卫星网络不仅能提供全球无缝覆盖,具有连续的高带宽性能,而且还支持灵活、可扩展的网络配置。文中阐述了具有星间链路的卫星网络在空间通信中的重要地位及其路由算法应当具有通用、简洁和可靠等特点。从单层、两层与多层卫星网络路由三方面综述了多种路由算法,并对其进行详细的分析和比较,最后指明了进一步的研究方向。
Satellite networks not only provide seamless global coverage, with continuous high-bandwidth performance, but also support flexible and scalable network configuration. The article expounds the important position of the satellite network with inter-satellite link in space communication and its routing algorithm should be universal, concise and reliable. A variety of routing algorithms are reviewed from three aspects of single-layer, two-layer and multi-layer satellite network routing. The routing algorithms are analyzed and compared in detail, and finally the further research directions are pointed out.
