Juniper networks T4000 User Manual

The worldwide growth in Internet

trac continues unabated. Although

video applications account for the

largest portion of this growth, other

big drivers are mobile and emerging

social applications. In a networked

economy, the quality of connectivity

impacts business performance. Carriers

must translate this dependence into

profitability, which means finding

new ways to lower costs on existing

services, developing new revenue

generating services, and evolving

business models to the changing

network landscape.

The T4000 Core Router provides the

scalability and flexibility required to

meet this diverse set of requirements.

With rich service processing, the

industry’s highest per-slot throughput

of 240 Gbps, and in-service hardware

upgrade capability, the T4000 is the

ideal service provider platform, oering

unprecedented investment protection

and operational economics to

profitably manage a core infrastructure.

FACT SHEET

T4000 CORE ROUTER

Product Description

The Juniper Networks® T4000 Core Router is the next generation of T Series routers,

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 Gbps

to 240 Gbps—and with only 25% increase in power. A fully loaded T4000 system can

support up to 192 ports of 10GbE, or 16 ports of 100GbE interfaces, making it the densest

line rate IP/MPLS routing system. The T4000 is a true multiservice core system that is

designed to deliver a reliable, high-performance, and flexible architecture to carry a wide

breadth of services over a common IP/MPLS infrastructure.

With four terabits of line rate throughput in a half rack chassis, the T4000 offers double

the slot capacity of the nearest competitor. In addition, all existing T640 and T1600

systems can be upgraded in service to T4000 systems, offering ultimate investment

protection to the existing T Series installed base.

T Series routers enable service providers to deliver stringent quality of service (QoS) and

meet service-level agreements (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 life span

of legacy network assets. The T Series is ideal for creating routed infrastructures that

must scale to meet constantly growing Internet traffic for all varieties of applications.

Furthermore, capacity-based power consumption for all T Series routers is the lowest in the

industry. The following table illustrates the scaling characteristics of the T Series family.

T320 320 Gbps 1/3 rack

T640 640 Gbps 1/2 rack

Network Virtualization

Hardware virtualization enables operators to consolidate networks (corporate and

residential) and nodes (core and aggregation) onto a single simplified infrastructure.

The result is high CapEx and OpEx savings, secure administrative isolation between

services, and rapid introduction of new services. The T4000 system along with the Juniper

Networks JCS1200 Control System—the industry’s first purpose-built, control plane

scaling platform—will continue to provide operators the flexibility of consolidating or

separating network components based on their service needs.

Architecture and Key Components

The core network is the heart of any next-generation network or

multiplay deployment. With the growth of distributed content

in metro networks, and emerging video, social networking, and

mobile applications, the core network must deliver high-speed

transport at five 9s reliability, and, at the same time, provide rich

service delivery features. The T4000 system offers providers the

premier core routing option in the industry—an ultra high capacity

core with the ability to support hardware virtualization. Juniper

Networks Junos

resilient, high-performance, and flexible applications for backbone

carriage of content-intensive consumer and business traffic.

High Availability

The T Series architecture allows all Junos OS features and

services to operate across many interface types without

compromising performance. From its inception, Junos OS was

®

operating system functionality offers the most

developed for rigorous service provider needs. For example,

Junos OS is completely modular so that in the unlikely event

one module experiences a problem, it is isolated to that specific

section of code and does not bring down an entire system. On the

hardware side, all major components—including Routing Engines,

Control Boards (CBs), Switch Interface Boards (SIBs), and Power

Equipment Modules (PEMs)—are redundant.

In-Service Hardware Upgrade

One of the key architectural choices in the T Series family of

routers is the nondisruptive hardware upgrade. Juniper provides

unique capabilities for upgrading existing T640 and T1600

routers to T4000 routers. Following such an upgrade, the T4000

provides more than double the capacity of T1600, while only using

about 25% more power. The steps highlighting such an upgrade

procedure are shown in Figure 1 below.

Four easy steps to perform a
service hardware upgrade:

1. Upgrade Power Entry
Modules (PEMs)

2. Upgrade Switch Interface
Boards (SIBs)

3. Fix new face panel

4. Upgrade fan

provides the largest variety of interfaces in the densest
form factor among core routing platforms.

T4000 scale and density features allow service
providers to increase capacity without adding additional
systems to the network.

HA and continuous operation is critical in core routing,
where loss of a single routing node can remove service
for a wide geographical area.

HA requirements in core networks include the
elimination of planned downtime, giving the benefit
of better network stability, easier operations, and less
operational risk.

Features such as highly granular QoS, advanced filter­based forwarding, and flow-based monitoring are a key
component for providing wide ranging services on a
single network.

Combining the functions of previously disparate
network elements oers greater network simplicity, and
retains the service building advantages of the overlay
networks being replaced by the converged network.
