A Topology Searching on Dual-plane Redundancy Network with Multiple Threading Method

To make a solution of the TOPO search in IP network running, the topology foundation and the searching algorithm are studied firstly, on the basis of biplane and redundancy structure of IP network, the multiple threading are adopted. Address table, routing table, ARP table and forwarding information are obtained by node detecting invoked with sub threading. The ARP and external interface of subnet are drawn, the connected equipment and connection information are acquired. The function, flow of topology search and redundancy path detection are designed. In the dual-star network with 198 devices, the instance data shows correctness is up to 100 percent and search time is less than 2 minutes, which meets the actual needs.
