Abstract

The Satellite network is an important part of the global network. However, the complex architecture, changeable constellation topology, and frequent inter-satellite connection switching problems bring great challenges to the routing designs of satellite networks, making the study of the routing methods in satellite networks a research hotspot. Therefore, this paper investigates the latest existing routing works to tackle the dynamic routing problems in satellite networks. The architecture and development of satellite networks are presented and analyzed first. Afterward, dynamic routing problems in satellite networks are analyzed in detail based on the time-varying network topology. According to the latest works, the advanced satellite network routing schemes, including single-layer and multi-layer dynamic routing are introduced and analyzed. In addition, the merits, shortcomings, and applications of these schemes are analyzed and summarized. Finally, potential technologies and future directions are discussed.

摘要

卫星网络是全球网络的重要组成部分。然而，其复杂的架构、多变的星座拓扑结构以及频繁的星间连接切换问题给卫星网络的路由设计带来了巨大挑战，使得卫星网络路由方法的研究成为一个研究热点。因此，本文研究了现有的最新路由工作，以解决卫星网络中的动态路由问题。首先介绍并分析了卫星网络的架构和发展。随后，基于时变网络拓扑详细分析了卫星网络中的动态路由问题。根据最新工作，介绍并分析了先进的卫星网络路由方案，包括单层和多层动态路由。此外，对这些方案的优缺点及应用进行了分析和总结。最后，讨论了潜在技术和未来发展方向。
