Pricing of Differentiated Services such as DiffServ

1.互联网对保证质量的服务的必要性越来越大。将引入区分服务，以使用优先级控制来提供两个或更多类。有必要知道如何对高质量的服务收费。通过主观实验和问卷调查，给出了保证最小带宽与付费意愿之间的定量关系。2.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，基于图像质量和声音质量，通过聚类分析将内容划分为若干组。3.给出了固定费率下保证带宽业务收益最大化的最优价格，并将非聚合行为模型应用于用户行为，仿真结果显示了用户效用或加入概率与价格的关系。在内容分发服务中，预测用户需求并提供与用户需求相匹配的服务是非常重要的。在优先控制的内容分发服务中，用付费意愿来模拟用户的行为，最大化用户的利益和提供商的收益。结果表明，用户和供应商的最优定价是不同的。

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.
