(1) Characterization of Multimedia TrafficFrom the data analysis for a sequence of frames generated by MPEG2 variable bit rate encoding of a motion picture video, we have computed the Hurst parameter values as a measure of long-range dependence in the traffic source process.(2) Performance Evaluation of the D Channel Access Control Scheme in ISDNBy the analysis of stochastic process and simulation for a model of the D channel access control scheme in the ISDN basic user/network interface, we have evaluated the throughput and mean waiting time for both signal and packet transmission from the terminals to the network.(3) Analysis of Queueing SystemsWe have studied a number of queueing systems with priority-based service scheduling including cyclic priority (polling models) and preemptive loss priority discipline. We have also developed several procedures for calculating the higher-order moments of the waiting time using Mathematica software.

(1)多媒体流量的表征通过对一个运动视频的MPEG2可变比特率编码产生的帧序列的数据分析，我们计算了Hurst参数值作为流量源过程中远程依赖性的度量。(2) ISDN中D通道接入控制方案的性能评估通过对ISDN基本用户/网络接口中D通道接入控制方案模型的随机过程分析和仿真，评估了终端向网络传输信号和分组的吞吐量和平均等待时间。(3)排队系统的分析我们研究了一些基于优先级的服务调度的排队系统，包括循环优先级（轮询模型）和抢占损失优先级原则。我们还开发了几个程序，用于使用Mathematica软件计算等待时间的高阶矩。
