本文描述了一种新型的IP电话端点准入控制机制：PCP-DV，它具有两个基本特征。首先，除了将不同的服务优先级应用于探测和数据分组的能力之外，它不依赖于内部网络路由器中的任何附加过程。第二，用于连接接纳决策的触发机制基于对探测流上的延迟变化统计的分析。一个IP电话业务的情况下的数值结果证明，99日延迟不大于几毫秒每路由器的保证，即使在过载条件下。
In this paper we describe a novel endpoint admission control mechanism for IP telephony:the PCP-DV which is characterized by two fundamental features. First, it does not rely on any additional procedure in internal network routers other than the capability to apply different service priority to probing and data packets. Second, the triggering mechanism for the connection admission decision is based on the analysis of the delay variation statistics over the probing flow. Numerical results for an IP telephony traffic scenario prove that 99th delay percentiles not greater than few ms per router are guaranteed even in overload conditions.
