Based On J2ee Technology Research And Development Of The Nms

The scale of computer network is becoming larger and the complexity increases greatly, one network consists of several subnets, which includes many network system platforms and the devices provided by various manufacturers. All these factors bring a great challenge to the network management administrator. As the customers demand more and more on QoS of network, large network service providers require reliable network management system with high performance to manage network effectively, which enable them to provide customers with high quality services and strengthen themselves in the competition.Network management is a very important technology in computer network, it includes performance management, configuration management, fault management, accounting management and security management. Network management system must manage effectively the various computer systems, various network devices that using different protocols, and have complete network management functionalities and high usability, providing network service provider with methods of network management and decision-making. So, network management system has high theoretic, social and economic signification.The need in network management market is quite large, but almost all of current systems are insufficient. As Network Management Systems are large and distributed software systems, the current systems are suffering from the scalability and flexibility issues common in today's technology. Fortunately, Java and J2EE technology offers a possibility to find a solution to these problems. This paper will present the design of network management system using Java and J2EE technology, and discuss the solution of the certain problems.This paper firstly introduces some basic theory about network management, includes basic knowledge of network management, five functionalities of network management and the architecture of network management. Secondly, the paper analysis several network management protocol just like SNMP, TR-069 and SGMP. And then, the paper discusses the advantage and disadvantage of J2EE technology apply in the network management, and addresses two technologies of EJB and JMX in J2EE architecture. Finally, based on J2EE, we provide the total design of this network management system, and describers the details of the implementation and give some advice.
