Research of Trunk Technology Oriented Topology Discovery Algorithm
With the enterprise's network being a large scale and complex,along with VLAN technology getting widely used in data-link layer network,the current topology discovery algorithm has weakness in discovery efficiency and adaptability.This paper analyzes the Trunk technical characteristics combining with address forwarding information and the Trunk network to come up with a new topology discovery algorithm,the algorithm improves the network topology discovery algorithm operating efficiency and accuracy of the results found,In addition,the algorithm analyzing multi-vendor data so that the algorithm will be suit for the current mainstream of multi-VLAN switching network topology and it will give a logical connection information,at the same time,this paper presents the test results of algorithm implementation in a campus network.
