Integrated, J2ee-based Nms Resources

The rapid growth of computer network scale and network structure complexity makes traditional network management method more and more difficult to meet the requirement of computer network development. Distributed network management system effectively solved the problem by reasonably distributing the network management functionality to whole network.This article firstly discusses core technologies of J2EE, the functionalities and mechanisms of these core technologies, and the distributed system development platform that can be constructed by these technologies. It then analyzes the requirements of current network development to network management system technologies, and how J2EE, especially distributed application program model of its EJB component structure, can meet the requirements. Finally it explores a structure that could be constructed by J2EE distributed network management system. The structure consists of components implemented by EJB technology. These components are very flexible in their structures and distribution. Each management component supports RMI, SOAP protocol and provides good interoperability. The structure or system will have good extensibility and compatibility when the public interfaces of components are standardized. In this structure, each component is distributed in whole network independently and also can be integrated easily and effectively.
