Zen Internet Delivers High-Performance Hosting Enabled by Juniper Networks

UK ISP Deploys EX Series Ethernet Switches to Create Reliable, Scalable and Cost-effective Data Center Infrastructure

SUNNYVALE, Calif., June 30, 2009 - Juniper Networks, Inc. (NASDAQ: JNPR), the leader in high-performance networking, today announced that Zen Internet, one of the UK's premier independent Internet Service Providers (ISPs), has selected Juniper Networks EX Series Ethernet Switches to create a streamlined, cost-effective and manageable data center infrastructure that delivers the reliability and scalability required to support Zen's growing number of business customers.

"Zen Internet's reputation for fast and reliable hosted services is critical to our business," said David Barber, senior product manager, Hosting at Zen Internet. "We recognized the need to enhance our existing switch infrastructure in order to further improve the customer experience and our competitive edge. As an existing user of Juniper's high-performance networking infrastructure, Zen Internet was confident that Juniper could deliver a best-in-class switch solution for our data centers. The combination of EX Series switches and JUNOS® Software provides an open and flexible platform with a reduced long term total cost of ownership."

The Juniper Networks EX4200 line of Ethernet switches with Virtual Chassis technology combine the High Availability and carrier-class reliability of modular systems with the economics and flexibility of stackable platforms. Offering a full suite of Layer 2 and Layer 3 switching capabilities as part of the base software, the EX4200 line of switches satisfies a variety of high-performance applications, including branch, campus and data center access deployments as well as Gigabit Ethernet aggregation deployments. A single 24-port or 48-port switch can be deployed initially; as requirements grow, Virtual Chassis technology allows up to 10 EX4200 switches to be interconnected over a 128 gigabit-per-second (Gbps) backplane and managed as a single device, delivering a scalable, pay-as-you-grow solution for expanding network environments. By supporting a large number of high-performance ports in a compact form factor, the EX4200 switches with Virtual Chassis technology enable enterprises to reduce the number of managed devices and collapse or eliminate switching layers in the network infrastructure, dramatically reducing capital and operational expenses.

Zen Internet is a long-standing Juniper Networks T Series core router customer, and because the EX4200 switches leverage the same JUNOS Software - a single source operating system integrating routing, switching, security and network services from Juniper - Zen will benefit from the operational simplicity and increased efficiency which results from using a consistent operating system in multiple portions of its network. According to commissioned independent research*, JUNOS Software can dramatically reduce operating costs and complexity by up to 41 percent.

"Zen Internet delivers fast, reliable and secure services without compromise, and requires a network infrastructure with the same qualities," said Gert-Jan Schenk, senior vice president of operations, EMEA, Juniper Networks. "By innovating its data center infrastructure with Juniper's EX Series switches, Zen Internet has created a service-enabling network infrastructure that can drive network monetization."

Winner of the UK consumer watchdog Which? Best Broadband 2008 award and PC Pro Magazine's Best ISP of 2008, Zen Internet delivers a wide range of high-quality, high-speed broadband services to business and residential customers across the UK. From the latest in high-speed DSL broadband Internet access, leased lines, Voice, IP VPN and complete Web hosting packages to state-of-the-art Web site design and managed network security, Zen Internet's network delivers fast, reliable and secure services.
