摘　　要：本文研究时延QoS(Quality of Service)约束下,通信网络中混合业务的带宽估计问题。系统模型中,采用多流输入的排队系统去抽象混合业务到达的网络,用中断泊松过程(Interrupted Poisson Process,IPP)描述标签流,用泊松(Poisson)过程描述背景流。利用排队论及有效带宽理论,估计了IPP+Poisson混合业务的带宽需求。仿真验证了带宽估计结果可以满足时延QoS要求。This paper investigates the bandwidth estimation for mixed traffic in the communication networks under delay QoS(Quality of Service)constraints. In the system model, the queuing system with multiple stream input is used to abstract the networks with mixed traffic. The interrupt Poisson process(IPP) is used to describe the tagged traffic, and the Poisson process is used to describe the background traffic. Based on the queuing theory and effective bandwidth theory, the bandwidth requirements for IPP+Poisson services is estimated. Simulation results show that the bandwidth estimation results could meet the delay QoS requirements.
