网络管理中的一种分级告警关联方法

A Hierarchical Alarm Correlation Method in Network Management

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单个网络设备告警关联的算法 .算法分成三步 :①智能代理驻留在设备本地 ,对设备发出的告警进行分类 ,作为协议故障模型有限状态机的输入 ,产生TCP/IP协议实体的当前状态 ;②按照服务关系 ,将状态不正常的协议实体关联起来 ;③对关联的结果赋予一个信念 ,报告给网络管理中心 .该算法将告警关联和故障标识的难度进行了分解 。

An alarm correlation algorithm using distributed intelligent agents in a SNMP network management environment is proposed. The algorithm can be divided into three steps: (1) classify the alarms emitted by a network device, and input the results to the simple finite state machines (FSM) of TCP/IP protocol entities in order to establish the next state of the entities. (2) using serving relations, correlate the protocol entities whose current states are abnormal. (3) add a belief to the correlation result and then report it to the network management center. This algorithm is of great benefit to realize real time and automated network management.
