Abstract: The article puts forward a fast discovery algorithm for network topology based on OSPF to aim at the existing problems in the network topology discovery system. Then it discusses the algorithm of adding, modifying topology information and drawing topology map, and analyses the performance and characteristic of this algorithm. It also discusses the technology of fast displaying topology information with graph and the key techniques to implement the display system. The experimental result shows that the new system has the features of fast discovering the topology and good displaying effects compared with the similar system in the WAN environment.
