Nowadays network fault management systems are developing in the direction of automation and intellectualization. In order to improve the intelligent level of the traditional network fault management system, an intelligent network fault management system is designed based on the expert system rule engine Jess and SNMP protocol. The system can monitor network devices in real-time, and diagnose network faults in the independent mode or the network administrators interactive mode. If the result of the fault diagnosis indicates that the fault can be recovered by the system automatically, the system will ask the network administrators whether the fault should be automatically recovered by the fault recovery module or not. The paper finally discusses the system development environment and key development technologies. Based on the expert system technology, the system can significantly improve the ability and efficiency of network fault management.%当前网络故障管理系统正朝着自动化智能化的方向发展.为了提高传统网络故障管理系统的智能化水平,基于专家系统规则引擎Jess和SNMP协议,设计了一个智能网络故障管理系统.该系统可实时监控被管网络设备,采用独立模式或者与网管人员交互模式进行故障推理诊断;若故障诊断结果表明某故障可由系统自动排除,则询问网管人员是否利用故障恢复模块自动排除.文章最后探讨了系统开发使用的开发环境与关键技术.由于采用了专家系统技术,该系统能够显著提高网络故障管理能力和效率.
