Priority classes and optimum pricing for contents delivery systems

摘要

For contents delivery systems, the service is considered in which the price depends on each priority class. This paper deals with the multiple priority classes of the contents delivery system from the viewpoint of the utility and pricing. The willingness-to-pay (WTP) is introduced as a measure of utility, which is regarded as the price, and the optimum condition is analyzed to maximize the user's utility as well as the provider's revenue. For the system with multiple priority classes, the optimum condition is given in terms of the traffic load, waiting time for service and price for each priority class. The optimum number of priority classes is also discussed.
