1. INTRODUCTION
1.1 Juniper Networks : Technology Overview
1.1.1 Challenge: Reliability with Rapid Growth
Internet backbone networks are constantly under pressure to scale rapidly in
order to accommodate customer demands for faster response times and greater
reliability. At the same time, routing and packet forwarding technologies have
lagged Internet growth. This lag has increased the operational challenge of
maintaining stability in the face of rapid network growth. As Internet backbone
networks move to ever-faster optical rates, a new generation of routing device is
required that can provide the necessary combination of optical-rate forwarding
and operational control to enable providers to scale their networks rapidly and
reliably.
1.1.2 Juniper Networks: Enabling IP Network Growth
With the delivery of the M-xxx Internet Backbone Routers and JUNOS Internet
Software, Juniper offers new levels of control and performance for Internet
Protocol backbone providers. A unique combination of best-in-class Internet
protocol developers and expert ASIC hardware designers will enable Juniper to
continue to deliver high-performance routing and forwarding systems that
address the scalability, performance, and reliability necessary to support the
Internet’s continuous and explosive growth. In addition, extensive experience in
manufacturing and supporting routing systems for fast-growing Internet protocol
backbone network providers gives Juniper a solid understanding of the scaling
challenges of the Internet and a unique ability to help IP network providers scale
to meet demand today and into the future.
Juniper’s Internet Software, JUNOS
TM
, offers best-of-class implementations of all
Internet routing protocols, including BGP4, OSPF, IS-IS, MPLS, and multicast.
The quality of the protocol implementations reflects the experience and expertise
of the developers, who all have taken active roles in defining and authoring
numerous Internet protocol drafts and RFCs (Request for Comments) in the IETF
(Internet Engineering Task Force), and who all have extensive experience in
writing and supporting code that forms the heart of the Internet. Juniper has the
experience base to understand both what is necessary to implement Internet
scale protocols and to support such protocols in a mission critical environment.
The Juniper software experts will continue to provide focused standards
leadership for the benefit of customers, who require a partner that understands
and can facilitate protocol implementations to scale at the Internet’s and large
enterprises’ existing growth rates.
1.1.3 M5, M10, M20, M40, M160 : Foundation for the Internet Core
The M-xxx Internet backbone routers from Juniper Networks have been designed
specifically for the specialized needs of high-growth Internet backbone providers,
featuring market-leading packet-forwarding horsepower, unparalleled port density
and port flexibility, and best-in-class Internet software. The M-xxx deliver the
speed required for providers to grow their backbones to OC-48 speeds, while
also providing the necessary traffic engineering tools to ensure greater control
over traffic and use of network capacity. In addition, the M-xxx make the most
efficient use of precious point-of-presence (POP) rack space, offering the highest
port density and highest performance per rack-inch on the market today. The M-
xxx low power consumption also offer best-in-class efficiency of POP power
consumption. Finally, to ensure rock-solid network stability, the M-xxx have been
engineered to handle the exceptionally stressful conditions that arise under peak
traffic loads and link failures.
The M160
™
Internet backbone router is the first routing platform of its kind,
offering true wire-rate performance for up to 16 OC-192c/STM-64 or 64 OC-
48c/STM-16 Physical Interface Cards (PICs) per rack. The M160
breakthrough ASICs translate optical bandwidth into new, differentiated IP
services. Running the same JUNOS
™
Internet software and delivering the
same services as the already proven M20
™
and M40
™
Internet backbone
routers, you can be assured of an efficient, easily scalable, end-to-end
solution when building out your infrastructure. The M160 platform is ideal for
large networks requiring predictable performance for feature-rich
