The Celtic Plus Quality of Experience Estimators in Networks (QuEEN) project was conceived to create a suitable conceptual framework for Quality of Experience (QoE). This chapter presents some of the conceptual results produced so far within QuEEN (and other related activities, such as COST Action IC1003 Qualinet). It provides an overview of the QuEEN project's approach for estimating QoE for generic services, and exploiting these estimates in various ways. The chapter proposes a conceptual framework for understanding QoE, for different services and in different timescales, as well as a model to make this conceptual framework operational. The QuEEN agent provides a flexible distributed implementation of the QuEEN layered model, allowing us to estimate the quality of different services in different locations, and to feed those estimates to QoE-aware applications, such as monitoring, network management, or service level management, to name a few.
