Relation between willingness to pay and guaranteed minimum bandwidth in multiple-priority service

In recent years, the necessity of quality guaranteed services is increasing in the Internet. The differentiated services, which have multiple classes using priority control, are being introduced. Various issues need to be addressed when providing differentiated services, such as what sort of quality should be guaranteed, and what kind of pricing should be made for the service. We address this problem by making it easier for test subjects to visualize the quality of service available with a minimum guaranteed bandwidth when evaluating the willingness to pay. In this paper, the quantitative relation between the guaranteed minimum bandwidth and the willingness to pay is shown by the subjective experiment of streaming contents and by the questionnaire survey of the waiting time for download.
