摘要： 针对使用星际链路ISL(intersatellitelinks)的LEO(lowearthorbiting)卫星系统,提出一种基于动态路由策略的网络重构与自恢复算法,通过该算法管理卫星能够尽可能快地检测出故障链路,并通过快速的、自主的测试可精确定位故障链路·重构网络拓扑,当故障链路恢复后,再在拓扑图中恢复该链路·通过在卫星网络上的仿真表明,具有实时性、精确性且可能不占用或只占用很少的额外带宽·

Abstract: A dynamic routing-based reconfiguring and recovering algorithm for LEO satellite systems employing ISL is proposed, by which a designated satellite with management responsibilities is available to check out as soon as possible a ranked list of failed network links and further, detect accurately the failed links through a quick and autonomous testing. Then, it will reconfigure the network topology. After the failed links have been repaired, the satellite with management responsibilities will recover all of them in network topology. The simulation in satellite networks shows that this method has the features of real-time and accuracy especially it will occupy a few bit of extra bandwidth even requires no bandwidth.
