Architecture for dynamic management of QoS policies for heterogeneous Internet environments

In heterogeneous Internet access network environments (UMTS, WLAN, WIMAX, WLAN DVB-T, DVB-H) there is a challenge for automated configuration and adaptation of policies aimed at management of quality of service (QoS) guarantees and resource usage. The paper is focussed on a QoS policy management architecture, which allows interaction and adaptation of QoS policies of different actors (network operator, service provider and user) using a scalable policy repository. Design issues of such an architecture are discussed, emphasising on policy information models for dynamic resource, transport and measurement adaptation in heterogeneous network environments, modular and extendable ontology driven policy repository design, as well as flexible management interfaces for policy specification.
