Aircraft Priority Network Segmentation for Latency Reduction

The patent segments the aircraft communication network into multiple virtual networks with different priority levels. Critical avionics devices are assigned to high-priority virtual networks while passenger devices use standard-priority networks. This segmentation allows simultaneous operation of multiple networks over shared physical infrastructure, ensuring that critical communications receive guaranteed bandwidth and low latency while maintaining broad network accessibility for all devices.

The patent implements local quality by assigning different quality of service characteristics to different segments of the network. Critical avionics functions receive high-reliability service with guaranteed bandwidth and priority access, while non-critical passenger services operate with standard reliability parameters. This allows the system to maintain complex reliability requirements for safety-critical communications while using simpler shared infrastructure for less demanding applications.

The patent introduces network access points and controllers as intermediary devices that manage priority access automatically. These intermediaries handle the complex tasks of identifying critical devices, allocating priority bandwidth, and controlling access to the aviation communication network. By delegating complex management functions to specialized intermediary components, the system achieves high reliability for critical communications without burdening the overall network architecture with centralized complexity.
