【摘要】 在提供区分服务的定价方法中,Marbach提出的静态定价方法假设各个优先级的价格事先确定,如果ISP诚实,在用户进入市场后I,SP无法影响用户的服务选择来增加效用。如果ISP不诚实,通过伪造用户使用网络,从而影响用户的服务选择,由此增加效用。用户意识到ISP可能伪造,会采取检查网络市场的对策来确保ISP诚实。对于伪造的经济分析以及用博弈论方法进行的分析都表明ISP有可能伪造。毫无疑问I,SP伪造改变了用户和ISP的行为与效用,具体例子也说明了伪造的影响。更多还原

【Abstract】 The influence of ISP’s forging in static pricing scheme for priority services is analyzed.If ISP is honest,having determined the price of each priority,afterusersenterthe network market,it can’taffect the market;ifit forges,itcan change its utility.In response to forging,users may adopted their traffic allocation vectors to maximize their net benefit.If users submit more traffic or in higher priority service class,ISP gains form the behavior;if users submit less traffic or even exits the market,ISP’s utility decrease.The analysis using the game theory proves that forging is possible.When ISP gains more than its loss,ISP will take the action.The market is completely different from that before,and it is changed by forging.Several examples are presented to illustrate the results.更多还原
