NTN Protocol: Delay-Tolerant Networking (DTN), QUIC over Space & Satellite Transport Optimization
NTNProtocol optimizes network, transport, and application layer protocols for satellite channels, implementing RFC 9171 Bundle Protocol, QUIC BBR congestion control, and SCPS Performance Enhancing Proxies (PEP).

Central System: Space Transport - RFC 9171 & QUIC
Network Nodes
- Bundle Protocol v7
- QUIC 0-RTT
- BBR v3 Space
- SCPS-TP PEP
- Erasure Coding
Architectural Protocol Layers
- User & Terminal Access Layer (3GPP Rel-17/18 NR-NTN & IoT-NTN): Direct communication from smartphones and IoT sensors to satellites
- Space-Borne Radio Access (gNodeB / Transponder) (Regenerative Digital Payloads & Bent-Pipe Transparent Processing): In-orbit demodulation, digital beamforming, and spectrum channelization
- Inter-Satellite Mesh & Space Transport (Optical Inter-Satellite Links (OISL) & 60 GHz V-Band Cross-Links): Autonomous multi-hop laser packet routing in vacuum at the speed of light
- Ground Teleport & Core Cloud Ingress (High-Throughput Q/V-Band Gateways & Optical Ground Stations): Terabit feeder link downlinks connected directly to cloud hyperscalers
Key Metrics: 100 Gbps+ (Optical Cross-Link Bandwidth) | <25 ms (LEO Propagation Latency) | ±50 kHz (Doppler Shift Compensation) | 99.999% (Constellation Transport SLA)
Why Standard Terrestrial TCP Fails in Space
Core Engineering Areas
- Delay-Tolerant Networking (DTN) — Store-and-forward bundle routing enabling communication across discontinuous orbital passes and deep-space links.
- QUIC & BBR Over Satellite — Replacing legacy TCP with UDP-based QUIC to resist high packet corruption and long round-trip latencies.
- SCPS-TP & PEP Gateways — Transparent proxying at ground stations to spoof TCP ACKs and accelerate throughput over geostationary beams.
