Peer-To-Peer (P2P) technology has been regarded as a promising way to help Content Providers (CPs) cost-effectively distributes content. However, under the traditional Internet pricing mechanism, the fact that most P2P traffic flows among peers can dramatically decrease the profit of ISPs, who may take actions against P2P and impede the progress of P2P technology. In this paper, the authors develop a mathematical framework to analyze such economic issues. Inspired by the idea from cooperative game theory, they propose a cooperative profit-distribution model based on Nash Bargaining Solution (NBS), in which eyeball ISPs and Peer-assisted CPs (PCPs) form two coalitions respectively and then compute a fair Pareto point to determine profit distribution. Moreover, they design a fair and feasible mechanism for profit distribution within each coalition.
