communications network; receiving, at a second network device, the configuration manifest; and comparing, at the second network device, the configuration manifest to a second hardware and software profile that describes the second network device. - View Dependent Claims (17, 18, 19, 20)
