项目摘要

The asynchronous transfer mode (ATM) switches to support Broadband ISDN have been widely studied in recent years. In order to transmit multimedia traffic efficiently, it is significant to reduce waiting time and cell loss probability in the ATM switch. Especially, the media such as voice, data and image has different request for quality of service (QoS) for waiting delay, so we need the ATM switch which can support the traffic with multiple priority classes. Also, the ATM switch is required to support a multicast traffic, which can provide teleconferencing and video on demand. Therefore, network structure and network control policy, which can treat multimedia traffic and satisfy QoS of each media, have a great effect for the performance of ATM switches. In the conventional research, performance of a switch which can support the media with multiple priorities has not been analyzed. In this research, we propose the knockout packet switch with Bacher network for multiple classes, and propose the crossbar ATM switch and the multistage ATM switch with partially buffers for multicast traffic. By performance analysis and computer simulations, we investigate basic performance measure such as cell loss probability and waiting delay in detail. As a result, we show network structure and network control policy, which can treat multimedia traffic efficiently and satisfy QoS of the media. It is expected that our proposed switches can make multimedia communication networks more efficient.

支持宽带ISDN的异步传输模式（ATM）交换机近年来得到了广泛的研究。为了有效地传输多媒体业务，减少ATM交换机的等待时间和信元丢失率具有重要意义。特别是语音、数据和图像等媒体对等待时延的服务质量（QoS）有不同的要求，这就要求ATM交换机能够支持多优先级业务。此外，ATM交换机需要支持多播业务，这可以提供电话会议和视频点播。因此，能够处理多媒体业务并满足各媒体QoS的网络结构和网络控制策略对ATM交换机的性能有很大的影响。在传统的研究中，交换机的性能，可以支持多个优先级的媒体还没有被分析。在本研究中，我们提出了多类别的淘汰分组交换与巴赫尔网络，并提出了交叉式ATM交换和多级ATM交换与部分缓冲区的组播流量。通过性能分析和计算机模拟，我们详细研究了基本的性能指标，如信元丢失率和等待延迟。在此基础上，提出了一种能有效处理多媒体业务并满足媒体QoS要求的网络结构和网络控制策略。预期我们所提出的交换机可以使多媒体通信网络更有效率。
