Background and architectural considerations for identity enabled user-centric QoS policy management are discussed. Different strategies for usage of identity information for enhanced QoS guarantees of users in Next Generation Internet are described. The specific focus is the user-centric identity driven QoS policy management based on the enhancement of the NETQOS policy management system developed in the EU IST project. The NETQOS architecture supports the dynamic business level QoS policy specification by different actors (users, service providers and network operators) using ontology interfaces and unified QoS policy repository, as well as automated QoS provisioning including functions for policy configuration, hierarchical policy translation, mapping and adaptation of operational policies, policy monitoring and violation detection. User-centric identity enabled NETQOS policy management supports enhanced business models aimed at dynamic and flexible specification of QoS guarantees by users for their applications considering user profiles, Service Level Agreements (SLAs) and context-aware policy provisioning.
