19. TELEFÓNICA I+D © 2008 Telefónica Investigación y Desarrollo, S.A. Unipersonal User Centric QoS Policy Management Interfaces Scenario and ontology based management interface Interface offers specification of business level QoS policy requirements of the user, which are automatically translated into intermediate and configuration policies (provisioning policies) and stored into repository Intermediate and configuration policies can be automatically adapted by the system for enhanced provisioning of user business policies User business policies automatically checked towards SLAs Dynamical change of business policies by the user possible User is enabled to analyse policy monitoring results and change appropriately his policies

20. TELEFÓNICA I+D © 2008 Telefónica Investigación y Desarrollo, S.A. Unipersonal QoS Policy Management User Interface User select preferences for his applications selecting QoS and preferred networks NETQOS tools check user requests according SLAs and produce corresponding policies based on translation of preferred QoS and networks to configuration policies.

21. TELEFÓNICA I+D © 2008 Telefónica Investigación y Desarrollo, S.A. Unipersonal Conclusion: NETQoS Benefits User can specify / change own QoS policies dynamically Policies of different actors can be analyzed using common repository Interoparability and formal specification based on ontology Mapping of business to intermediate and configuration policies Flexible selection of QoS mechanisms for heterogeneous environment using policies Automated policy monitoring considering SLAs Automated detection of business QoS policy violation using monitoring Automated adaptation of QoS policy parameters/mechanisms at configuration layer in order to improve the QoS policy provisioning at the business level SLA related QoS policy description Interaction with identity management systems for SLA and context based policy management

Unipersonal Final thoughts Christian Wolff : Ontology is the “science which studies entities in general, regarding their being an entity” Leibniz(Introductio ad Encyclopaediam arcanam): ”science of what is and what is not, of the entity and the non-entity, of things and their modes, of substance and accident”
