项目摘要

Computer networks expand in a very fast pace in recent year with diversity. How to manage the network for users becomes and important problem. In this research, we focus on the network fault management system. The target of this research is to search for the proper method of management information collection and develop a basic system of network fault management.By the two years research and development, we proposed a new method of information collection for management system. By controlling management traffic in considering of the bandwidth and congestion of network this method can be used on any networks with different speed. We also proposed the idea of synchronization called Snapshot for obtaining high quality network management information. By using this idea, not only the synchronized management can be obtained easily on a SNMP (Simple Network Management Protocol) platform, but also the processing time is reduced.By making use of this two idea, we developed a prototype of fault management system. In this system, we proposed divide and conquer algorithm for detecting faults occcurred in network. This algorithm used event-driven, dynamic symptom isolation method. We have evaluated the performance of this proposed algorithm and have examined the effect of the various operational parameters on two different kinds of networks. In comparison with the conventional system, the system with divide and conquer mechanism improved the performance significantly and at the same time reduced management cost. We consider that the purpose of this research have been achieved.

计算机网络近年来发展迅速且多样化。如何对用户进行网络管理成为一个重要的问题。在本研究中，我们重点关注网络故障管理系统。本研究的目的是寻找合适的管理信息采集方法，开发一个网络故障管理的基本系统。经过两年的研究和开发，我们提出了一种新的管理系统信息采集方法。通过考虑网络的带宽和拥塞来控制管理流量，该方法可以在任何不同速度的网络上使用。我们还提出了称为快照的同步思想，以获取高质量的网络管理信息。利用这种思想，不仅可以在SNMP（简单网络管理协议）平台上轻松实现同步管理，而且减少了处理时间。利用这两种思想，我们开发了故障管理系统的原型。在该系统中，我们提出了分治算法来检测网络中发生的故障。该算法采用事件驱动、动态症状隔离方法。我们评估了该算法的性能，并检查了各种操作参数对两种不同类型网络的影响。与传统系统相比，采用分治机制的系统显着提高了性能，同时降低了管理成本。我们认为本研究的目的已经达到。
