Largest Internet Exchange in Central and Eastern Europe Delivers Reliable 10 Gigabit Ethernet Services with Force10 Networks

Force10 Networks(R), the pioneer in building and securing high
performance networks, today announced that DE-CIX, the largest
Internet exchange in Central and Eastern Europe, is deploying the
TeraScale E-Series(R) family of switch/routers in a comprehensive
upgrade of its switching infrastructure to deliver resilient 10
Gigabit Ethernet services to its customers. The Force10 TeraScale
E-Series will allow DE-CIX to seamlessly scale its network to support
an anticipated 200 Gigabits per second (Gbps) of traffic by next year
as well as additional future growth.

"Our sustained throughput of 84 Gbps grew roughly 30 percent in
the last three months, and we need a network infrastructure that can
keep up with that growth while allowing us to scale our 10 Gig
services to meet customer demand," said Harald Summa, CEO of DE-CIX.
"By replacing our existing infrastructure with the Force10 E-Series,
we know we have a resilient network that can take us through the
transition to 100 Gigabit Ethernet without impacting our customers."

DE-CIX is leveraging the industry leading density of the Force10
TeraScale E-Series to build out a resilient, high performance network
that will deliver scalable Gigabit and 10 Gigabit Ethernet peering
services to its growing customer base. The TeraScale E-Series connects
nine colocation facilities throughout Frankfurt in a resilient 10
Gigabit Ethernet backbone to support more than 190 providers from more
than 20 countries. Supporting 1,260 Gigabit and 224 Ten Gigabit
Ethernet ports, the TeraScale E1200 provides the density DE-CIX needs
to increase its 10 Gigabit Ethernet services and seamlessly scale its
customer base to 230 by next year.

The patent-protected five Terabits per second (Tbps) backplane of
the Force10 TeraScale E-Series is uniquely architected for high
performance networks like DE-CIX that are currently processing high
traffic levels and anticipate rapid growth in the future. With up to
330 Gbps per slot, the TeraScale E-Series is ready to support 100
Gigabit Ethernet without the expense of a chassis or backplane
upgrade.

"DE-CIX is experiencing phenomenal traffic growth driven by
traditional data services as well as new bandwidth-intensive music and
video applications," said Mark Cooper, senior vice president of
worldwide sales at Force10 Networks. "The Force10 TeraScale E-Series
was designed to deliver long-term investment protection to customers
by providing a reliable, high performance network and enabling a
seamless transition to 100 Gigabit Ethernet."

Internet exchanges around the world are using the Force10
TeraScale E-Series at the core of their networks to deliver resilient
Gigabit and 10 Gigabit Ethernet services to their customers. In the
U.S., Equinix and Terremark have both deployed the TeraScale E-Series
to connect hundreds of customers within their exchanges. In Europe,
LIPEX is providing peering services while JPIX is connecting Internet
service provider throughout Japan with the TeraScale E-Series.
