Japan's HOTnet Selects Juniper Networks for New 10-Gigabit MPLS Network

M- T- and E-series Platforms Deployed To Provide Advanced IP Services

SUNNYVALE, Calif., November 11, 2003 - Juniper Networks, Inc. (Nasdaq: JNPR) today announced that Japanese service provider, Hokkaido Telecommunications Network Co. (HOTnet), is transforming its regional wide area network to a 10-Gigabit Multiprotocol Label Switching (MPLS) architecture based on routing platforms from Juniper Networks.

HOTnet will launch a range of sophisticated revenue-generating services, including QoS-controlled Layer 2 and Layer 3 VPN services, and is developing an MPLS-based Internet Exchange (IX) using Juniper Networks M-, T- and E-series platforms.

"Our vision is for a network infrastructure that seamlessly connects from the core to the edge and delivers reliable and highly scalable services," said Satoshi Baba, manager IT Expert and Technical Planning for HOTnet. "Juniper Networks routing platforms are enabling this evolution. For example, the M-series platform's hardware-based MPLS functionality and robust QoS facilities provide for a wide range of network services and an easy transition from our legacy dedicated services to new L2 and L3 services."

A member of the PowerNets Japan group of 10 power companies, HOTnet was an early leader in its market with its Gigabit Ethernet LAN to LAN (L2L) service. The new MPLS network will meet growing demand for highly reliable services, especially from users relying on mission-critical business networks.

HOTnet is also using the M-series as a high-performance IX routing platform. It has also replaced its legacy broadband aggregation equipment with Juniper Networks E-series platform, planning to leverage its capabilities to provide voice over IP (VoIP), content distribution and other highly customized services. In addition, Juniper Networks T-series high-density routing platform has been selected to provide the high reliability and scalability essential to HOTnet's MPLS backbone and to serve as the basis of a possible network enhancement to GMPLS.

"HOTnet is recognized across Japan as a market leader in the deployment of advanced network services," said Masanori Osuga, vice president, Japan, Juniper Networks. "We are excited about the potential of the new HOTnet MPLS network using best-in-class Juniper Networks solutions to provide the next generation of advanced commercial IP services to business and residential users of Hokkaido."
