NETQOS architecture and components TELEFÓNICA I+D © 2008 Telefónica Investigación y Desarrollo, S. A.

NETQOS Components Actor Preference Manager (APM) for actor oriented business level Qo. S policies; Policy Description and Management (POLD) allowing unified policy access / storage; Policy Repository Automated Policy Adaptor (APA) for policy provisioning and parameter change; Monitoring and Measurement (Mo. Me) for policy monitoring and event detection; Net. Agent for automated policy configuration at network entities; Trans. Agent for automated policy configuration at transport entities; Context Manager for control of interactions between different components.

User Centric Qo. S Policy Management Interfaces Scenario and ontology based management interface Interface offers specification of business level Qo. S 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 TELEFÓNICA I+D © 2008 Telefónica Investigación y Desarrollo, S.

Qo. S Policy Management User Interface User select preferences for his applications selecting Qo. S and preferred networks NETQOS tools check user requests according SLAs and produce corresponding policies based on translation of preferred Qo. S and networks to configuration policies.

Conclusion: NETQo. S Benefits User can specify / change own Qo. S 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 Qo. S mechanisms for heterogeneous environment using policies Automated policy monitoring considering SLAs Automated detection of business Qo. S policy violation using monitoring Automated adaptation of Qo. S policy parameters/mechanisms at configuration layer in order to improve the Qo. S policy provisioning at the business level SLA related Qo.

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” TELEFÓNICA I+D © 2008 Telefónica Investigación y Desarrollo, S.
