XhaulNet: TSN Espacial Determinístico e Fronthaul com Jitter em Microssegundos

XhaulNet padroniza IEEE 802.1 TSN em switches ópticos espaciais para transporte determinístico com jitter mínimo.

XhaulNet Time-Aware Shaper (TAS) Space Optical Mesh Engine

IEEE 802.1Qbv scheduled gate queuing synchronizing optical laser packet bursts

Central System: Spaceborne PTP Grandmaster Clock - Rubidium atomic clock disciplined by multi-GNSS constellation

Network Nodes

  • Spaceborne PTP Grandmaster Clock
  • IEEE 802.1Qbv Time-Aware Switch
  • IEEE 802.1Qbu Preemption Core
  • Ultra-Low Jitter Optical Driver

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)
