Abstract-- Policy-based network management is a necessity
in managing large scale environments. It provides means for
separating high level system requirements from actual implemen-
tation. As the network size increases the need for automated tools
to perform management increases rapidly. Configuring routers
and network devices to achieve Quality of Service goals is a
challenging task. Using Differentiated Services to dynamically
perform this configuration involves defining policies on different
network nodes along multiple domains. Policy aggregation across
domains requires a unified policy model that can overcome the
challenge of conflict detection and resolution. In this work, we
propose a unified model to represent and encode QoS policies
that will result in efficient and flexible conflict analysis ability.
The representation utilizes a bottom-up approach, from the
base policy parameters to the aggregation of overall policy
