Laboratory Testbed for Technology Demonstration
With partial sponsorship from the NSF/CISE Instrumentation Grant for Research Program, we have built at the Ohio State University a laboratory testbed which consists of a Myrinet LAN of seven SUN workstations and two Pentium PCs interconnected by 4-port and 8-port Myrinet switches and Myrinet host interfaces. This laboratory testbed will be used for development of communication software and for technology demonstration on a representative embedded real-time or multimedia application.
We will also port, by inserting a thin layer called IP/ARP over ATM, the software to an ATM testbed, called the Ohio Communications and Computing ATM Research Network (OCARNet), to its support isochronous services for time-critical applications. OCARNet is funded by the Ohio Board of Regents Investment Fund, under the leadership of Dr. Raj Jain, for the purpose of conducting state-of-the-art research in network management, parallel and distributed computing, and multimedia applications. It connects OSU (Ohio State University), OSC (Ohio Supercomputing Center), OARNet (Ohio Academic Research Network), KSU (Kent State University), CSU (Cleveland State University), UD (university of Dayton), Wright State University, University of Cincinnati, and University of Toledo. OARnet will act as the central hub for the network. It will also provide points of presence (POPs) at various cities for connection to different universities. Such a network, unlike a production network, provides flexibility to experiment and validate our proposed research and demonstrate the significance of our solutions.
With the help from our industry partners, we will define and develop a representative real-time multimedia application. This application will be demonstrated on the Myrinet laboratory testbed and the OCATNet, illustrating the key functional, highly predictable, timely, and dependable characteristics of the communication software implemented.
