Internet2 Selects Glimmerglass Intelligent Optical Switches for Nationwide
Advanced Network Testbed

HAYWARD, Calif. & ANN ARBOR, Mich.-- July 20, 2005-- Glimmerglass, a pioneer
in automated fiber management and Internet2 corporate member, today
announced that Internet2, the foremost U.S. advanced networking consortium
led by the research and higher education community, has selected
Glimmerglass Intelligent Optical Switches for deployment in five national
network nodes located in Seattle, Washington D.C., New York, Chicago, and
Los Angeles.

Internet2's Hybrid Optical and Packet Infrastructure (HOPI) project is
building a national network testbed to examine the requirements and
performance of scalable next generation networks that combine the best of
packet and optical technologies. The Glimmerglass switches will be used in
this national-scale testbed to dynamically provision high-bandwidth optical
data circuits between network interfaces. The HOPI project is developing and
testing a network that will perform this process on demand as opposed to
traditional provisioning intervals that can take weeks or months.

"The Glimmerglass optical switches offer extraordinary flexibility deep
within our network infrastructure by enabling switching and set up of
circuits in virtually any node," said Rick Summerhill, Internet2's director
of network research, architecture and technologies and HOPI Design Team
co-chair. "These switches can essentially re-cable all of the physical fiber
connections between network interfaces, optical devices and equipment on the
fly, in milliseconds, remotely and at the touch of a button. Moreover, the
Glimmerglass switches are particularly appealing because they are easy to
use and simple to integrate into our network."

The HOPI nationwide testbed serves as a foundation for cutting-edge network
experimentation and a model for the next-generation of Internet2's existing
high performance packet-based Abilene network. It will utilize facilities
from the Abilene Network, the MAN LAN exchange point, the nationwide
National LambdaRail (NLR) optical infrastructure and several regional
networks.

"The future network architecture is being built right now by the Internet2
community," said Robert Lundy, Glimmerglass' chief executive officer. "We're
excited that the HOPI team selected our company and is relying on our
products to support such an important national program."
