Abstract

This paper presents a framework for specifying policies for the management of Differentiated Services (DiffServ) networks.Although policy-based management has been the subject of intensifying research efforts, proposed solutions are oftenrestricted to condition-action rules where conditions are matched against incoming traffic flows. This results in static policyconfigurations where manual intervention is required to cater for configuration changes and to enable policy deployment. Theframework presented in this paper supports automated policy deployment and flexible event triggers to permit dynamic policyconfiguration. Whilst current research focuses mostly on rules for low-level device configuration, significant challengesremain to be addressed in order to: a) provide policy specification and adaptation across different abstraction layers and b)provide tools and services for the engineering of policy-driven systems. In particular, this paper focuses on solutions fordynamic adaptation of policy in DiffServ networks according to changes in requirements. Policy adaptation includes bothdynamically changing policy parameters and reconfiguring the policy objects.
