The Research And Practice Of Hierarchical And Distributed Computer Network Management System

With development information construction,the computer network obtains the widely application. In the computer network, the network management system is important to the entire network management, maintenance and network overall performance promotion. This article has researched some provincial military region computer network the present situation and the existence problem and developed a set of network management system which has complete functions. The network management system, which bases on the SNMP (Simple Network Management Protocol), supports Hierarchical and Distributed network management. It has the advanced architecture design, the innovation physical network analysis algorithm discovery technology, the nimble distribution network management technology, the function comprehensive IP address binding technology. And it supports the centralized management and the distribution disposition unifies, deploys many interconnections the network management center, divides the management level. Also each center has a higher authority center and many subordinate centers, and each network management center is responsible to manage the local network and to the subordinate line monitoring. The subordinate center must transmit initiatively the local acquire the important network management information to the higher authority center, the higher authority center can force the setting the data acquisition disposition of subordinate center.In view of the concrete application demand, the paper has deeply researched to the following questions.(1) The provincial military region computer network present situation, the application demand and the existence question have carried on the concrete analysis and the research.(2) Carried on to the computer network management technology development present situation and the practical technology discuss systematically.(3) In view of the present computer network topology special details and the actual use demand, have carried on the system design to the network management system. And carried on to the network system function realization detailed discussed.(4) To some technical difficulty in the system realization process, such as unattended, the illegal main computer early-warning, the Remote shutting down port and so on have carried on the thorough discussion. This article research in the following aspect has yielded the obvious result.(1) The network management system architecture design is advanced and reasonable. The system architecture design has fully used the newest object-oriented technology, the component technology and the database technology; it is composed by a core module and a series of function plug-in unit.(2) To the analysis algorithm discovered technical the algorithm, the article makes the improvement, proposes one brand-new physical network analysis algorithm discovery algorithm. When the HUB between the switch connection or the network load is heavy, it causes certain switch in the information acquisition not entire environment, guaranteed the algorithm can realize smoothly.(3) Through the running, it confirmed that the system is stable and reliable; it has already realized functions which are user demanded, and the entire network each management function (network configuration, performance statistics, fault management, safety control and so on).
