AIRCRAFT COMMUNICATIONS NETWORK WITH DISTRIBUTED RESPONSIBILITY FOR COMPATIBILITY CONFIRMATION

摘要

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.

主权项

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.
