This paper studies the evolution of policy-based management and examines some of the proposed architectures for the management of networks and services, evaluating their advantages and disadvantages.

A comparison is made among three representative models on general architecture attributes, policy-related attributes, and general evaluation metrics for scalability, reliability and performance. This analysis leads to the observation that there are important shortcomings in all models, among them the limited scope of the policies used. This is a major issue for provision of end-to-end quality of service (QoS) in heterogeneous, multi-provider networks.

Using the information collected, and considering the necessities of modern Internet applications, a model for a policy-based management architecture is derived. It is scalable, technology independent and capable of providing end-to-end QoS.
