Autonomous identification based on correlation of faulty links for satellite communication networks

As manual service is often required for identification of faulty links with low accuracy, an approach named dependent failure algorithm was proposed to identify the faulty links in satellite communication networks. By building a faulty link identification graph (FLIG), the management satellite can real-timely and autonomously identify a ranked list of the most probable failed network links. The algorithm was compared with traditional method in the analysis of the sample network. Finally, test results demonstrate the validity and efficiency of the proposed method.
