HIGH PERFORMANCE NETWORKING ENABLES INSTRUCTION ACROSS THE PACIFIC OCEAN

December 30, 1999--Madison, Wisconsin--Even though they were separated by
over 6,000 miles, Larry Landweber and Jun Murai are teaching courses
together this semester. Landweber, a computer science professor at the
University of Wisconsin, Madison in the United States and Murai, a professor
at Keio University just outside Tokyo, Japan, have used high performance
networking to link their classrooms for the past three months.  The two
professors served as guest lecturers for each other's classes as nearly 60
graduate computer science students learned about the networking technology
being used to bring their classes together.

The advanced networking link enabled much higher quality video and audio
than is typically possible on the World Wide Web today.  Full-screen,
TV-quality pictures and high-fidelity audio allowed a professor lecturing at
one site to call on, and answer questions from, students in the classroom at
the other end. The project also allowed students to review lectures
throughout the semester, as video recorded during lectures was stored
digitally and available for students to review online. The network link
between the two classrooms used the next generation of Internet Protocol, or
IPv6 rather than IPv4, which is the protocol used in most of today's
commercial Internet. Students from Keio University, Nara Institute of
Technology and University of Wisconsin, Madison participated.

However, not all of the challenges the project faced were technical. As
Professor Landweber noted, the classroom cultures in Japan and the United
States are very different, and adapting teaching styles to these differences
presented as great of a challenge as getting the technology to work.

Southwest PA Connects to Advanced Internet2 Network


Pittsburgh -- Universities and research centers in the Southwest 
Pennsylvania region can now connect to one of the most advanced 
research networks in the U.S. Through a fiber connection implemented 
in December, the high-performance network hub at the Pittsburgh 
Supercomputing Center, called a gigaPoP, is now linked to Abilene, an 
advanced research network that currently links over 90 U.S. 
universities and research organizations.

"We're proud to bring the advanced capabilities of Abilene to this 
region and to support these universities in their efforts to develop 
innovative network technologies," said Gwendolyn Huntoon, director of 
the National Center for Network Engineering, a PSC resource group.

Abilene is a backbone network of the Internet2(tm) project, a 
consortium of universities and corporations working to accelerate the 
next stage of Internet capabilities and applications. Abilene 
transmits data at 2.4 billion bits per second, 40,000 times faster 
than a typical modem.

The Pittsburgh gigaPoP, operated by NCNE, acts as a hub providing 
connectivity for Carnegie Mellon University, the University of 
Pittsburgh, Pennsylvania State University and PSC to advanced 
research networks, such as Abilene, and the Internet. The gigaPoP 
directs traffic onto Abilene at speeds up to 155 million bits per 
second.

Pennsylvania universities will use the Abilene network for developing 
new applications in research and education. "The Abilene network 
provides our faculty and students with a powerful new tool with which 
to develop innovative applications to enhance instruction and 
research," said James V. Maher, provost and senior vice chancellor of 
the University of Pittsburgh.

Penn State, one of the charter members of Internet2, has been 
expanding its use of Internet2 backbone networks for the past several 
years. "We expect that our Internet2 backbone usage will continue to 
grow at a dramatic rate (more than doubling in less than six months) 
as new applications move from test environments into production," 
noted J. Gary Augustson, vice provost for information technology at 
Penn State. "Abilene is essential to this progress."

The Pittsburgh Supercomputing Center is operated by Carnegie Mellon
University in consultation with the University of Pittsburgh and with the
assistance of Westinghouse Electric Company. It was established in 1986 and
is supported by several federal agencies, the Commonwealth of Pennsylvania
and private industry.

The North Carolina Research and Education Network and Litton Network
Access Systems Partner to Deliver Video over IP to the North Carolina
Community


January 10, 2000- Research Triangle Park, North Carolina- The North
Carolina Research and Education Network (NCREN), a high performance
video and Internet network operated by MCNC, has partnered with Litton
Network Access Systems (LNAS) to deliver high quality, cost effective
distance education and videoconferencing solutions to the higher
education community and medical schools of North Carolina.

"We are proud to partner with Litton and be among the first to use
Internet Protocol (IP) to distribute courseware. This partnership has
proved instrumental in meeting our challenge to deliver high quality
videoconferencing solutions to our clients over the Internet and at a
reasonable cost. Our deployment of Litton's MPEG-2 encoder-decoders
(codecs) makes this the largest implementation of MPEG-2 technology over
IP in a production-service environment," stated Alan Blatecky, Executive
Director of NCNI and Vice President of Information Technology at MCNC.

Louis J. Tabor, President of LNAS, stated that, "MCNC recognized early
on
that MPEG-2 video over IP would position North Carolina as a technology
leader in advanced research and distance learning.  The Internet2(tm)
organization and many of its university members have also arrived at
similar conclusions.  Litton Network Access Systems is pleased to
partner with MCNC to provide broadcast-quality video to the classrooms,
research labs, and medical facilities of North Carolina."

    - more -


NCREN installed 35 Litton codecs at various sites across the state of
North Carolina, from Elizabeth City State University in the east to and
Western Carolina University in the west. The Litton codecs replaced DV45
digital video codecs, which required separate ATM circuits; the NCREN
implementation converges Internet traffic and video into a common IP
circuit.


About NCREN

The North Carolina Research and Education Network, located in Research
Triangle Park, is a high performance video and Internet network operated
by MCNC to provide support and services to the higher education
community and medical schools in North Carolina. The network operates
multiple channels of broadcast quality interactive video and audio used
to support face-to-face instructional, research, and collaborative
initiatives of the North Carolina university system. More than 50
interactive video facilities across the state can connect to NCREN. For
more information about NCREN, please see:  http://www.ncren.net/.


About Litton Network Access Systems

Litton Network Access Systems, a Virginia-based division of Litton,
provides MPEG-2 videoconferencing  products to users of advanced
