Foundry's BigIron 15000 Layer 3 Switches Power Japan's Largest

Internet Exchange To Provide Wire-Speed, Non-Blocking Performance

In The Most Demanding Environments

Foundry Networks(R), Inc. (Nasdaq:FDRY), a performance and total solutions leader for end-to-end switching and routing today announced that Foundry teamed with Adam Net, Ltd., a leading network solution provider in Japan to power the largest Internet Exchange in Japan. Foundry and Adam Net announced that the Widely Integrated Distributed Environments (WIDE) Project, a non-profit organization operating all the major Internet Exchanges in Japan, deployed Foundry's BigIron(R) 15000 Layer 3 switches to provide wire-speed performance, superior high availability and scalability at the heart of network where different carriers connect to each other.

The WIDE project operates several major Internet Exchanges in Japan, including NSPIXP-2, which handles more than 50 ISPs peering and 4-Gbps average Internet traffic. WIDE announced this week its plans to build a new Internet Exchange with a distributed architecture located at multiple remote sites based on Foundry's BigIron 15000 Layer 3 switches. The BigIron 15000 is a 15-slot Layer 3 switch that provides massively scalable routing performance of up to 178 Million packets per second (Mpps) in a single chassis. Foundry's BigIron products, the industry's leading 10 Gigabit ready platform, provide up to 120 Gigabit Ethernet ports in a compact form factor to deliver an immense 480 Gbps total switching capacity.

In addition, Foundry's unique operating system software, IronWare(TM), enables the Internet Exchange's future expansion with robust, scalable OSPF and BGP4 routing implementations with the capacity to support up to 200 peers and 2 million routes. Link aggregation, based on the IEEE 802.3ad standard, provides highly scalable bandwidth by aggregating up to eight individual Gigabit links into one logical link.

Adam Net, a leading network solutions provider in Japan, partnered with Foundry to provide superior network integration and customer support to provide smooth installation and deployment of the BigIron 15000 Layer 3 switches in the WIDE Project. "After extensive evaluation of various products, we selected Foundry's BigIron 15000 because of its high Gigabit port density and several standard-based solutions such as 802.1w rapid spanning tree and 802.1ad link aggregation support," said Osamu Nakamura, Ph.D., Associate Professor of Keio University and a board member of the WIDE project. Shigeki Tsukue, President of Adam Net said, "Broadband Internet Exchanges have the most demanding network environments as they handle the massive amounts of nationwide Internet traffic flows growing at a rapid pace. WIDE's deployment of the BigIron 15000 Layer 3 switches at the core of the NSPIXP2 Internet Exchange is a testimony to the superior scalability, availability and performance leadership of Foundry's products and solutions."

"Internet Exchanges are a foundation for scalable broadband national Internet infrastructures," said Bobby Johnson, president and CEO of Foundry Networks. "We are pleased that WIDE project has chosen our purpose-built Layer 3 switches to power the largest Internet Exchange to connect Japan's carriers with each other in a highly scalable environment."
