CISE Research Instrumentation: VIADUCT: A Testbed to Study Video, Image, Audio and Data Traffic on a High-Speed Network

该合同旨在建立一个测试平台，用于高速、异构、局域网络的流量实验、建模和分析。为试验台购买的设备包括三个ATM交换机，其中一个提供对其他类型网络的访问，以及一个具有广泛视频功能的高性能工作站。以下设备将连接到测试平台：位于各个实验室和研究小组的17个高性能工作站；2台服务器和工程计算机网络（ECN）的以太网骨干网，支持超过12,000个用户；以及GTE提供的至少两条T1线路，用于连接当地医院和高中。试验台将通过ECN接入互联网。这些连接将允许来自许多不同应用程序的网络流量被带入测试平台进行研究。该试验台将支持的研究包括：网络流量统计和网络控制算法的建模与分析；通信网络设计与分析；经验数据驱动的离散事件系统模拟；ATM网络中的视频和图像压缩算法面向制造和机器人遥操作的分布式仿真与可视化。＊＊＊

9422250 Coyle This award is to establish a testbed for `oth experimentation with and modeling and analysis of traffic on high-speed, heterogeneous, local area networks. The equipment purchased for the testbed includes three ATM switches, one of which provides access to other types of networks, and a high-performance workstation with extensive video capability. The following equipment will be connected to the testbed: 17 high-performance workstations located in various laboratories and research groups; two servers of, and the Ethernet backbone for the Engineering Computer Network (ECN), which supports over 12,000 users; and, at least two T1 lines provided by GTE for access to local hospitals and high schools. The testbed will have access to the Internet through the ECN. These connections will allow network traffic from many different applications to be brought into the testbed for study. The research this testbed will support includes: Modeling and analysis of network traffic statistics and network control algorithms; Communication network design and analysis; Discrete event system simulations driven by empirical data; Video and image compression algorithms for ATM networks; Distributed simulation and visualization for manufacturing and the teleoperation of robots. ***
