摘要
为了解决集中式网络故障管理固有的缺陷 ,提出了一种基于 SNMP网络管理环境、使用分布式智能代理进行网络设备告警关联的算法 .算法分成 3步 :1智能代理驻留在设备本地 ,对设备发出的告警进行分类 ,作为相应协议对象的故障模型 FSM的输入 ,运行这个 FSM以产生该协议对象的当前状态 ;2按照关联关系的形式化定义 ,尝试对状态不正常的协议对象进行关联 ;3为了给关联的结果增加一个可信度的度量 ,计算关联结果的信念 ,将关联的结果及其信念报告给网络管理平台 .该算法将告警关联和故障标识的难度进行了分解 。
In order to avoid the intrinsic drawbacks of the centralized fault management in a computer network or a communication network, an alarm correlation algorithm using distributed intelligent agents in a SNMP network management environment is proposed in this paper. The algorithm can be divided into three steps. (1) The intelligent agent resides on a network device. Once it receives an alarm emitted by the device, it classifies the alarm according to its meaning and its severity level, and then inputs the result to a finite state machine (FSM) of the fault model of a certain protocol object. Next, it runs the FSM in order to establish the current state of the protocol object. (2) Using the formal definition of a correlation relation, the intelligent agent tries to correlate the protocol objects whose current states are abnormal. (3) In order to add a reliability measurement to the correlation result, the intelligent agent computes a belief of the correlation result protocol object, and then reports the object and its belief to a network manager. This algorithm decomposes the complexity of the alarm correlation and fault identification, so it is of great benefit to realize real time and automated network management.
