The Analyse And Design Of The Network Monitor And Control System For Dazhong Net

Along with networking's flourishing more and more daily, people pay more and more attention to the network management question. Dazhong Net existing technology has only done the foundation network construction, but has the a lack of efficiency and accuracy to the entire Dazhong Net network data management and has the breakdown strain capacity facing status problem.This paper's goal is: develop the Dazhong Net network monitor and control system to enable its technical department has the keen failure detection ability and effective supervision to the Dazhong Net's equipment and the network, raise the static and dynamic management ability, realizes the comprehensive monitoring.Through needs analysis, we got a good understanding of customer needs, the paper carried out a general description for resource management module, proxy module, proxy management module, event processing module, client management module and other functions module. On this basis, the paper proposed a network monitoring system architecture and model framework, and carry out a detailed analysis and discussion for some of the representative of the module.This system's key technologies including information collection, proxy management and interfaces processing . Information collection is done by resource management module, including classified information, input information, change information, and the visiting management for information. The upper module can make failure and performance management based on this module. Between the processing level and collection level, we add agents system in order to complete the optimized acquisition for uploading information. A reasonable division of the module and clear interface make it easier for the system to maintain and upgrade. Complete the flow of information. As the interface we emphasize: when faced with a different interface, the interface need to support a variety of communication protocols, and, make data interface format criterion.By using role-based access control strategy and the way of web, the system can realize interact with user.To sum up, in this paper, on the basis of the actual needs of customers and business processes, complete the design and implementation of network monitoring systems, and test the system. The current system has been used in Dazhong Net network management system, running for six months time, affirmed by the customers.
