SpaceMeshNetwork: Roteamento em Malha Laser Autônoma e Comutação Orbital

SpaceMeshNetwork High-Throughput Intersatellite Mesh Routing Architecture

4-way optical crosslink topology with dynamic contact-graph routing (CGR)

Central System: Intra-Plane Laser Terminal (Fore/Aft) - 100 Gbps 1550nm coherent link within orbital plane

Network Nodes

• Intra-Plane Laser Terminal (Fore/Aft)
• Inter-Plane Laser Terminal (Port/Stbd)
• Radiation-Hardened Switch Core
• Contact Graph Routing (CGR) Processor

Architectural Protocol Layers

• Spaceborne PHY/MAC Layer (3GPP Rel-17 TS 38.300): Doppler compensation, HARQ disabling, and timing advance extension.
• Orbital Mesh Routing (CCSDS / Delay-Tolerant Networking): Dynamic topology routing over intermittent laser crosslinks.
• Regenerative Core Processing (OpenRAN / 3GPP CU-DU Split): Onboard user plane function (UPF) local breakout.

Key Metrics: < 18ms (LEO Orbit-to-Ground Roundtrip) | 100 Gbps (Optical Crosslink Throughput) | ±48 kHz (Doppler Shift Compensation) | 99.999% (Orbital Constellation Availability)
