A Network Management Architecture Using XML-Based Policy Information Base

摘要

XML is being used to describe components and applications in a vendor and language neutral. Therefore it already has a role in distributed system. XML is also being used as a data interchange format between components and applications in loosely coupled large-scale application. Until now, policy is described for specific applications and devices. Its use has been very limited. In current network management system, we can only invoke predefined operations and actions using policy-based Network Management. The main motivation for the recent interests in policy-based networks is to support dynamic adaptability of behavior by changing policy without receding or stopping system. For these reasons we present the use of the XML for describing the policy and PIB(Policy Information Base) in COPS-PR. It improves flexibility and interoperability among heterogeneous network systems. It also can add new functionality into network components. In this paper, we propose a network management Architecture using XML-based policy information base.
