Mechanisms for cost-effective P2P traffic management

Overlay applications are generating most of the traffic in today's Internet. Therefore, the impact of the increasing P2P traffic on ISP's Capital and Operational Expenditures (CAPEX/OPEX) is one of its major concerns. In this paper, an overview of ISP methods for P2P traffic management is provided. The ISP has to consider the optimization of this traffic and its associated operational costs. Therefore, the SmoothIT project approach to improve the end users' QoE and to reduce the ISP's costs is outlined.
