MCNC LICENSES HIGH SPEED NETWORK ANALYZER TO IOSC

 MCNC LICENSES HIGH SPEED NETWORK ANALYZER TO IOSC
 RESEARCH TRIANGLE PARK, N.C., Aug. 18 /PRNewswire/ -- Alan Blatecky,


Vice President for Communications at MCNC, announced today that the Center for Communications at MCNC has agreed to license a unique high-speed network analyzer to Input Output Systems Corporation (IOSC) of Mountain View, Calif., for commercial production. The technology transfer agreement provides that MCNC will earn royalties as IOSC sells the new product.
 The system, called HiLDA (for HIPPI Link Data Analyzer), monitors a variety of traffic statistics on networks at speeds of 800 million bits per second. These networks are commonly used in supercomputing centers to move data among the world's fastest computers. HiLDA permits operators to look at the performance of supercomputer networks and track down problems that may occur.
 "The data rates on HIPPI are so high that the trick has been to find reasonable ways to display traffic information," says Jon Whaley, the Center for Communications' software engineer. Whaley and hardware engineer Dan Winkelstein built HiLDA to solve that problem.
 Winkelstein says the system was designed, and is being used at the Center for Communications for work on a three-year project called VISTAnet that is exploring the technology needed to move vast amounts of information, including medical data and computer images, at tremendous speeds of 1 billion bits per second (a gigabit) using the High-Performance Parallel Interface (HIPPI) standard.
 Winkelstein says, "HiLDA originally began when the VISTAnet project needed a tool to measure what was happening on the HIPPI links at each end of the network. We took that idea and built a powerful system that performs network analysis."
 Winkelstein and Whaley took the idea of a network analyzer from a one paragraph concept to a full scale system in about two years and installed the original system at two corporate sites.
 "When we finally got done," Winkelstein says, "HiLDA showed promise for doing things you cannot do any other way." And that's apparently what attracted IOSC.
 IOSC President Joe Parker says, "The addition of the HiLDA system nicely complements our existing product line. We are impressed by the functionality of HiLDA and expect it will be of great benefit to our customers." IOSC's current products include a HIPPI channel tester, a HIPPI 4X crossbar switch and a HIPPI frame buffer. IOSC will market HiLDA analyzers based on the MCNC design for immediate product availability.
 "We plan to co-develop additional features for HiLDA with IOSC at a later date," says Dan Stevenson, director of communications research in MCNC's Center for Communications. BACKGROUND
 The Center for Communications is a division of MCNC in Research Triangle Park, N.C. The Center manages the CONCERT network that includes two-way, interactive audio and video links interconnecting eight universities and four medical schools and data links with ten thousand computers at businesses and universities across the state.
 The Center's Research Department is currently working on the second year of the three-year VISTAnet project. Responsibilities include communications research and overall project coordination of the project that also involves computer scientists at UNC-Chapel Hill, and communications experts at N.C. State University, GTE and BellSouth. VISTAnet is funded jointly by the National Science Foundation and the Defense Advanced Research Projects Agency. Additional funding for VISTA net is provided by BellSouth and GTE.
 The Input Output Systems Corporation in Mountain View, Calif., founded in 1988, develops, manufactures and markets products for users and vendors of high-performance computers based on the ANSI HIPPI standard.
