摘要

The development trend of low-earth-orbit (LEO) mega-constellations for internet services is rapidly advancing toward an all-optical network architecture. This shift addresses the critical challenge of limited frequency resources, a major bottleneck in traditional systems, while significantly enhancing the system's capacity and efficiency. To further optimize routing strategies and maximize data exchange throughput within such networks, in this paper, we propose an innovative high-throughput data exchange technology based on optical network coding. This approach effectively doubles the throughput of optical networks in a mega-constellation. Using simulations, we demonstrate the performance improvements achieved by this method. Furthermore, we leverage the regularity, the symmetry, and the predictability inherent in satellite distribution patterns to evaluate hop numbers in the all-optical network. Our analysis focuses on minimizing the inter-satellite forwarding hops to enhance routing efficiency. These findings offer valuable insights for designing scalable and efficient routing strategies, which are essential for the next generation of LEO mega-constellation networks.
