A high availability aircraft network architecture incorporating smart points of presence (SPoP) is disclosed. In embodiments, the network architecture divides the aircraft into districts, or physical subdivisions. Each district includes one or more mission systems (MS) smart network access point (SNAP) devices for connecting MS components and devices located within its district to the MS network. Similarly, each district includes one or more air vehicle systems (AVS) SNAP devices for connecting AVS components and devices within the district to the AVS network. The AVS network may remain in a star or hub-and-spoke topology, while the MS network may be configured in a ring or mesh topology. Selected MS and AVS SNAP devices may be connected to each other via guarded network bridges to securely interconnect the MS and AVS networks.

A method that includes operating a bus monitoring system having at least one interface configured to be coupled to at least one communication bus and receive bus traffic transmitted over the communication bus(es). The method also includes, using a device authentication system of the bus monitoring system, analyzing the bus traffic received via the at least one interface. Analyzing the bus traffic includes obtaining a message in the bus traffic (where the message identifies a source), identifying a support vector machine that corresponds to the source of the message, applying a wave transform to a waveform of the received message in order to generate a transformed waveform, inputting the transformed waveform to the identified support vector machine, and taking action in response to the identified support vector machine determining that the transformed waveform or the associated information does not correspond to the source.

Systems and methods for data acquisition utilizing spare or unused databus capacity are provided. In one example aspect, the system includes a vehicle that includes an engine and a controller. The controller generates a data file indicative of Continuous Engine Operation Data (CEOD). The data file is transmitted over a serial databus to a bus recorder. Particularly, the data file is continuously generated by the controller and stored in a buffer. The available bandwidth of a transmission frame for the serial databus is determined. A portion of the data file is retrieved from the buffer based at least in part on the determined bandwidth. The portion of the data file is divided into relatively small transmission payloads and packed into the available bandwidth of the transmission frame. This process is repeated on a continuous basis and the bus recorder records the data. The data file is then reconstituted and decoded.

A method of operating a communication adapter of a gas turbine engine of an aircraft includes receiving a plurality of time series data at the communication adapter from an engine control of the gas turbine engine. The method also includes recording a plurality of internal sensor data of an internal sensor system of the communication adapter. The method further includes correlating the time series data with the internal sensor data based on an alignment in time to form an enhanced data set and transmitting the enhanced data set from the communication adapter to an offboard system.

Systems and methods for reconfigurable on-vehicle data routing are provided. In one embodiment, a data link communication system comprises: a router to communicate with at least one communication bus and at least one data bus, and monitor data communicated over the communication data buses, wherein the communication bus communicates data link messages with an off-vehicle service provider system, wherein the data bus transports data between the router and a plurality of on-vehicle systems; a routing control logic; and a conditional logic database, wherein the database comprises definitions of one or more datatypes and definitions for at least one data forwarding command; wherein, in response to receiving a first set of data associated with a datatype defined by the database, the logic executes the at least one data forwarding command to control the router to output a second set of data to one or more of the plurality of on-vehicle systems.

Methods and systems are provided for a transportation vehicle. One method includes detecting, by a first system on chip (“SOC”) of a seat box on a transportation vehicle that a first seat device is operational and usage of a second SOC of the seat box by a second seat device is below a first threshold level, the first SOC operationally coupled to the second SOC by a peripheral link, the seat box providing a network connection to the first seat device and the second device; allocating resources of the first SOC and the second SOC to the first seat device; and modifying usage of the second SOC by the first seat device, in response to a change in resource usage of the second SOC.
