NGN usage in Future Internet scenarios

Overlay applications are generating the most of the traffic in today's Internet. Therefore, ISPs have to consider the optimization of this traffic and its associated operational costs. This paper presents the approach of the SmoothIT project to improve the end users' QoE and to reduce the ISPs costs. This approach is based on the specification of Economic Traffic Management mechanisms that are implemented in the “SmoothIT Information Service” architecture. This architecture can take advantage of the usage of NGN transport control functionalities, providing improved QoE to the end users of the overlay applications.
