Acquisition of Equipment for High-Speed Networking (ATM) Research

9413803 Chao该研究基础设施奖支持三个研究项目：(1)《组播输出缓冲ATM交换机》，(2)《ATM交换机的优先级队列管理》，(3)《ATM局域网试验床》。这些项目包括VLSI芯片设计、交换结构和拥塞控制设备原型、理论分析、计算机模拟和在高速ATM(异步传输模式)网络试验台上的实验。在第一个项目中，我们计划基于我们提出的MOBAS(多播输出缓冲ATM交换机)体系结构来制作一个32x32 ATM交换结构的原型，以演示将原型交换机扩展到大型交换机(例如，具有数百个输入和输出端口)的能力。我们将使用先进的CMOS0.8微米技术(可从NSF资助的MOSIS获得)设计和制造两个专用集成电路(ASIC)芯片。在第二个项目中，我们将首先研究几种不同的队列管理控制方案的性能和实现复杂性，这些方案结合了优先级信元丢弃和优先级信元离开方案。然后，我们将实施其中一个队列管理方案，并与ATM交换机集成。在第三个项目中，我们计划在理工大学部署一个实验性的ATM局域网。ATM局域网将通过SONET OC-3光链路(155.52 Mbit/S)连接到一个名为NYNET的广域网上，用于进行B-ISDN业务应用、分布式处理、系统性能测量、拥塞/流量控制和网络管理等各种实验。***

9413803 Chao Three research projects are supported by this research infrastructure award: (1) ``A Multicast Output Buffered ATM Switch'', (2) ``Priority Queue Management for ATM Switches'', and (3) ``An Experimental ATM LAN Testbed''. These projects involve VLSI chip design, switch fabric and congestion control device prototyping, theoretical analysis, computer simulations, and experiments on a high-speed ATM (Asynchronous Transfer Mode) network testbed. In the first project, we plan to prototype a 32x32 ATM switch fabric based on our proposed MOBAS (Multicast Output Buffered ATM Switch) architecture in order to demonstrate the capability of growing the prototyped switch to a large switch (e.g., with several hundred input and output ports). We will design and fabricate two application specific integrated circuit (ASIC) chips using the advanced CMOS 0.8-micron technology (available from the NSF funded MOSIS). In the second project, we will first investigate the performance and implementation complexity of several different queue management control schemes that combine the priority cell discarding and the priority cell departing schemes. We will then implement one of the queue management schemes and integrate with the ATM switch. In the third project, we plan to deploy an experimental ATM local area network (LAN) in Polytechnic University. The ATM LAN will be connected to a wide-area network, called NYNET, through a SONET OC-3 optical link (155.52 Mbit/s), for conducting various experiments such as B-ISDN service applications, distributed processing, system performance measurement, congestion/flow control, and network management. ***
