摘　　要：深入分析了DiffServ网络中接纳控制方法的缺点,提出了一种新的接纳控制方法。该方法将边界和内部接纳控制分开进行。边界接纳控制时,采用边界区分服务策略,根据流对QoS不同要求,将流分为两类区别对待,不但提高了网络资源利用率,而且保证了流的服务质量;内部接纳控制时,采用了基于路径的方法,大大提高了网络接纳控制的效率。This paper analyzes the problems of current admission control schemes in DiffServ networks. A new admission control scheme is proposed. The scheme divides admission control into two phases: edge admission control and interior admission control. During the edge phase, it uses differentiated services strategy. The flow requests are classified into two classes and get differentiated services according to their QoS demands. This strategy effectively improves the utilization of network resource and guarantees the flows QoS. During the interior phase, the path-based algorithm is adopted, which greatly improves the efficiency of admission control.
