Recently, a large amount of content is delivered to users by content delivery services through broad-band networks. The necessity for the service which guarantees quality is increasing in the Internet, because users' requirements are diversified. Differentiated services, which have multiple classes using priority control, are being introduced. The limited network resources can be used effectively by applying priority control in content delivery services. In such services, it is important to predict users' requirements and to provide the services that suit users. In this paper, the user's behaviour in content delivery services with priority control was modeled by using willingness to pay, while the total users' benefit and the provider's revenue in two different content delivery models are maximized. One model is the content delivery service using only streaming, and the other model offers streaming and download services. In this paper, it is proved that optimal pricing for users and that for providers are different.
