First Wire-rate OC-192c Deployment in Asia

National Center for Science Information Systems Selects Juniper Networks Breakthrough M160 Routers for Big-bang Theory Research

Mountain View, CA - March, 28, 2000 - Juniper Networks, Inc. (Nasdaq:JNPR), a leading provider of next-generation IP infrastructure systems, today announced that the National Center for Science Information Systems (NACSIS), a core research institute for inter-university information exchange in Japan, has chosen Juniper Networks new M160 Internet backbone routers for its scientific research network. One of the premier NACSIS research projects is Radio Astronomical Observation (RAO) that uses real-time Very Long Baseline Interferometers (VLBI) to measure the expansion of the universe by pulling vast amounts of data from radio telescopes and sending it to data processing equipment for sophisticated analysis. Juniper Networks high-end M160 routers will be used to move the observation data over an OC-192c fiber optic link, the first at that speed in Asia, from the radio telescopes in Nobeyama to the servers in Tokyo.

"We were looking for a routing system that could move huge quantities of data at OC-192c wire-speed, reliably, for this summer," said Dr. Shoichiro Asano, professor at NACSIS. "By knowing we can get reliable 10 Gbps transmission speeds we greatly improve the sensitivity and resolution of optical imaging that we need for large-scale surveys of astronomical bodies. Juniper Networks new M160 router was the only product available today that could do this."

Applications like RAO research that require routing of extremely large amounts of data are driving the need for more and more optical bandwidth. "Juniper Networks enables our customers to capitalize on the ever-increasing optical bandwidth with a powerful combination: the first wire-rate OC-192c interface and reliable processing performance for any packet size under any networking condition," explained Scott Kriens, chief executive officer and president of Juniper Networks.

NACSIS is the first IP infrastructure in Asia to deploy OC-192c fiber optic links in a live network. NACSIS has already deployed M20 Internet backbone routers across their next generation network, testing enhancements to the Science Information Networks (SINET) backbone network for their universities and research institute. SINET is the largest research network in Japan. The network is scheduled to be operational in July 2000. Only the Juniper Networks breakthrough M160 router demonstrated the required performance, reliability, and redundancy in a shipping product to move the massive quantities of data necessary for big-bang theory research.
