Architecture and Key Components
Juniper Networks T Series routers support the features that
service providers need to handle today’s massive growth in
core bandwidth requirements. These features include MPLS
Differentiated Services (DiffServ-TE), point-to-multipoint label-
switched paths (P2MP LSPs), nonstop routing, unified in-service
software upgrades (unified ISSUs), hierarchical MPLS, and service
delivery with the Juniper Networks JCS1200

T Series routers enable service providers to deliver stringent
quality of service (QoS) and meet SLAs for multiservice transit
and IP services. In addition, Juniper’s industry-leading IP/MPLS
capabilities guarantee that the service level and performance
of critical services are maintained while extending the effective
lifespan of legacy network assets. The T Series is ideal for creating
network infrastructures that must scale to meet constantly
growing Internet traffic for all types of applications. Furthermore,
capacity-based power consumption for all T Series routers is the
lowest in the industry. Table 1 illustrates the scaling characteristics
of the T Series single chassis routers.

T640 Routing Platform
At 19 inches wide and a half rack in height, Juniper Networks
T640 Core Routers address the need for highly scalable, high-
performance core routing at a fraction of the size of competitive
offerings. Each of the eight slots in the T640 delivers 40 Gbps
with the ability to scale well beyond that capacity, fulfilling the
need for the high bandwidth services of today and tomorrow.

performance core routing at a fraction of the size of competitive

with the ability to scale well beyond that capacity, fulfilling the
need for the high bandwidth services of today and tomorrow.
The T640 supports up to 8 OC-768c/STM-256 ports, 40 10 Gbps
ports (10GbE or OC-192/STM-64), 128 OC-48c/STM-16 ports, and
an industry-leading 320 1GbE ports. It delivers up to 640 Gbps of
capacity with the ability to forward up to 770 million packets per
second (Mpps). The T640 also supports lower speed interfaces,
providing added flexibility to combine high-speed core routing
with dedicated access aggregation in a single platform.

T1600 Routing Platform
Also at 19 inches wide and a half rack in height, the multichassis
capable Juniper Networks T1600 Core Routers address the need
for highly scalable, high-performance core routing at a fraction
of the size of competitive offerings. The T1600 delivers up to 1.6
Tbps of capacity (100 Gbps/slot) with the ability to forward up to
1.92 billion pps.

Juniper provides unique capabilities for upgrading T Series routers
to accommodate the changing requirements of service providers.
For example, the T640 can grow in-service into a T1600 by only
replacing the power module and switch fabric. Following such an
upgrade, the T1600 provides more than double the capacity of
T640, while only using fractionally more power.

The packet forwarding and switching complex of a T1600

T4000 Routing Platform
Juniper Networks T4000 Core Routers are the highest capacity
half rack routers in the T Series family, extending Juniper’s proven
history of innovation and investment protection. The T4000
system more than doubles the per-slot capacity of existing T1600
systems from 100 to 260 Gbps—and with only 25% increase
in power. Existing T640 and T1600 systems can be upgraded
in-service to a T4000 system, offering ultimate investment
protection for a T Series installed base.

A fully loaded T4000 system can support up to 208 ports of
10GbE, or 16 ports of 100GbE interfaces, making it the densest
line-rate IP/MPLS routing system. With a pay-as-you-grow model,
service providers can migrate in-service and scale a single T4000
from 4 Tbps chassis to a multichassis configuration with the
TX Matrix Plus to support up to 16 Tbps
