Abstract

Aimed at the shortages of traditional large-scale network topology discovery model in network performance, integrity and real-time performance, when acquiring topology information. According to the characteristics of easy expansion and fast convergence with OSPF protocol, a network topology discovery model OTDM is proposed, based on OSPF. The model adopts passive monitoring to obtain network topology information. After obtaining the link state update (LSU) packet in the OSPF protocol, the Router LSA and Network LSA is analysed to obtain the regional network topology. Then Summary Network LSA is analysed, obtained through boundary routing, to obtain the inter-regional network topology. So a complete network topology is obtained. The experimental results show that the model can accurately and completely acquire large-scale network topology, which can make up for the shortages of existing large-scale network topology discovery technology.
