OISLMesh | 空间星间全光网状激光动态路由与大规模巨型星座拓扑自主控制

OISLMesh 在动态轨道星座中实现分布式数据包路由，每颗卫星配置 4 组光通信终端，在跨越极区接缝时执行亚毫秒级路径重算。

OISLMesh 4-Head Orbital Grid Routing Topology

Simultaneous intra-plane and inter-plane laser links with autonomous polar seam switching

Central System: Intra-Plane Forward Satellite - Constant distance optical link (+1 in plane)

Network Nodes

Intra-Plane Forward Satellite
Intra-Plane Aft Satellite
Inter-Plane Left Crosslink
Onboard L3 Space Router

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)

星间激光网状路由、动态轨道拓扑与在轨数据包交换

Core Engineering Areas

Segment Routing IPv6 (SRv6) in Space — Source-routed packet headers directing multi-hop orbital traffic along deterministic low-latency great-circle paths.
Polar Seam Dynamic Link Management — Managing high-speed counter-rotating satellite passes at orbit intersections without dropping inter-orbital packet flows.
Disruption-Tolerant Networking (DTN) Fallback — Bundle Protocol (RFC 9171) storage and forward buffers ensuring zero packet loss during temporary solar conjunction blinds.
