SUNNYVALE, Calif., April 21, 2008 - Juniper Networks, Inc. (NASDAQ: JNPR), the leader in high-performance networking, today announced that Korea's Hanaro Telecom has scaled network capacity with Juniper Networks T-series core routers. Traffic growth, driven by increased subscriber demand for IPTV and other multiplay services, compelled Hanaro to increase capacity with Juniper Networks T-series, which offer a unique, non-disruptive upgrade path to multi-terabit capacity. Hanaro selected the T-series for its superior investment protection, low total cost of ownership and the proven stability and rich feature set of Juniper's JUNOS software.

"We are leveraging the rich feature set of JUNOS and the high performance of the T640 chassis to address growing traffic demand," said Bongki Kang of Hanaro's Backbone Network team. "The T-series router's inherent reliability, and ability to scale seamlessly, gives us the confidence that we will meet our customers' increasing demand for innovative new services."

With over 4,000 platforms shipped to more than 200 customers worldwide, the T-series is the industry's most proven, scalable, feature-rich, and flexible core routing platform with the scale, performance, reliability and security required by the world's most demanding IP networks. All Juniper Networks T-series routers leverage JUNOS, a single source operating system that enables consistent operations, network scale without disruption, and unprecedented interoperability and service agility.

"South Korea's adoption of advanced IP services such as IPTV continues to grow at an impressive rate," said Tim Kang, Juniper's vice president of Korea. "Service providers such as Hanaro Telecom require a clear path to scalability, with minimal service interruption, overhead, or capital outlay. We are pleased to provide Hanaro with a service-enabling network infrastructure based on the T-series that helps expand and accelerate service model innovation, fueling business growth."
