Research Of Computer Network Automatic Topology Discovery Technology

The network topology display is an important functional component in the network management. It provides the means of understanding the general structure of the network. Directing towards the requirement of topology management in the campus networks, the paper mainly researches into the network management protocol and relative technologies and the algorithms of network topological discovery, designs and implements a algorithms of network topological discovery which combines SNMP, ARP with ICMP. It introduces the way of the topological map displaying in the paper at the same time. The paper also researches into the multiplayer network topological discovery and the implementing theory of the virtual network topological discovery, discussing the technology of network fault localization based on the fault tree at last.
