Tokyo Institute of Technology Picks Juniper Networks for 10 Gigabit Campus

Seamless Multi-site Network Integrates Switching, Routing and Security with a Single Operating System

JAPAN, Nov. 22, 2010 — Juniper Networks (NASDAQ:JNPR, news, filings) today announced that the Tokyo Institute of Technology, the country’s largest and most prestigious science and technology university, has migrated its multi-site campus network to a robust high-performance infrastructure running the Junos® operating system. Deployment of Juniper Networks EX Series Ethernet Switches, together with Juniper routing and security devices, has increased network performance by an order of magnitude, with 10 Gigabit Ethernet connections to every building on the Institute’s three campus sites.

With around 13,000 students and staff engaged in a wide range of data-intensive science and engineering disciplines the Institute needs a high-performance network to support its research and educational activities. Its previous infrastructure could only support Gigabit Ethernet connections between customer devices and the network edge, a constraint which was becoming intolerable.

“We needed 10 Gigabit Ethernet to connect the customer devices with the network edge at the buildings. We also wanted to introduce a simplified network topology while providing a large number of access ports within our teaching labs. We selected Juniper Networks EX series for core and edge switching because of their high port densities,” said Katsuyoshi Iida, associate professor at the Global Scientific Information and Computing Center of the Tokyo Institute of Technology.

Juniper Networks EX8200 Ethernet Switches were selected as the Institute’s core switches because of their ability to provide wire-rate 10 Gigabit Ethernet ports. The port density of the EX8200s not only supported 10Gbps connections to all campus buildings but enables the Institute’s server farm to be directly connected to the switching core, further enhancing network performance.

Within the buildings EX4200 switches in Virtual Chassis configurations provide plenty of access ports with sufficient 10 Gigabit up-links for direct connection to the core, eliminating the cost and complexity of a network aggregation layer, greatly simplifying management and improving latency. Up to 10 Juniper Networks EX4200 Ethernet Switches can be connected through a high-capacity backplane in a virtual chassis configuration that is managed as a single device providing up to 480 access ports.

“Tokyo Institute of Technology now has a state-of-the-art campus network as befits one of the world’s leading science and technology universities,” said Yoichi Hosoi, vice president, of Juniper Networks, Japan. “It is very much a showcase for the benefits of network simplification which is one of the keys to a new network. The Institute will also greatly benefit from the fact that, with the Junos operating system, all network elements are orchestrated into an integrated security architecture that dynamically applies a consistent set of policies across the network.”

All the Juniper devices, including the EX Series Ethernet Switches, SRX Series Services Gateways and MX480 router, run the same Junos operating system which streamlines administration, helping meet the Institute’s goals for campus network reliability, performance, and manageability.
