SpaceMeshNetwork: 자율 레이저 메시 라우팅 및 궤도 패킷 스위칭 시스템

SpaceMeshNetwork는 자율 위성 간 레이저 메시 라우팅 프로토콜을 표준화하여 고속 저궤도 콘스텔레이션에서 멀티홉 광 패킷 전송을 지원합니다.

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)
