【摘要】 随着计算机网络的蓬勃发展,网络在各方面的应用也越来越广泛,用户对网络的依赖越来越大,网络的稳定性、可靠性和安全性成为了维护网络的重要问题。高质量的网络管理就成为了现在网络技术中的重要研究课题。网络拓扑是网络中各个节点之间连接关系的表现,是网络管理系统高效运行的基础。因此,我们就需要一种更为有效的方法来实现网络拓扑发现。本文以高校校园网为研究背景;详细介绍了SNMP协议的基本概念及工作原理;并针对几种常用的网络拓扑发现方法进行分析,提出了本课题背景适用的拓扑发现方法;以此为基础,研究、实现了以三层交换机为主的主干网络拓扑的自动发现,提出了一个新的算法实现链路层网络的自动发现,讨论分析了哑设备发现理论。系统完成后在某高校校园网中试运行,稳定可靠,效果良好,达到了预定目标。更多还原

【Abstract】 The rapid development and widespread application of net technology makes it urgent for increasing number of net-users to pay great attention to the safety, stability and credibility of net. Thus, the net management with high quality is attached great importance to by researchers. As the relation between nodes , Topology is the base of the operation with high efficiency of net management system, which urges us to find a more effective way to discover the net topology.This article introduces the basic concept and working principle of SNMP backed on university campus net and puts forward the proper topology discovery for the research which enables to realize the auto-discovery of backbone topology with three switchboards, to propose a new algorithm for auto-discovery of link level operation and to analyze the dumb-device discovery.The system was operated at campus net of Anhui Institute of Architecture & Industry and performed well as it was designed.更多还原
