摘　　要：卫星网络正在从单星向成星座、连星座、融星座等方向发展,各类异构星座通过聚合形成巨型星座以发挥卫星网络体系能力。当前互联网应用模式与体验深入人心,巨型星座尽管可借鉴地面、单星、星座现有的相关成果,但是由于其场景极其复杂,因此还需解决多场景下的许多关键问题。本文通过梳理地面互联网和卫星通信网IP化演进过程,对地面IP技术体系发展路线和卫星IP增强技术研究路线进行了详细分析,借鉴地面互联网和卫星通信网IP化成果,提出了巨型星座典型融合互联场景下的异构IP路由交换体制和在轨IP增强与适配的解决思路,通过构建仿真场景,验证了跨星座智能TCP与巨型星座跨域路由技术方案的可行性与优越性能,为巨型星座下一步的理论研究与星座构建奠定了基础。Satellite networks evolves from single satellites to constellations,interconnected constellations,and integrated constellations.Various heterogeneous constellation aggregate into giant constellations,demonstrating the capabilities of satellite network architecture.The application and experiences of the Internet are widely used and valued.Therefore,it's worthwhile to study how giant constellations can achieve the desired IP-based functionality.Although the giant constellation can draw on results from the ground,single satellites,and single constellations,its application scenarios of giant constellations are extremely complex,thus requiring solutions to numerous key issues across multiple scenarios.This paper reviews evolution of IP technologies in ground Internet and satellite communication networks,and provides a detailed analysis of the development path of ground IP technology and the research path of enhanced satellite IP technologies.Drawing on the advancements of IP-related ground Internet and satellite communication networks,the paper proposes a heterogeneous IP routing and switching mechanisms for typical scenarios in giant constellations'integration and interconnection for in-orbit IP enhancements and adaptations.Through constructing simulation scenarios,the feasibility and superior performance of cross-constellation intelligent TCP and giant constellation cross-domain routing technology schemes are validated,laying the foundation for further theoretical research and constellation construction of giant constellations.
