Adaptive policy-based approach for static and dynamic policy conflict detection

Abstract

Policy-based approach has been mostly acknowledged as a methodology that separates the rules governing the behavior of a system from its functionality. It provides the ability to (re-)configure differentiated services networks so that desired Quality of Service (QoS) goals are achieved, by considering administratively specified rules. Moreover, it promises to reduce maintenance costs of information and communication systems while improving flexibility and runtime adaptability. This paper presents a brief description on the properties of the most prominent approaches, identifying their advantages and disadvantages. Some evaluation criteria have been used to determine our research direction. We strongly believe that the results presented in this paper may provide some foundations to develop our framework. Furthermore, the proposed framework depends on static and dynamic analysis to reduce potential errors and avoid potential conflicts.
