World's Largest Broadband Service Provider Selects Juniper Networks for Core and Edge Network Expansion

Korea's KT Corporation To Deploy Both T640 Routing Nodes and ERX Edge Routers

Juniper Networks, Inc. (Nasdaq: JNPR), a leading provider of trusted infrastructures for the New Public Network, today announced that Korea's KT Corporation, the world's largest provider of advanced broadband services, has selected Juniper Networks T640 routing nodes and ERX Edge Routers as part of a major core and edge network expansion. Together, the two platforms provide KT with a fully integrated solution, with leading IP routing, Quality of Service (QoS), and Multiprotocol Label Switching (MPLS) capabilities.

With more than four million broadband subscribers, KT is the world's largest Internet Service Provider (ISP). With this deployment, KT's objective was to enhance performance and alleviate capacity demand throughout its nationwide network. After rigorous benchmark and network production testing, KT chose the T640 routing node for its high-port density, scale, and uncompromised dependability. The T640 routing nodes will aggregate Internet traffic through the Korea Internet Exchange (KIX)and Internet Data Center (IDC). Additionally, the T640 routing nodes offer a seamless path to multi-terabit scaling and allow for cost effective operational scale through reduced capital and operational costs.

Having already deployed the ERX routers in production networks for more than three years, KT purchased additional Juniper Networks ERX routers to help scale its growing subscriber base and to enable advanced wire-speed broadband services with subscriber-based IP QoS. The ASIC-based architecture of the ERX router combines necessary edge functionality, such as IP routing, subscriber management, and IP services. The wide range of interface options enables KT to deliver new, advanced Internet services such as Hotspots, Virtual Private Networks (VPNs), video-on-demand, video conferencing and online gaming.

"As the leading broadband services provider in the world, we needed to expand our network with routers that will scale our growing customer base and provide us with the necessary functionality to guarantee the delivery of innovative IP services," said J.C. Lee, director, Network Planning and Coordination Group, KT Corporation. "With the combination of ERX routers and T640 routing nodes, Juniper Networks provides us with the required technology."

"KT Corporation leads the world in broadband innovation," said Adam Judd, vice president, Asia Pacific Sales, Juniper Networks, Inc. "KT's selection of both the T640 routing node and the ERX Edge Router is a resounding endorsement of Juniper Networks integrated best-in-class edge and core routing solution. These deployments provide solid testimony to our commitment to the satisfaction of each of our customers and our focus on delivering next generation IP networks."
