Architectural Layers & Protocol Stacks

Deterministic Physical Layer & Optical Fiber (1000BASE-T1 / ARINC 818 High-Speed Video Fiber): Routing gigabit-rate sensor and radar streams with complete immunity to lightning strikes and electromagnetic interference (EMI).
Time-Triggered Media Access & Synchronization (SAE AS6802 TTEthernet / IEEE 802.1AS PTP): Synchronizing all onboard computers to a fault-tolerant global clock with jitter under 1 microsecond.
Virtual Link Policing & Traffic Isolation (Bandwidth Allocation Gap (BAG) Hardware Shapers): Preventing babbling-idiot faults by strictly policing transmission intervals and allocating dedicated bandwidth per Virtual Link.
Integrated Modular Avionics (IMA) Transport (ARINC 653 Sampling & Queuing Ports): Interfacing RTOS software partitions directly with network frames without CPU interrupt thrashing.

Flight Telemetry Metrics: < 1 µs (Global Clock Synchronization Jitter) | Zero Loss (Virtual Link Packet Drop Guarantee) | 10 Gbps (High-Speed Fiber Avionics Bandwidth) | DO-254 DAL A (Hardware Switch Silicon Level)
