【摘要】 分析了网络中故障的传播原理,在此基础上提出了一种使用移动代理的三层网络故障管理体系,对网络故障管理中关联问题的难度进行了有效的分解。根据网络故障管理体系的要求设计了不同功能的移动代理,及该体系下它们的工作交互过程。该体系充分利用了现有网络条件,满足了现代网管对于故障管理的及时性、自学习性的要求,减轻了网络负载。此外,按照这种方法建立起来的网络故障管理系统具有一定的通用性和灵活性,能够适应不同的网络和网络的变化,最后通过实验证明了系统的部分优越性。更多还原

【Abstract】 This paper analysed the propagation process of network faults, applied with mobile agent(MA) in network fault management, proposed a three-layers network fault correlation system and decomposed the difficulty of network fault correlation problem effectively. Then the paper designed different MAs to satisfy the system, and the MAs ’ cooperation in the system. The system made full use of current network conditions to match the timeliness and self-study demands of fault management, and reduced the network load. Otherwise, the network fault management system in this method was general enough to be used in different networks, and adaptable to the evolvement of a network. Finally, through experiment, the paper proved some superiority of the system.更多还原
