摘　　要：文中分析了当前主流网管系统在体系结构上的缺陷 ,阐述了分布对象技术 (CORBA)与移动智能体技术各自在网管领域的应用方法与优势 .结合这些优势 ,给出了一个基于 CORBA和移动智能体的分布式网管集成框架 ,并进一步通过实验模拟证实了其可行性 .The increasing scale and complexity of the network are making network management more and more important. The wide used network management systems based on SNMP or CMIP adopt a Client/Server paradigm and are characterized by centralization. Due to the simplicity of the manager/agent model, these traditional systems are widely used. But there are also many drawbacks coming with the simplicity and centralization. Analyzing the limitations of the traditional network management systems, the paper describes the benefits of using CORBA and Mobile Agent technology in this field. Common Object Request Broker Architecture (CORBA) comes from OMG for distributed object process and integration. With the distributed object platform ORB, interface definition language IDL, and the abundant common services of CORBA, an open network management system can be constructed easily. The architecture based on CORBA presented in this paper mainly addresses the integratebility, extensibility, reusability, and scalability of distributed network management. It benefits from the large amount of SNMP/CMIP devices and the mature management platform. At the same time, it provides not only an extensible application framework to process all kinds of changes quickly through CORBA's distributed object model, but also the independence of programming language though IDL. And it also does well in information sharing and interoperation between high level services. A mobile agent is an active computing entity characterized by the autonomous, interactive and mobile properties. Due to the autonomous migration on the heterogeneous network, the mobile agent can agilely decentralize the management tasks from workstations into the network. So the network management paradigm based on mobile agent is helpful for flexible decentralization and autonomous operation of the management tasks. By integrating the benefits of both technologies, a novel distributed network management architecture based on CORBA and mobile agent is presented. The architecture becomes m
