Analysis and Research of Some Network Topology Searching Methods
He Peng, Qiu Jian-lin · Microcomputer Development · 2005
This text is for purpose of helping people to choose suitable network topological searching method under topological requirement and network terms in different network.Through analysing and comparing about the respects,such as level of the network,practical range,topological grain size,etc.,find that each kind of method can't search for all equipment in the network intactly accurately.There are its suitable range,merit and limitation.If can't find the detailed and accurate network information,is only interested in the growth of the network,can select the topological search based on DNS agreement route form for use;And is used for finding that the backbone in the network is topological,reflect the whole state of the network,can select for use and search for topologically on the basis of SNMP agreement network;Supports OSPF agreement to the network equipment and can measure and report the topological some change of network dynamically,can select the network based on OSPF agreement for use to search for topologically.So should combine many kinds of technologies selectively to finish together according to the need in the practical application.
