A method for monitoring data integrity on a network includes reading error data from an interface associated with a particular link of the network in response to error data being present in a message received on the particular link. The method also includes creating a report message including the error data and transmitting the report message to a network monitoring algorithm operable on a processor circuit. The network monitoring algorithm is configured to determine a data integrity of the particular link based on the error data.

Network including data integrity monitoring

A method and apparatus for managing a managed device on a network. An agent is run on the managed device. During runtime of the agent on the managed device, the agent receives dynamic trap parameter update values from network management station software running on a manager computer. The agent uses the dynamic trap parameter update values to set dynamic trap parameter values including trigger parameter values defining conditions for sending a dynamic trap. After setting the dynamic trap parameter values, the agent monitors the managed device to identify occurrence of an event that satisfies the conditions defined by the trigger parameter values. In response to identifying the occurrence of the event, the agent sends the dynamic trap to the network management station software running on the manager computer.

Dynamic trap for simple network management protocol

A system includes a first and at least one second processing circuit, a configuration engine, and a switch. The configuration engine stores a virtual link configuration for a plurality of virtual links, which indicates a priority and a predetermined network pathway for communicating data packets from the first processing circuit to the at least one second processing circuit. The configuration engine automatically assigns priority to a first virtual link of the plurality of virtual links based on at least one of latency or jitter. The switch receives a first data packet from the first processing circuit. A first virtual link identifier is extracted from the first data packet. A first priority and a first predetermined network pathway corresponding to the first virtual link identifier from the virtual link configuration are retrieved. The first data packet is transmitted along the first predetermined network pathway based on the first priority.

Systems and methods for automatic priority assignment for virtual links

A system for an airborne platform includes a network controller, a first subsystem having a number of devices configured to communicate a first data type, and a second subsystem having a number of devices configured to communicate a second data type. The network controller includes a processing circuit and is communicably coupled to the first subsystem and to the second subsystem. The processing circuit is configured to receive data relating to the first data type over a first plurality of communication channels and data relating to the second data type over a second plurality of communication channels. The processing circuit is further configured to multiplex the data relating to the first data type and the second data type to a multiplexed data stream configured for communication over a single communication channel. The processing circuit is further configured to transmit the multiplexed data stream over a data transmission line.

Shared networking infrastructure with multi-link channel bonding

A display system may include a display device and a controller. The display device may include a bezel with a bezel light sensor and a screen set within the bezel. The controller may be configured to receive a flashing light signal via the bezel light sensor, generate a response to a set of coded information in the flashing light signal, and provide the response to the set of coded information via the screen. The flashing light signal may be transmitted by a light generator of an electronic device. A filter may be couplable to at least one of the electronic device at a position proximate to the light generator or the display device at a position proximate to the bezel light sensor. A wavelength of the flashing light signal may be a first wavelength. The filter may be configured to convert the first wavelength to a second wavelength.

System and method for data transfer via a display device including a bezel light sensor

A device for avionics full-duplex switched Ethernet (AFDX) communication can include a transmit port for transmitting AFDX data and a processor. The processor can be configured to obtain AFDX data frames for transmission over a plurality of sub-virtual links (subVLs) of a virtual link (VL), and maintain, for each of the plurality of subVLs, a corresponding data queue by storing AFDX data frames associated with that subVL in the corresponding data queue. The processor can transmit the AFDX data frames from the plurality of data queues on the plurality subVLs via the transmit port according to a scheduling policy that is based on subVL prioritization. The scheduling policy that is based on subVL prioritization can include static priority (SPn) scheduling, earliest deadline first (EDF) scheduling, or least laxity first (LLF) scheduling.

Scheduling mechanisms for end system SUBVLs

A display system may include a bezel. The bezel may include a bezel light sensor. The display system may include a screen set within the bezel. The display system may include a controller coupled to the bezel light sensor. The controller may be configured to receive a flashing light signal via the bezel light sensor. The flashing light signal may include a set of coded information. The flashing light signal may be transmitted by a light generator. The controller may be configured to generate a response to the set of coded information. The controller may be configured to provide the response to the set of coded information via the screen.

An avionics computer system steganographically encodes streaming data, and serial buffer output data into a current avionics display corresponding to the system generating the data. The encoded pixels are limited to black spaces within color channels of the display. The data is encoded into reproducible blocks within the display and the blocks are copied within the display for error correction.

Display steganography for active correlation of data

A widget for displaying a quick response (QR) code is populated with state data pertinent to a system malfunction where the system does not otherwise have a viable method for supplying such data for analysis. The widget is generated and populated by a graphics server that complies with avionics certification standards. The widget allows multiple pages of data by either automatically repopulating the widget with a new QR code or accepting an input indicating the ability to continue.
