新型网络管理系统模型及其专家系统

A Novel Network Management System Model and Its Expert Systems

现代计算机网络管理是一项复杂而又繁重的工作，它需要大量的信息并运用操作者的判断与技能．由于产品厂商不同而导致的异种网络环境以及高质量的用户服务需求，这种网络管理的复杂性还在不断增加．文章提出了一个进行网络智能管理（ｉｎｔｅｌｉｇｅｎｔｍａｎａｇｅｍｅｎｔｏｆｎｅｔｗｏｒｋ，简称ＩＭＮ）的新型系统模型．在ＩＭＮ体系结构中，用专家系统处理特定问题，建立一个智能故障管理系统；用网段或网域中的智能代理建立网络管理与应用和用户需求的密切关系；给出了一个管理员模型，用于控制各子系统，协调各项管理任务．

The management of modern computer networks is a complex and labourintensive task that requires the assimilation of vast amounts of information and application of operator's judgment and expertise. The complexity is further increased because of the multivendor heterogeneous elements that make up many of these networks, and the high quality of user service requirements. In this paper, the authors give a novel system model for building an intelligent management of network (IMN) in order to solve related problems. In the IMN architecture proposed, expert systems are integrated in the network management system to handle particularly difficult problems, especially an intelligent fault management system is presented. By spreading intelligent agents through network segments or domain, the IMN system can bring the management closer to application and user requirements. The authors also give a manager model in the IMN system, which controls each subsystems and coordinates different management task. The IMN system is well suited to manage the current computer network intelligently, effectively and efficiently.
