University of Tokyo sets new Internet2 land speed record using switching and optical technology from Foundry Networks

Test Network Using Foundry's Wire-Speed, 10-Gigabit Ethernet Switching and Routing Platform and the Industry's First Modular WAN PHY Transceiver Sets New Record for Single Stream IPv4 Transmission

SAN JOSE, Calif., Jan. 11, 2005 -- Foundry Networks(R), Inc. (Nasdaq: FDRY) a performance and total solutions leader for end-to-end switching and routing and Internet2(R) corporate sponsor, today announced that it provided key switching, routing and optical components for the University of Tokyo's achievement of a new Internet2 Land Speed Record (I2-LSR), as announced today by the Internet2 organization. The Internet2 LSR marks the rate at which data is transferred, multiplied by the distance traveled. The University of Tokyo team was awarded an Internet2 LSR today for single-stream IPv4 transmission for their November 2004 test that successfully transferred data at 7.21 Gigabits per second over a distance of 20,645 kilometers, surpassing the existing record by more than 20 percent.

The University of Tokyo team utilized a number of innovative technologies to stage this record-breaking test including Foundry Networks' high- performance, wire-speed, 10-Gigabit Ethernet Terathon(R) switching and routing systems, as well as its Wide Area Network Physical Layer (WAN PHY) optical transceivers, which provided end-point connections in Tokyo and at the CERN research center in Geneva, Switzerland.

"The BigIron MG8 switch, the NetIron 40G routers, and the WAN PHY provided by Foundry were key components in our achievement of this goal," said Dr. Kei Hiraki, professor at the University of Tokyo. "The record demonstrates that the data transfer bottleneck is no longer at the network layer. As I/O technology evolves, the data transfer possibilities may be endless. We plan to once again use the Foundry technology in 2005 to achieve even faster high- bandwidth, transcontinental network connections."

Foundry's BigIron(R) MG8 and NetIron(R) 40G systems offer non-blocking performance, wire-speed traffic monitoring, IronWare(TM) switching and routing intelligence, wire-speed IronShield(TM) security, jumbo frame support and as little as seven microsecond port-to-port latency. They deliver the features and performance required by the most demanding service provider and enterprise environments, such as metro Ethernet networks, enterprise backbones, high- performance and cluster computing interconnects.

Foundry's WAN PHY is the industry's first modular 10-Gigabit Ethernet Wide Area Network Physical Layer optical transceiver. It is expected to help accelerate deployments of 10-Gigabit Ethernet by enabling high-performance links between Local, Metro and Wide Area Networks (LAN, MAN and WAN) for bandwidth-intensive applications on existing SONET infrastructure. The new WAN PHY offers an attractive alternative to SONET / OC-192 infrastructure because it delivers 10-GbE bandwidth at a fraction of the cost with higher performance, and with Ethernet's improved operational simplicity. With the WAN PHY optic, Ethernet frames are encapsulated in SONET frames at OC-192 rate (1310nm SMF for 10 km distances) making it an excellent solution for connecting to DWDM devices and for carrying native 10-Gigabit Ethernet over existing OC-192c networks.

"We are delighted that our switching, routing and optical technology could assist in achieving this goal, and demonstrate the power and simplicity of end-to-end Ethernet networks for high-speed data transfer," said Ken Cheng, vice president and general manager of Layer 2/3 Switching and Routing Solutions for Foundry. "Enterprises and service providers are looking to develop more economical and efficient high-speed networks to carry voice, video, data and other business-critical application traffic. High- performance, wire-speed switching platforms such as Terathon and the 10-GbE WAN PHY are critical components that will help our customers build their next- generation networks."
