Abstract: The node communication controller (NCC) suitable for use in a line-replaceable unit (LRU) of a modular avionics system may include one or more embedded processors configured to host one or more functions associated with at least one avionics module of an avionics system, an input/output (I/O) controller, and one or more I/O ports, wherein the I/O controller is configured to route data between the one or more embedded processors and the at least one avionics module via the one or more I/O ports and a network communication bus, wherein the I/O controller is further configured to route data between a host processor of the LRU and an additional avionics module via the one or more I/O ports and the network communication bus.

Abstract: A ‘per flow’ flow monitor is operatively associated with each ingress port of the switch of the data network, for monitoring the arrival data flow on each flow in defined traffic constraint envelopes containing frames. An eligibility time computation mechanism computes an eligibility time at which arriving frames on each flow will be conformant to the defined traffic envelope to the ingress port given past frame arrivals on that same flow. A holding mechanism holds the arriving frames on each flow until the eligibility time is reached. A release mechanism releases the arriving frames on a flow at the eligibility time. The flow monitor, computation mechanism, holding mechanism, and release mechanism cooperate to provide an ‘per flow’ traffic shaping function in conformance with delay and delay-jitter bound, frame loss probability, and bandwidth provisioning requirements, thus allowing the switch to enforce the traffic constraint envelope for each flow.

Abstract: Each switch of the data network includes a number of switch ingress ports for receiving arrival data flow. An aggregate flow monitor is operatively associated with each ingress port for monitoring the aggregate arrival data flow in defined traffic constraint envelopes containing frames. An eligibility time computation mechanism computes an eligibility time at which arriving frames to an ingress port will be conformant to the defined traffic envelope to the ingress port given past frame arrivals. A holding mechanism holds the arriving frames to the ingress port until the eligibility time is reached. A release mechanism releases the arriving frames for forwarding at the eligibility time. The aggregate flow monitor, the eligibility time computation mechanism, the holding mechanism, and the release mechanism cooperate to provide an aggregate traffic shaping function, thus allowing the switch to enforce the traffic constraint envelope for each ingress port.

Abstract: A high integrity, high availability avionics display architecture for an avionics display system. The architecture includes a plurality of display processing computers (DPC) and a plurality of display integrity feedback interfaces. Each DPC includes at least two independent processing channels.

A number of display integrity feedback interfaces from the displays of the avionics display system provide integrity by allowing the integrity monitor functions to detect faults within the display signals and/or originating from the displays.
