Abstract: 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.

Each of the first plurality of flight display units includes a first physical network interface configured to communicate with one of the first plurality of flight display units, a second physical network interface configured to communicate with another of the first plurality of flight display units, and a flight display circuit. The flight display circuit is configured to receive avionics data via the first physical network interface and determine whether the avionics data is destined for the flight display unit receiving the data. The flight display circuit is configured to send the avionics data to the other flight display unit of the plurality of the first plurality of flight display units via the second physical network interface.

Abstract: An improved AFDX switch, as described herein, can include an embedded integrity monitoring module that is functionally fault-independent of the switching module or other components of the AFDX switch. The integrity monitoring module can include a delay monitoring module for monitoring delays of data packets within the AFDX switch and/or a routing module for monitoring or detecting data packets routing errors or failures. The delay monitoring module can assign a timestamp to a data frame at arrival to the AFDX switch, determine a time delay of the data frame within the AFDX switch based on the timestamp, and compare the time delay to a threshold value to detect erroneous time delays. The routing monitoring module can compare the input port and/or the output port at which the data frame arrives while in the AFDX switch to the corresponding preassigned input port or output port to detect routing failures.

Abstract: Improved AFDX switches can handle various types of data traffics beyond a predefined AFDX related communication protocol. An AFDX switch can determine a mismatch between a MAC address of a received data frame and a MAC address constant specific to the predefined AFDX related protocol. In response to the mismatch, the AFDX switch can determine a data traffic type associated with the data frame based on a first portion of a header of the data frame. The AFDX switch can compare, responsive to determining a data traffic type associated with the data frame, a second portion of the header of the data frame to identifiers of a plurality of communication flows. Responsive to identifying a communication flow with a matching identifier, the AFDX switch can route the data frame based on communication flow parameters of the identified communication flow.

Abstract: A system and method is disclosed for identification and response to an unauthorized transmission to a networked critical system. The invention employs a pre-defined parameter which matches trusted sources with defined destinations to enable secure access to the networked critical system. Once the method receives a transmission to the destination, it filters the transmissions based on specific architecture constraints. Should the transmission survive, the method continues with a plurality of layers of system level checks to verify the source matches the pre-defined parameter of a trusted source. Should the transmission fail any of the layers of system level checks, the method provides an appropriate response. Once the transmission survives, the method continuously monitors the data stream for possible threats and allows access the transmission to reach the destination and the networked critical system.
