XhaulCore Disaggregated 5G/6G Non-Terrestrial Core Architecture

Kubernetes-orchestrated control plane and FPGA-accelerated onboard user plane

Central System: Terrestrial 5GC Control Plane - AMF, SMF, and UDM microservices on high-assurance kubernetes

Network Nodes

Terrestrial 5GC Control Plane
Onboard Lightweight UPF
Cryptographic N3/N4 Transport
Terrestrial Breakout Gateway

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)
