【摘要】 在光传送网(OTN)中的任何故障均会造成网络服务质量的降低,如已经建立的连接突然中断或传输质量下降等.在OTN的基础上,作者研究了故障定位算法,并考虑了网络发生单个和多个故障情况下的故障定位问题,基于已有的二进制树算法提出了改进的思路,采用四叉树的方法,提高了故障定位的效率,进而提高了整个网络的有效性和可靠性.更多还原

【Abstract】 Any fault in OTN can results in the decrease of network service of quality,such as the established connection are suddenly interrupted;or degrade the quality of transmission.This paper researched the algorithm of localizing failures based on OTN,and considered single fault and multi faults.Based on the existing binary tree algorithm was put forward on the basis of improving ideas,we adopt the quadtree method and improve the efficiency of the fault location,so as to improve the efficiency and reliability of the whole network.更多还原
