Study And Implementation Of WEB/CORBA-Based Network Management

The increasing scale complexity and function of the network are making network management more and more important To meet the increasing demands on network management system,the traditional system based on Manager/Agent model adopting a centralizing model has been faced with a series of hard problems:lacking integration ability;lacking expansibility;the difficulty on complex network management programming;the limited retractility caused by the high centralization of network management application. In order to solve these problems,the new model of network management system should be transplantab inter-operating -. retractable and available.Since the current key technology-CORBA in distributed object technology isintroduced to the field of network management,it has become the core technology driving the development of network management It has the unparalleled superiority:easily creating the expansible network management model;adapting to the retractility of network management system;offering open and standard interface;separating the users' interfaces from manager's code;integrating with the programming language's advantage;offering high compatibility and availability. Integrating with WEB and Java makes the network management based CORBA more stranger. In this thesis,the author made a description about her study in the field of the open computer network system combined with new network technology.First,this thesis discusses the current computer network management framework,summarizes the 'network management model,analyses the typical network management framework,and educes the developing trend of network management framework.Theii we analyse network management protocols and compare CMIP with SNMP,and discuss the problems in OSI network management and in Internet network management respectively.Computer network management technology ,the relationship between WEB,CORBA,XML and network management are also discussed in this paper. By integrating the benefits of these technologies,we bring forward the network management framework based on WEB/CORBA/Java. This architecture is of excellent characters,such as high expansibility,high retractility,standard interface,multi-planform sustainability. Based on these research,the implementation ,using a WEB/CORBA network management as a model and including Proxy Manager MIB Browser,Performance Management,is presented.Finally we summarise the deficiency of our work,and point out the R&D and perspective of network management...
