Juniper Networks Ships the Industry's First Internet Backbone Router Delivering Unrivaled Scalability, Control and Performance

First Wire-Speed OC-48 Router in Acceptance Testing with MCI WorldCom, UUNET WorldCom, and Verio

Mountain View, CA - September 16, 1998 - Juniper Networks, Inc. today debuted the M40, the industry's first shipping Internet backbone router to deliver Internet scale, Internet control and unparalleled performance in a single system. The M40 is a new generation of routing device designed to handle the unique network control and reliability demands of the evolving optical Internet. Currently shipping, the M40 is in acceptance testing with leading Internet Service Providers (ISPs), including MCI WorldCom, UUNET WorldCom, and Verio.

The M40 shipping announcement culminates months of successful testing of the JUNOS software and the M40 system, underscoring the exacting technical and time-to-market standards met by the M40 and the strength of the Juniper Networks company franchise. The JUNOS software began extensive testing in lab and live Internet environments with the world's leading ISPs in December, 1997. Reflecting the maturity of the M40's leading-edge ASIC design, the system was up and running immediately upon receipt of the chipsets. With the company's unique blend of best-of-class Internet protocol experts and leading-edge ASIC development talent, coupled with well-credentialed service, support and manufacturing teams, Juniper Networks is poised to continue to provide unrivaled advances to the reliability of the Internet.

"We've been consistently impressed with Juniper Networks experience and their track record of delivery, and the latest M40 system is no exception," said John W. Sidgmore, CEO UUNET WorldCom and Vice Chairman & COO MCI WorldCom, Inc. "This company really understands the Internet and the way market focus drives system design to meet ISP's daily operational needs."

The M40 is the first platform to integrate the performance formerly found only in switches with the rich, software-enabled control of routing and features a number of breakthroughs in ASICs-based packet processing, Internet routing and traffic engineering. The Juniper Networks Internet Processor is the most advanced packet look-up engine ever implemented on a router platform and provides industry-leading packet look-ups of 40 Mpps (million packets per second) using a switch fabric that operates at 40 Gbps.

The M40's powerful packet processing is supported by the system's separate routing, control and traffic engineering capabilities provided by the JUNOS software, the industry's first Internet-optimized routing operating system. Finally, by providing the industry's first wire-speed OC-48 interfaces, the most flexible combination of interface speeds available and the highest port density per-rack inch in the industry, the M40 gives Internet backbone service providers complete design and configuration flexibility as they migrate to higher-speed backbone networks.

"Juniper Networks has focused from the start on solving the problems of today's fast-growing Internet. We have built a company, key partnerships, and a first of its class Internet router with the infrastructure to support it," said Scott Kriens, president, CEO and chairman of Juniper Networks. "Because of this, we are able to deliver the first of a critically needed new generation of routers to ISPs from a company that can scale with the Internet."

The PFE and Internet Processor: Extensible, Best-in-Class Forwarding Performance

At the core of the M40 router is the powerful Packet Forwarding Engine (PFE) driven by state-of-the-art ASICs manufactured by IBM. Featuring a single, shared memory system, the PFE has one forwarding table, one look-up, one packet write and one packet read. The ASIC-based PFE architecture allows ISPs to provide key, differentiated service creation features through CoS (Class-of-Service) applications, multicast and traffic engineering. The highly integrated ASIC design ensures minimum space and power consumption.

"IBM was pleased to support the Juniper team in their development of such an advanced ASIC design," said Bruce Beers, director of ASIC Products for the IBM Microelectronics Division. "As a leading provider of complex ASICs, we were able to complement Juniper Networks communications system design talents with our tools, methodologies and process technology. One of IBM's central strategies is to enable e-business, in part through enhancements to Internet technology. It has been exciting to see how rapidly the innovative Juniper Networks design team has been able to use our technology to create new infrastructure products which support electronic commerce."

The greatest innovation of the M40 PFE is the Internet Processor, which is the fastest and most flexible route look-up engine available, delivering 40 Mpps or 100 times the look-up capability of existing look-up engines used in routers in the Internet today. The Internet Processor is a fully programmable look-up engine, providing not just performance but allowing ongoing software evolution. While initial protocols implemented include IPv4, Multi-Protocol Label Switching (MPLS) and IP multicast, the Internet Processor allows complete extensibility with new Internet protocols easily programmed through software rather than expensive hardware modifications.

The Internet Processor also provides critical network performance insurance to service providers by ensuring that routing and forwarding performance are operating at optimal levels. With the Internet Processor, performance scalability is ensured, regardless of the size of the forwarding table or the length of the look-ups.

By supporting atomic updates which quickly translate routing changes to the forwarding table, the Internet Processor maintains full forwarding rates even while a network is undergoing high levels of routing change. Finally, the Internet Processor gives service providers complete visibility into the system performance through traffic sampling and traffic trends analysis.

JUNOS: Reliable Traffic Engineering and Control

For maximum Internet control and reliability, the M40 features JUNOS software, the first and only routing operating system designed for Internet control. The JUNOS software offers a complete set of Internet-tested, Internet-scale and standards-compliant routing protocols for optimal management of network growth and operations. The JUNOS software ushers in a new level of network control and efficiency through the industry's first implementation on an Internet backbone class router of the emerging Multi-Protocol Label Switching (MPLS) traffic engineering standard. In addition, the JUNOS MPLS provides ISPs with a solid framework for adding new and differentiated services to their backbone offerings.

The unique, modular, protected memory design of the JUNOS software provides service providers with greater reliability and facilitates faster introduction of new features. The JUNOS protected, modular design improves reliability by ensuring that modifications made to one module do not adversely impact other sections of the software. Separate, clean modules also facilitate software development and faster deployment of new features.

Optimal Design and Configuration Flexibility

Offering the highest port density-per-rack in the industry at ten times the performance density of current offerings, the M40 ensures optimal use of valuable and scarce Point-of-Presence (POP) rack space. The system's small footprint enables two units to be stacked in a standard rack, while drawing less than 1 amp of power per rack inch. In addition, the M40 boasts the most flexible combination of backbone interface speeds available, offering 32 slots for complete mix-and-match integration. Eight flexible Physical Interface Cards (PIC) Concentrator (FPC) boards support a wire-rate OC-48 interface as well as various combinations of OC-12, OC-3 (Synchronous Optical Network - SONET and Asynchronous Transfer Mode - ATM) and DS3 interfaces, allowing different interface types and speeds to be combined on a single FPC.
