This paper proposes a PBNM (Policy Based Network Management) framework for automating the process of generating and distributing DiffServ configuration to network devices. The framework is based on IETF standards, and proposes a new business level policy model for simplifying the process of defining QoS policies. The framework is defined in three layers: a business level policy model (based on a IETF PCIM extension), a device independent policy model (based on a IETF QPIM extension) and a device dependent policy model (based on the IETF diffserv PIB definition). The paper illustrates the use of the framework by mapping the information models to XML documents. The XML mapped information model supports the reuse of rules, conditions and network information by using XPointer references.
