In this work, we will focus on the work undertaken in the specification of policies, the different notations developed, and how policies are deployed within a managed system. We will motivate, analyze, and classify all major existing policy notations through several criteria and try to consider the consistent merging of their strengths into a more appropriate framework. We also propose a set of enhancing features to existing policy specification notions namely domain membership rules, role compatibility rules, and light events. The work ends by an enumeration of the set of features which a policy specification language needs to model in order to facilitate the process of implementing adaptive Quality of Service management and rapid deployment of customized services.
