Pricing of Differentiated Services such as DiffServ

1.在互联网上，对保证质量的服务的需求正在增加。差异化服务将被引入，以使用优先级控制提供两个或更多的类。有必要知道如何收取高质量的服务。通过主观实验和问卷调查，给出了保证最低带宽与支付意愿之间的定量关系。用户对流媒体服务质量的需求取决于内容的内在特征。对几种内容进行了主观评价实验。通过主成分分析，揭示了内容特征与内容类型之间的关系。然后，根据图像质量和声音质量，通过聚类分析将内容分成若干组。将用户行为模型应用于每月统一费率的情况下，给出了保证带宽服务中收益最大化的最优价格，仿真结果显示了用户效用或加入概率与价格之间的关系。最优定价函数用幂函数估计。在内容交付服务中，预测用户的需求并提供与之匹配的服务是很重要的。利用付费意愿模型对具有优先级控制的内容交付服务中的用户行为进行建模，实现用户利益和提供商收益的最大化。结果表明，用户的最优定价与供应商的最优定价存在差异。

1.The necessity for the service which guarantees quality is increasing in the Internet. The differentiated service is going to be introduced to offer two or more classes using priority control. It is necessary to know how to charge the high quality service. The quantitative relation between guaranteed minimum bandwidth and willingness to pay is shown by the subjective experiment and the questionnaire survey.2.User's demand fur the quality of streaming services depends on the intrinsic characteristics of the content. The subjective evaluation experiment is done for several kinds of content. The relation between content characteristic and content type is shown by using principal component analysis. Then, based on the image quality and the sound quality, the contents are divided into several groups by cluster analysis.3.The optimum prices to maximize revenue in guaranteed bandwidth services are proposed in case of flat rate price per month Disaggregate behavioural model is applied to the user's behaviour, and simulation results show the relation between user's utility or join probability and price. The optimum pricing function is estimated by power function.4.In content delivery services, it is important to predict users' needs and to provide the services matching up to them. The user's behaviour in content delivery service with priority control is modeled by using willingness to pay, and the users' benefit and the provider's revenue are maximized. As a result, it is shown that the optimal pricing for users and that for provider are different.
