Los Angeles to Geneva Link Achieves Throughput Rate of 6.25 Gbps Using Standard TCP/IP Protocol

Cupertino, CA. and Ottawa, Canada — April 20, 2004 — Neterion Inc. (formerly S2io Inc.), Inc., an emerging leader in high-speed server and storage I/O solutions, announced that the company joined forces with Caltech, CERN, Cisco and Microsoft to send data a distance of 10,949 kilometers (6,569 miles) at a rate of 6.25 Gbps using the industry standard TCP/IP protocol. This is a new world record in the IPv4 multi-stream category. The data rate equates to 68,431,250,000,000,000 meter-bits per second. The Internet2® Land Speed Record (I2-LSR) is an open and ongoing competition for the highest-bandwidth, end-to-end networks

The network elements included Neterion's Xframe® 10 GbE server adapter, Microsoft Windows Servers 2003 for 64-Bit Itanium-based Systems and Cisco 7600 Series Routers. The labs at Caltech in Los Angeles and CERN in Geneva, Switzerland served as leads and hosts of the event. The project was co-funded by the U.S. Department of Energy, the National Science Foundation and the European Union.

The record was certified by the Internet2 - Land Speed Record Group. Internet2 is a consortium led by 206 universities that works in partnership with industry and government. One of its goals is to ensure the rapid transfer of new network services and applications to the broader Internet.

"We're pleased to have been an integral part of the team that achieved this record breaking performance," said Dave Zabrowski, President and CEO of Neterion. "This is another example of the power of 10 Gigabit Ethernet technology that is rapidly gaining acceptance in research institutions and corporate data centers."

The team utilized Abilene, the most advanced research and education network in the United States. The Internet2 backbone was just upgraded from 2.5 Gbps to 10 Gbps making it 15,000 times faster than the typical home broadband connection.

"This is an important step towards production-quality high throughput data services that can be used by a broad community of users in both the research and commercial sectors. The ability to transfer data reliably at these high speeds, on demand, will have a profound effect on next generation Grid systems," noted Dr. Harvey Newman, Professor of Physics at Caltech and Collaboration Board Chair of US CMS (*United States Compact Muon Solenoid). "In addition to meeting the leading edge needs of the major programs in high energy physics and many other fields of data intensive science, these developments can be applied to build integrated systems for the sharing of corporate data and large-scale content distribution over national and transoceanic distances."

According to Dr. Les Cottrell, Assistant Director of Computer Services at the Stanford Linear Accelerator Center, at 6.3 Gbps the entire print content of The Library of Congress (10 terabytes of data) could be transmitted in about 3 and one-half hours.

Members of the team will be recognized at the Spring 2004 Internet2 Members Meeting being held April 19 - 21 in Arlington, Virginia.
