On the approximation of ISP and user utilities from quality of experience

While the network quality research has been oscillating between user- and technology-driven viewpoints, the evolution of a utility-centric perspective is still a good way off. Today, not only insufficient data exists on network quality market figures, but also on the user´s usage appreciation across service types and test ranges. Filling those research gaps, the present work presents a novel model, mainly constructed around existing empirical Quality of Experience (QoE) materials, which approximates both ISP and user utilities. A focus is set on the case of controlled quality and service degradations that intelligently adapt services upon resource shortages. In a case study, this model is applied to the case of Video on Demand services.
