| 摘 要： | 在提供区分服务的定价方法中,Peter Marbach的静态定价方法在用户进入市场后,ISP无法影响用户的服务选择来增加自己的效用。如果ISP采取伪造用户的方法,来影响用户的服务选择:传输数据的大小和所使用的优先级组合,从而增加自己的效用。利用模拟方法对这种影响进行了分析,同时,ISP的伪造行为受用户的愿付成本、在用户使用更高的优先级传输数据时是否跟进伪造、不同优先级之间的价格比等因素的影响。

| Abstract: | The influence of ISP's forging in static pricing scheme for priority services is analyzed. If ISP is honest, be- sides the price, after users enter the network market, it can't affect the market; if it forges, it can change its utility. The analysis using the game theory proves that forging is possible, when ISP gains more than its loss, ISP will take the action. In response to forging, users may adapt their traffic allocation vectors to maximize their net benefit. If users will submit more traffic of in higher priority service class, ISP gains form the behavior, if users will submit less traffic or even exits the market, ISP's utlity decrease. The market is completely different from before, forging changes the market. Several examples are presented to illustrate the results. At the same time, how the utility function and the price affect forging is discussed. |
