项目摘要

9.1. Performance of ATM multicast switch with separate mutes depending on unicast cell/multicast cellThis paper proposes a new architecture for the ATM multicast switch, which makes unicast cells and multicast cells inputted to the corresponding separate mutes before the point to point routing network. By reducing excess load of the copy network, this new multicast switch can make mean system time smaller than one of a model which is a serial combination of a copy network and a routing. In addition, we also show the simulation of the cell loss probability in our proposed model.92. Input and output queueing ATM switch with two speedup factorsInput and output queueing ATM switch model with two speedup factors to decrease cell loss probability is proposed. In the proposed model, large speedup factor is basically used, however, small speedup factor is adopted when in the previous time slot the output queue exceeds the threshold. We analyze the mean waiting time and the cell loss probability under uniform traffic. As a results, we show that the proposed model is useful to decrease the cell loss probability without increase the cell loss probability without increasing the mean waiting time excessively.9.3. Performance analysis of input and output queueing ATM switch under changeable hot-spot trafficSwitch performances of input and output queueing ATM switch under the changeable hot-spot traffic is analyzed. In the changeable hot-spot traffic, the number of hot-spot, its location and the deviation of traffic is changeable. This traffic is close to the realistic traffic model compared with the conventional hot-spot traffic. We analyze the cell loss probability and mean system delay for this switch and traffic models and show numerical results for the cell loss performance under various traffic conditions. And the influence of the hot-spot traffic on the cell loss performance are shown.

9.1.具有单独静音的ATM组播交换机的性能取决于单播信元/组播信元本文提出了一种新的ATM组播交换机架构，使得单播信元和组播信元在点对点路由网络之前输入到相应的单独静音。通过减少复制网络的过量负载，这种新型组播交换机可以使平均系统时间比复制网络和路由串联组合的模型更小。此外，我们还展示了我们提出的模型中细胞丢失概率的模拟。92。具有两个加速因子的输入和输出排队ATM交换机为了降低信元丢失概率，提出了具有两个加速因子的输入和输出排队ATM交换机模型。在所提出的模型中，基本上使用大的加速因子，但是当在前一个时隙中输出队列超过阈值时，则采用小的加速因子。我们分析了均匀流量下的平均等待时间和信元丢失概率。结果，我们表明所提出的模型对于降低信元丢失概率而不增加信元丢失概率而不过度增加平均等待时间是有用的。9.3。热点流量变化情况下输入输出排队ATM交换机的性能分析分析了热点流量变化情况下输入输出排队ATM交换机的性能。在多变的热点流量中，热点的数量、热点的位置以及流量的偏差都是可变的。与传统热点流量相比，该流量更接近现实流量模型。我们分析了该交换机和流量模型的信元丢失概率和平均系统延迟，并显示了各种流量条件下信元丢失性能的数值结果。并显示了热点流量对信元丢失性能的影响。
