Juniper Networks New T-series Family Delivers Breakthrough in Core Routing Technology and Provider Economics

Juniper Networks T640 Internet Routing Node with Matrix Technology Selected by Verio, France Telecom Research and Development, the National Science Foundation's TeraGrid Project and the Internet2 Abilene Network

Sunnyvale, CA - April 23, 2002 - Juniper Networks, Inc. (Nasdaq: JNPR), a leading provider of trusted infrastructures for the New Public Network, today announced the new Juniper Networks T-series Internet routing family, including the introduction of the T640 Internet Routing Node. Incorporating Juniper Networks new Matrix Technology, this groundbreaking development enables service providers and carriers to build more profitable Internet Protocol (IP) networks by extending the lifespan of today's investments much further into the future. The T640 platform is already deployed worldwide at locations including Verio, France Telecom Research and Development and the National Science Foundation's TeraGrid Project. It has also been selected for the next-generation Internet2 Abilene network.

Based on Juniper Networks third generation of high-density silicon, the new T-series platform enables a breakthrough in service provider economics. It offers seamless multi-terabit scaling, while significantly reducing capital and operational costs. In a stand-alone configuration, the T640 Internet Routing Node supports 32 OC-192c/STM-64 ports in a half-rack chassis, and offers eight 40 gigabits-per-second (Gbps) slots. With bandwidth density greater than four times that of the nearest competitors, the T640 platform redefines core routing. From the very largest cores down to small- and medium-sized Points of Presence (POPs), the T640 Internet Routing Node provides substantial investment protection by enabling service providers to scale their networks seamlessly in line with demand.

For the first time, service providers and carriers can seamlessly scale their high-speed IP networks to multi-terabit capacities. "With demands on our network increasing nearly 100 percent year over year, we needed an IP-routing solution that would scale easily over the next five years. The new Juniper Networks T640 platform offers us this long-term cost of ownership advantage, while enabling us to lower capital costs, simplify operations and provide a high degree of investment protection," said Michael Stewart, president of Verio's broadband services business unit.

Continuing a tradition of network innovation, the new Juniper Networks Matrix Technology provides for a two-way architecture that overcomes the scaling limitations of existing low-density routers to deliver a two to threefold increase in network asset lifespan. The T640 Internet Routing Node enables 640 Gbps through the customer-facing ports and provides for 1280 Gbps through the rear of the chassis via an optical backplane extension. This nonblocking, any-to-any, multichassis configuration enables multiple T640 Internet Routing Nodes to interconnect and operate as a single router, while preserving valuable revenue-generating ports. The Juniper Networks Matrix Technology will enable eight or more T640 Internet Routing Nodes to be connected in an Internet Routing Matrix to deliver 10 or more terabits of throughput, split equally between the front-panel Wide Area Network (WAN) ports and the matrix optical backplane extension.

"Two of our hubs require 10 to 14 OC-192 connections from the beginning and with the anticipated growth in performance and additional sites and hubs, it is essential we have a highly scalable solution with proven software support," said Linda Winkler, TeraGrid network architect, Argonne National Laboratory. "The Juniper Networks T640 platform with JUNOS Internet software provides the most comprehensive combination of performance, functionality and seamless scalability available today."

"With over 200 of the leading U.S. research universities and laboratories using the Abilene network to meet their advanced networking requirements, we need a platform that provides support for scalable, high-performance Internet Protocol version 6 (IPv6), multicast and gigabit-per-second unicast flows," said Steve Corbató, director of backbone network infrastructure for Internet2. "Our stringent testing concluded that the Juniper Networks T640 platform best meets our needs today and provides us with the cost-effective scalability we will need to meet our aggressive future requirements."

JUNOS Software Scales Seamlessly to Support Multi-terabit Throughput

Juniper Networks proven and trusted JUNOS software scales seamlessly from the existing M-series platforms to the new T-series family via a single software image. Service providers and carriers continue to benefit from the feature consistency between and across all platforms, and the same service richness they are used to. With native JUNOS software support for multiprotocol label switching and hardware-based IPv6 forwarding, the T640 Internet Routing Node provides a flexible and dependable platform for a wide range of services from Private IP and 2.5G/3G mobile, to asynchronous transfer mode (ATM) and Frame Relay migration. The comprehensive security features of JUNOS software are also available in the T-series family. The Juniper Networks tradition of providing carrier-class dependability is continued with the latest T-series family.
