NTN Protocol: 容迟网络 (DTN)、天基 QUIC 协议演进与卫星高延迟传输优化
NTNProtocol 针对大时延高误码空间通信信道深度重构网络与传输层协议，全面落地 RFC 9171 容迟容断束协议 (Bundle Protocol)、QUIC BBR 智能拥塞控制算法及 SCPS-TP 性能增强代理 (PEP)。

Key Metrics: 100 Gbps+ (星间激光链路带宽) | <25 ms (低轨卫星传播时延) | ±50 kHz (多普勒频移补偿范围) | 99.999% (星座传输服务等级 (SLA))
为何标准地面TCP协议在太空环境中失效
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.
