OISLMesh | Intersatellite Optical Laser Mesh Routing & Dynamic Constellation Topology

OISLMesh implements decentralized packet routing across dynamic orbital constellations—maintaining four-head optical crosslinks per spacecraft and executing sub-millisecond route recalculation as satellites cross polar seams.

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)

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.
