Researchers have developed a new software-defined networking (SDN) framework to manage the immense scale of Low Earth Orbit (LEO) satellite mega-constellations. This approach utilizes graph neural networks (GNNs) to model the complex topology and Koopman theory to linearize system dynamics. A Graph Koopman Autoencoder (GKAE) predicts behavior within orbital shells, enabling coordinated control by a central SDN controller. Simulations on the Starlink constellation showed significant improvements in spatial compression and temporal forecasting with a smaller model footprint. AI
