LEOCraft: Towards Designing Performant LEO Networks
summary
LEOCraft is a modular, flow‑level LEO network simulator and visualization that computes throughput, coverage, latency and hop counts and renders topology changes at nanosecond granularity. It scales to 83K satellites and 1K ground stations, uses domain‑aware heuristics to cut the search space, and optimizes constellation design about 5× faster than black‑box methods. The authors evaluate four optimizers and find variable neighborhood search consistently best, validate findings across traffic matrices, and publish code on GitHub.
