摘　　要：部署域间多径路由是一个复杂的问题,而运营商由此产生的收益变化将直接关系到域间多径路由方案是否会被运营商接受并推广。从用户效用的角度出发,建立了运营商收益的优化模型,并对比了单一路径及多可达路径下运营商收益的变化情况以及各相关因素之间的影响关系。理论及仿真结果表明,采用多可达路径将给运营商带来更大的利润空间,并可为更多的用户和时延敏感类业务提供服务支撑。The multipath inter-domain routing is a complex topic,but profits of Internet Service Provider（ISP） are one of the most important factors for the prospect. We established an optimization model for profit of ISP based on the user＇ s utilities. Then, the ineensement of profit from single-path routing to multipath routing and the impact of relevant factors were analyzed. Through theoretical analysis and simulation experiments, we found that ISP can acquire more profit when muhipath routing was deployed. Moreover, it can offer better service for more users and delay sensitive traffics.
