User-centered control of quality of service

As users of the Internet, we have come to expect to receive a large range of services for a flat rate, and to have an ever widening ``data pipe'' allowing us to transfer bigger movies faster. Whether or not such a model makes business sense or theoretical sense is not our point. Rather, we consider that there are still occasions when we will reach the limit of the capacity of the network, if not in the access, then further inside the networks. In such a case, a differentiated-services model can be useful to help more performance-critical applications, but which are the critical applications, and how can they be recognized without breaking the Internet model and giving the ISP control over our environment.In this project we pursue an investigation on the user control of service classes for end-to-end services in the Internet. We plan to demonstrate the soundness of such a model to deliver large-scale user satisfaction for generic Internet access, but also its usefulness for the operator as it offers a model for consumption-based revenues.This model is unique as it preserves the freedom of choice of the user to choose and deploy applications, while yet allowing the ISP to help the user with a service differentiation, and minimizes exchanges between the two.
