NTN Fabric: Software-Defined In-Orbit Mesh-Routing & Inter-Satelliten-Fabrics

NTNFabric System Architecture

Core architectural topology and protocol interaction of ntnfabric.com

Central System: Space Mesh SDN - In-Orbit Switching

Network Nodes

• Laser ISL 100G
• Segment Routing
• Walker Topology
• Polar Handoff
• Terrestrial Egress

Architectural Protocol Layers

• User & Terminal Access Layer (3GPP Rel-17/18 NR-NTN & IoT-NTN): Direct communication from smartphones and IoT sensors to satellites
• Space-Borne Radio Access (gNodeB / Transponder) (Regenerative Digital Payloads & Bent-Pipe Transparent Processing): In-orbit demodulation, digital beamforming, and spectrum channelization
• Inter-Satellite Mesh & Space Transport (Optical Inter-Satellite Links (OISL) & 60 GHz V-Band Cross-Links): Autonomous multi-hop laser packet routing in vacuum at the speed of light
• Ground Teleport & Core Cloud Ingress (High-Throughput Q/V-Band Gateways & Optical Ground Stations): Terabit feeder link downlinks connected directly to cloud hyperscalers

Key Metrics: 100 Gbps+ (Optical Cross-Link Bandwidth) | <25 ms (LEO Propagation Latency) | ±50 kHz (Doppler Shift Compensation) | 99.999% (Constellation Transport SLA)
