Juniper Networks Drives Japan’s Ultra Fast and Flexible SINET4

National Institute of Informatics to Deliver Virtual Development Platform with Junos SDK

TOKYO, Japan, June 3, 2011 — Juniper Networks (NASDAQ:JNPR, news, filings) today announced that the Science Information Network (SINET), which connects more than 700 universities and research institutions throughout Japan, has migrated to a next-generation backbone designed to efficiently handle demand for increasingly higher amounts of bandwidth, services and users. SINET4 leverages the power of Juniper Networks® MX Series 3D Universal Edge Routers, the Junos® operating system and Junos Software Development Kit (SDK) to deliver dynamic network services and significantly improved performance, with increased capacity and higher interface rates, to a larger number of institutions.

SINET is primarily used for research applications requiring massive file transfers and ultra-high-speed in areas such as high-energy physics, nuclear fusion science, space and astronomical science, genome analysis, nanotechnology research, simulation sciences, and grid computing. It is also connected to other high-speed research networks, such as Internet2 in the U.S. and GÉANT2 in Europe, to support international research collaboration.

“High-speed networking for academic research is always at the leading edge because for some researchers there is no such thing as enough performance or bandwidth,” said Shigeo Urushidani, Professor of the National Institute of Informatics (NII), which manages SINET. “To achieve the goals set out for SINET4 we needed a routing infrastructure that was both more scalable and more dynamic in terms of service delivery. The Juniper Networks MX Series provides us with multidimensional scalability to keep growing bandwidth, services and users while the Junos SDK enables us to develop and create more dynamic network applications.”

SINET4 adds to the multiple network Layer 1, 2 and 3 services that were provided by SINET3 while paving the way for resource-on-demand delivery and the introduction of higher-layer services. Researchers at the National Institute of Informatics are using the Junos SDK to build and evaluate network applications on each virtual slice that leverage the power of Junos to orchestrate dynamic configuration changes across the SINET4 backbone infrastructure.

“SINET4 is a real showcase for Juniper Networks’ silicon and software technologies that go into making the new network,” said Mike Marcellin, vice president of marketing and business strategy, Juniper Networks. “Junos is the key since it provides a programmable, integrated approach to network design, creating a consistent cross-network platform that enables NII to innovate a new generation of dynamic network services with the Junos SDK.”

At the heart of SINET4, Juniper Networks MX960 3D routers have been deployed at eight points-of-presence across the country, including super nodes in Tokyo and Osaka. With 2.6 Tbps per router, the MX960s provide a foundation for massive scalability and support for wire-speeds up to 100Gbps. They are configured with Juniper Networks Multiservice Dense Port Concentrators, which simultaneously enable a broad range of applications and services, such as advanced IPsec, J-Flow accounting and tunnel services.
