The Design And Implementation Of Web-based Network Management System

With the rapid development of the computer network in the changing IT world, network management is becoming more complicated. There are many reasons for it, but the following two are the most important facets: the first is that so many different devices are invented; the second is that many new protocols are issued. The research of the network management system then becomes a hotspot with the developing of the network. We do research the network management system to manage the system validly and mark out the schema of the network for the future wisely. And I choose the theme Web-based network configuration management as my task, to apply the automatic ability to reality and improve the performance of the system.In this paper, After introducing the current situation of the network management and the basic management technology, we give the instance of the realization of the network topology management module in the network configuration system, and I present the communication model, interface definition, data structure and concrete algorithms; We provide the another part of the network configuration: inventory management, which help the function of the management a lot; To improve the performance of the server, we analyze a lot of synchronization technology and multithreaded skill, and at the end we implement the Overlapped I/O technology to guarantee the efficiency of the network communication in the server, which is most effective way in the Windows platform; As compatibility, extensibility and reusability are concerned, we adopt the technology of the J2EE: RMI(Remote Method Invocation) and JNI(Java Native Interface), to follow the current development the network with Web-based ability, and we describe the Web-based network management as a whole and primary flow diagram in detail; Because the lower version of the SNMP protocols are not in security, SNMPv3(USM and VACM) is adopted to amend it, but most of network devices don't support this character, so this part is only in experiment just in our system environment (like Computer Center of); another important part is: we innovatively apply the artificial intelligence technology (Rule-based Reasoning, Case-based Reasoning) and vague reasoning matching technology to the network management which greatly improve the efficiency of the performance and simplify the operation. At last, we give a summarization and present the prospect.
