[Abstract]:In the face of the expanding network scale, the increasingly complex network structure and the complex network equipment, the current network monitoring methods can not meet the needs of the current network security management. Real-time dynamic monitoring of network topology nodes and timely and comprehensive understanding of the whole network changes have important practical significance for the safe and stable operation of the network system. From the view of network supervision, this paper puts forward a distributed network supervision model under large scale complex network. The collection, fusion and storage interaction of network topology data are deeply analyzed, and the corresponding data model is proposed. Based on this, a distributed network topology node data monitoring system is designed. And carried on the important link development and the test. This paper starts with the analysis of network monitoring and data management technology such as SNMP, network topology model, topology data fusion and data storage technology, and focuses on the key technologies of distributed network topology node data management monitoring. On the basis of these technologies, a distributed network topology monitoring model is designed according to the current network features and management requirements. Under this framework, the network topology monitoring multi-agent model, the distributed monitoring multi-level multi-domain network, the network node information collected by multi-thread scanning and the TRAP alarm information are designed and studied. The unique identification of topology data and the algorithm of space and time fusion are studied from all aspects of topology monitoring, and the corresponding improvement is put forward in view of the shortcomings of the algorithm. Then, the design of encapsulation format based on XML data is completed. Network topology data interaction and topology data dynamic refresh and other key work. Finally, the system engineering deployment scheme is given in combination with the objective practical requirements. Based on the above research, this paper develops and implements a distributed network topology node data monitoring system, and deploys and tests it in a real network environment combined with specific management tasks. The test results show that the function and performance of the system can meet the needs of practical network security management.
