摘要

随着网络的高速发展，网络管理变得越来越复杂，网络管理软件的研究与开发伴随网络的不断发展也越来越受到人们的重视。本文基于SNMP协议、MIB库，详尽阐述了作者设计的TOPOLOGY网管软件的系统设计，以及它的四大模块——网络拓扑发现、网络拓扑生成与布局、查询MIB、功能模块协调与切换的主要设计思想和实现方法，论文中着重研究和讨论了对网络拓扑的发现、生成、布局的设计实现算法。在传统主网拓扑发现算法的基础上，作者提出两种新的补充算法，使得拓扑更加完整，具有一定的创新性。论文所提出的拓扑布局算法采用环型算法与启发式算法相结合，使得布局更加合理，也是该网管软件的特色和创新做法。论文在最后还探讨了对系统进行进一步开发的展望。

Abstract

With rapid development of network, network management becomes more and more complex. Meanwhile, the research and development of network management software are also paid more and more attention to by people. Based on SNMP and MIB, this thesis has accounted in detail for the system design of Network Management Software TOPOLOGY developed by this author. The main designing thoughts and implementation schemes of four modules include network topology discovery, topology generation/layout, MIB polling and modules coordination /switching. The thesis has examined and discussed with focus on the designing and implementing algorithms of network topology discovery, generation and layout.On the basis of traditional backbone network discovery algorithm, the author gives out two new algorithms for supplement to make the topology more complete, and the new algorithms are creative on a certain extent. Topology layout algorithm presented by this thesis combines the elicitation algorithm to the ring algorithm to make the layout more rational and this is also the characteristic and creative way in this network management software. In the end, the prospect of further development to this system is also explored.

Keywords: Topology Discovery, Layout, SNMP, MIB, WinSNMP
