Research Of The Network Topology Structure Data Changes Perception Technology

With the high-speed development and wide application of computer and networkcommunication technology, the internet has penetrated into every field of human activity.More and more enterprises and organizations have established cyber network systemsaccording to their own business needs to improve work efficiency and reduce business cost. Inthe establishment of the network system, monitors in real time and network fault detection ofthe equipments in use, become practical problems in front of managements and technicalpersonnel. Therefore, it is important to study on the sensing technology of the data changes ofnetwork structure.Rely on the manual management traditionally to manage large-scale network system isalmost impossible, so a powerful network management software for the automatedmanagement of network is urgent need. And the network topology information discoveryautomatically and data fault detection is very important in the function of networkmanagement software. SNMP protocol is a industry standard in the field of networkmanagement, it is supported and used widely by many network manufacturers. Based on thepractice of the campus network management and an understanding of the technology ofnetwork topology discovery, this article designs and achieves the sensing technology of thedata changes of campus network structure based on SNMP.This paper mainly studies the key technology of network node (single networkequipment or terminal) data monitoring, including the unique identification of nodeequipment, data changes of node running status, puts forward an recognition technology ofthe heterogeneous network layer topology, identification technology of the link layer topologystructure, and multi-table detection technique of data changes. This research can achievemonitor in real time of the network node running status, help the network administratorstimely find and solve problems.Effective implementation of network node state monitoring not only is advantageous tooptimize cyber source configuration, but also enables network administrators can master the running state of network system in all aspects and irregularities, it has great significance forthe safe and reliable operation of the network system.
