RIA: THE STUDY OF TIME-DEPENDENT BEHAVIORS OF VOICE/DATA INTEGRATED NETWORKS AND CSMA/CD NETWORKS

在多媒体环境和使用载波侦听多址协议的随机接入网络中使用的语音/数据集成复用器在现代通信中继续被广泛使用。因此，重要的是要尽可能完整地理解它们。其中最重要的问题之一就是研究它们的时间相关或暂态性能。这个项目的目标是：1)获得一个理论和计算框架来评估这些网络的随机模型的暂态行为，这些网络的参数也可能是平稳的或依赖于时间的。2)评估话音/数据综合网络和多路访问网络的暂态性能，这是稳态分析无法得到的。要分析的模型包括具有可移动边界分配的语音/数据集成交换机、具有更真实的分组长度到达过程描述的网络模型、多分组或多活动用户到达以及网络稳定性分析。3)根据语音/数据交换机的时间/依赖行为，设计了一些动态的路由和控制方案。4)推广研究更基本的排队问题的方法。

Voice/data integrated multiplexers employed in multimedia environments and random access networks using the Carrier Sensing Multiple Access protocols continue to be widely used in modern communications. Therefore, it is important that they be understood as completely as possible. One of the most important problems is to study their time dependent, or transient performance. This project's objectives are: 1) to obtain a theoretical and computational framework to evaluate the transient behavior of stochastic models for these networks, whose parameters may also be stationary or time dependent. 2) To evaluate the transient performance of voice/data integrated networks and multiaccess networks, which cannot be found using steady state analysis. Models to be analyzed are the voice/data integrated switches with movable boundary assignments, network models with more realistic descriptions of packet length arrival processes, multi-packet or multi-active-user arrivals, and the network stability analysis. 3) The design of some dynamic routing and control schemes in voice/data switches based on their time/dependent behaviors. 4) To generalize the approach to the study of more fundamental queueing problems.
