航母打击群（CSG）的通信必须维持跨异构链路的任务流量，这些链路的质量随距离、天气、衰落和间歇性中断而变化。我们提出了一种集成的软件定义网络（SDN）/软件定义无线电（SDR）框架，该框架在单一控制平面下统一了5G和卫星通信（SATCOM），用于CSG通信中的双路径故障切换。该框架通过随机模拟在四个作战区域进行评估：诺福克、挪威海、菲律宾海和北太平洋风暴路径。该框架将集中式SDN控制器与采用自适应调制编码（AMC）的莱斯衰落5G信道、具有ITU-R P.618/P.838雨衰的Ku波段卫星通信信道以及两条链路上的Gilbert-Elliott突发可用性过程相结合。控制器根据流量类别和当前链路状态路由每个数据包。实验使用每个参数设置下50,000个数据包的60次独立试验，采用公共随机数、配对置信区间以及跨故障、衰落和区域扫描的收敛性诊断。对于诺福克天气基线，SDN路由达到93.09%的可靠性，而5G单独为36.22%，卫星通信单独为89.87%，配对增益分别为+56.87和+3.22个百分点。在联合低莱斯K因子/高突发故障压力下，优势进一步增大，并且随着信号与干扰加噪声比的降低，AMC提高了5G的鲁棒性。在所有四个区域中，SDN仍然是可靠性最高的模式，这表明跨层SDN控制的故障切换在不依赖确定性链路抽象的情况下提高了海事弹性。
英文摘要
Carrier Strike Group (CSG) communications must sustain mission traffic across heterogeneous links whose quality varies with distance, weather, fading, and intermittent outages. We present an integrated Software-Defined Networking (SDN)/Software-Defined Radio (SDR) framework that unifies 5G and satellite communications (SATCOM) under a single control plane for dual-path failover in CSG communications. The framework is evaluated via stochastic simulation across four operational regions: Norfolk, the Norwegian Sea, the Philippine Sea, and the North Pacific storm track. The framework couples a centralized SDN controller with a Rician-faded 5G channel under Adaptive Modulation and Coding (AMC), a Ku-band SATCOM channel with ITU-R P.618/P.838 rain attenuation, and Gilbert-Elliott burst-availability processes on both links. The controller routes each packet by traffic class and current link state. Experiments use 60 independent trials of 50,000 packets per parameter setting with common random numbers, paired confidence intervals, and convergence diagnostics across fault, fading, and region sweeps. For the Norfolk weather baseline, SDN routing reaches 93.09% reliability versus 36.22% (5G-only) and 89.87% (SATCOM-only), with paired gains of +56.87 and +3.22 percentage points. The advantage grows under joint low-Rician-K/high-burst-fault stress, and AMC improves 5G robustness as Signal-to-Interference-plus-Noise Ratio degrades. SDN remains the highest-reliability mode across all four regions, indicating that cross-layer SDN-controlled failover improves maritime resilience without relying on deterministic link abstractions.
