基于关联性的卫星通信网链路故障自主识别

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

针对传统的网络链路故障识别方法往往需要人工参与、准确性有限的不足,提出了一种网络元素关联性的卫星通信网链路故障自主识别算法.该方法通过建立卫星网故障链路识别模型(FLIG),管理节点能够自主地、实时地检测出最可能出现故障的链路.利用该算法对示例网络链路故障进行了分析,并且与经典的非关联性的故障识别方法进行了对比.实验结果表明:所提出的算法考虑网络元素故障之间的作用,结果精确并具有实时性.

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.
