A Distributed Network Management Model for Next Generation Internet Based on XML and Policy

As the network scale expands and the service provided by network becomes more complex, the NGI (Next Generation Internet) is coming to us. It is a difficult task to manage the NGI efficiently. XML is a new technology which can describe management information more compact and can easy the manage operations. Policy-based network management is a distributed network management model, which can make the network management more and more flexible, effective and reliable. According to the NGI's characteristics and the advantages of the XML technology and Policy-based network management model, we give a distributed network management model for NGI based on XML and policy, analyze the structure and the components of this model, and finally, a prototype that designed and implemented on above methods and technologies, named XPBNM, is introduced.
