摘 要

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
