Topology Semantic Routing for Mega-Constellations

Unlike terrestrial networks with almost-static topologies, megaconstellations - consisting of thousands of Low Earth Orbit (LEO) or Medium Earth Orbit (MEO) satellites - form dynamic, grid-like topologies that change predictably and very frequently. The number of topological changes is further increased by the frequentestablishment or termination of links to ground stations and due to atmospheric effects (weather) that affect feeder links. These characteristics make mega-constellations significantly different from other networks, requiring new routing strategies.
