Abstract
A redundancy switching optimization method based on network flow algorithm is pro-posed to solve the inefficient problem of traditional manual enumeration for the optimal redundancy switching solution of communication satellite transponders.First, amplifiers, switches and channels are represented by nodes,RF cables are represented by edges,and the net-work model of the redundancy ring is found based on its topology.Then,an increasing flow is constructed by Busacker-Gowan arithmetic until the Minimum Cost Maximum Flow of the net-work is found.Finally,the optimal redundancy switching solution is derived from the Minimum Cost Maximum Flow.The method can be used to find the optimal initial configuration and the optimal restoration configuration.Simulation results show that the method can accurately and promptly find the optimal configuration,and can be used in transponder design to improve effi-ciency.关键词
