KDDI America Deploys Juniper Routing and Switching Solutions to Extend Ethernet Services to U.S. Market

Global Leader in Ethernet Leverages Performance and Flexibility of EX and MX Series to Deliver High Speed, Scalable Business Services

NEW YORK and SUNNYVALE, Calif., June 17, 2009 - Juniper Networks, Inc. (NASDAQ: JNPR), the leader in high-performance networking, and KDDI America, the U.S. division of KDDI Corp., a Global Fortune 500 company and worldwide leader in international telecommunications services with over 50 years of service to the global community, today announced KDDI America has selected Juniper Networks Carrier Ethernet solution for entry into the U.S. market. The EX Series Ethernet Switches and MX Series Ethernet Services Routers provide superior scale, density and flexibility, enabling KDDI America to rapidly deliver high-quality services while reducing total cost of ownership (TCO).

"Businesses in the U.S. are looking for high-quality services that offer the potential cost savings and simplicity of Ethernet, so this is a great time for us to introduce our nationwide Ethernet service," said Hokuto Sanematsu, director of Network Engineering, KDDI America. "The flexibility, scalability and efficiency of the Juniper switching and routing solutions enable us to expand into new markets with scale to meet growing demand while fueling profitable growth and reducing TCO."

KDDI is a widely recognized global leader in the development and provisioning of Ethernet services, most notably in Japan - where its award-winning service possesses the largest market share* - and throughout the wider Asia-Pacific region, with service to the United States via points of presence in New York and Los Angeles. The outstanding performance of their services, with realized availability of over 99.999 percent, prompted a large number of U.S. corporations already using KDDI's Ethernet connectivity internationally to request service of similar quality in North America. With the comprehensive Juniper solution, KDDI America is now able to seamlessly fulfill those needs.

KDDI America will be deploying the MX Series routers in the core of its network and the EX Series Switches for aggregation and customer access. The MX Series is a family of Ethernet Services routers with powerful Layer 2 and Layer 3 features designed for high-performance service providers and enterprises. Consisting of the MX960, MX480 and MX240, the MX Series Ethernet Services Routers provide high port-density routing and switching in a range of highly efficient, high-performance hardware platforms, enabling service providers to reduce power, space and cooling costs by as much as 50 percent. The EX4200 line of Ethernet switches with Virtual Chassis technology combine the High Availability (HA) and carrier-class reliability of modular systems with the economics and flexibility of stackable platforms by enabling up to 10 interconnected switches to be operated and managed as a single logical device.

The EX and MX Series both run JUNOS® Software, a single source operating system integrating routing, switching, security and network services from Juniper Networks. By running a single, consistent operating system in many portions of its network, network operators can dramatically reduce operating costs and complexity by up to 41 percent, according to third-party research.

"KDDI has a wealth of experience delivering Ethernet services in many markets around the world, and we are pleased to be working with them as they extend this experience and technology to the U.S. market with the same high quality experienced by their international customers," said Dr. Mallik Tatipamula, vice president and head of wireline, wireless and managed services segments, Juniper Networks. "By selecting a high-performance, service-enabling infrastructure consisting of JUNOS-based switching and routing platforms, KDDI America will be able to deliver high-quality services with maximum choice and flexibility - monetizing their network by increasing service revenues while driving down costs."
