【摘要】 传统的网络链路故障诊断方法往往需要人工参与,而且准确性不高.针对这种情况,提出一种通信网的链路故障自主诊断方法.若已知网络管理节点能够与哪些节点通信、与哪些节点不能通信的路径信息,通过建立诊断模型和概率计算,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范围,并通过定位过程的快速测试精确定位故障链路.仿真实验表明,该方法具有实时性、精确性,且可能不占用或只占用很少的额外带宽更多还原

【Abstract】 Conventionally the manual service is often required for fault diagnosis of network links with improper accuracy brought in.So,a full automatic fault diagnosis approach for communication links is proposed as follows.If the path information that which nodes are available or unavailable to communicate with the node(s) taking charge of network management has both been known,a fault diagnosis model is developed in combination with probability computation,by which the node(s) in charge of network management can implement full automatically the real-time identification of the range where the link failures happen most probably.Then,the link failures can be positioned accurately via quick tests.The simulation results showed that this approach is real-time,highly accurate and full automatic with no or few extra bandwidth occupied.更多还原
