Abstract

In recent years, there has been a global surge in research, development, and deployment of satellite internet, leading to the rapid advancement of low-Earth orbit satellite communication constellations. To meet the growing demands of satellite communications, these constellations have incorporated inter-satellite laser links to enhance communication capacity. This paper explores the single-wavelength all-optical satellite network architecture, with a particular focus on addressing congestion issues in such networks. Correspondingly, it proposes path planning algorithms and strategies to effectively mitigate these challenges.
