A SOA-based framework for cross-layer QoS adaptation in next generation networks

The paper proposes the framework for cross-layer Quality of Service (QoS) adaptation in Next Generation Networks (NGN) based on Service-Oriented Architecture (SOA) principles of system design. The aim of this framework is to establish efficient communication mechanisms among the layers that will be able to adapt dynamically to the diversity of user/application requirements, networking technologies, and provider capabilities. Moreover, the unified information structure contained in Web Ontology Language (OWL) ontologies and Semantic Web Rule Language (SWRL) rules provides the common understanding of concepts and relationships maintained and shared by the service providers and users in heterogeneous environment.
