摘　　要：Internet Qos(服务质量)评估是多学科领域的研究问题,本文从博弈理论的视角,基于多项罗吉特(MNL) 模型提出了综合考虑服务质量指标和价格因素的Internet QoS评估机制。采用MNL建模用户的选择行为,同时将各个业务类表示为相对独立的竞争实体,每个业务类最大化自己的效用。通过基于非协作博弈理论的分析,论证了各个业务类的QoS指标和价格之间存在均衡,并通过数值分析进行了验证。The evaluation of Internet QoS （Quality of Service） is naturally multi-discipline. This paper examines the Internet QoS evaluation by integrating QoS index with price factor. The multinomial Iogit model is adopted in this paper, which is used to model the choice behaviour of users. Each service class is modelled as independently competitive entity. The goal of each service class is to maximize its own utility. Through the analysis based on noncooperative game, the conclusion is drawn that the equilibria exist between QoS index and price of each service class, and the numerical results is provided to verify the conclusion.
