AvionicsData: Barramentos Aviônicos de Alta Largura de Banda e Redes Determinísticas AFDX

O AvionicsData fornece especificações de engenharia de rede e arquiteturas de switch para barramentos aeroespaciais, roteando controles de voo críticos, fluxos de radares e telas de cockpit em backbones ARINC 664 (AFDX) e TTEthernet tolerantes a falhas.

AvionicsData Deterministic ARINC 664 / TTEthernet Avionics Bus Architecture

Virtual link traffic policing, dual-redundant fiber switches, and sub-microsecond PTP clock sync

Central System: AFDX Core Switch - Virtual Link Traffic Regulator

Aviation Architecture Nodes

  • Flight Control Computer LRU
  • Deterministic AFDX Fiber Switch
  • Time-Triggered Ethernet (TTE) Hub
  • High-Definition Cockpit Display Node
  • Crash-Survivable Optical Data Sink

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)
