一体化融合网络仿真平台数据集

本项目通过设计一种参数化的巨型星座网络描述方法，并基于上述描述开展网络性能预测和评估方法，能够基于不同的星座设计，网络策略等信息，计算出对应的网络性能（如延迟，吞吐量等指标）。包括 Starlink、OneWeb与Telesat对于不同人口密度区域的覆盖率、在不同维度与经度带上，每百万人口可用的Starlink、OneWeb与Telesat卫星数量、不同区域（北京、纽约、伦敦、悉尼）之间通过Starlink、OneWeb与Telesat通信的端到端延迟、不同区域（北京、纽约、伦敦、悉尼）之间通过Starlink、OneWeb与Telesat通信的带宽、Starlink、OneWeb与Telesat中各个卫星节点相对于整个星座结构的介中心性和不同区域（北京、纽约、悉尼）之间基于地面云节点的低延迟中继选择算法和天地协作的低延迟中继选择算法的端到端时延。This project proposes a parametric description method for large-scale satellite constellation networks, and develops network performance prediction and evaluation methodologies based on this framework. It can compute targeted network performance metrics (including latency, throughput, etc.) using inputs such as distinct constellation designs and network policies. The supported calculation contents are listed as follows: 1. Coverage rates of Starlink, OneWeb and Telesat over regions with different population densities; 2. Quantity of available Starlink, OneWeb and Telesat satellites per million population across various latitudes and longitude bands; 3. End-to-end communication latencies between four representative regions (Beijing, New York, London, Sydney) via Starlink, OneWeb and Telesat; 4. Communication bandwidths between the four aforementioned regions via Starlink, OneWeb and Telesat; 5. Betweenness centrality of each satellite node in Starlink, OneWeb and Telesat relative to the full constellation structure; 6. End-to-end latencies of two types of low-latency relay selection algorithms for communications between three regions (Beijing, New York, Sydney): one based on ground cloud nodes, and the other adopting space-ground collaborative design.
