摘 要

隨著網(wǎng)絡(luò)的高速發(fā)展，網(wǎng)絡(luò)管理變得越來越復(fù)雜，網(wǎng)絡(luò)管理軟件的研究與開發(fā)伴隨網(wǎng)絡(luò)的不斷發(fā)展也越來越受到人們的重視。本文基于SNMP協(xié)議、MIB庫，詳盡闡述了作者設(shè)計的TOPOLOGY網(wǎng)管軟件的系統(tǒng)設(shè)計，以及它的四大模塊——網(wǎng)絡(luò)拓撲發(fā)現(xiàn)、網(wǎng)絡(luò)拓撲生成與布局、查詢MIB、功能模塊協(xié)調(diào)與切換的主要設(shè)計思想和實現(xiàn)方法，論文中著重研究和討論了對網(wǎng)絡(luò)拓撲的發(fā)現(xiàn)、生成、布局的設(shè)計實現(xiàn)算法。在傳統(tǒng)主網(wǎng)拓撲發(fā)現(xiàn)算法的基礎(chǔ)上，作者提出兩種新的補充算法，使得拓撲更加完整，具有一定的創(chuàng)新性。論文所提出的拓撲布局算法采用環(huán)型算法與啟發(fā)式算法相結(jié)合，使得布局更加合理，也是該網(wǎng)管軟件的特色和創(chuàng)新做法。論文在最后還探討了對系統(tǒng)進行進一步開發(fā)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
