Top 10 Reasons to Choose the Juniper ON Enterprise Network

Juniper’s enterprise access products meet the

always-on needs of today’s enterprises by delivering

solutions that are reliable, simple, and smart.

The Juniper ON Enterprise Overview Today’s corporate enterprises are changing—changing quite

radically and very swiftly at that.

Just look at the numbers. Approximately half of all mobile phones

sold in Q1 2013 were smartphones.1 Correspondingly, the number

of mobile broadband subscriptions worldwide grew at a rate

of 45 percent between Q1 2012 and Q1 2013, reaching a total of

1.7 billion.2 Not surprisingly, global mobile data traffic growth is

projected to increase 13-fold to 11.2 exabytes between 2012 and

2017. This amounts to a 66 percent compound annual growth

rate (CAGR) in mobile data traffic.3 And mobile video will be the

main driver of this growth, according to Gartner.4

What does this mean for enterprises? For starters, your

users now expect ubiquitous, around-the-clock access to all

applications and network resources from the mobile device of

their choosing. Increasingly, they will expect video collaboration

and communication tools to work flawlessly on their mobile

devices as well. Companies are taking notice. Already, 42

percent of companies have bring-your-own-device (BYOD)

policies in place.5 However, it turns out that what a company

formally allows doesn’t really matter, since 67 percent of people

surveyed already use personal devices at work, regardless of their

company’s official BYOD rules.6 CIOs’ top priorities today all

revolve around improving the user experience,7 which raises the

question: Can enterprise networks deliver?

Welcome to today’s enterprise, where mobility technologies and

smart devices allow people to work from anywhere at any time.

As a result, the enterprise network needs to be always on and

always available to its users.

The Juniper ON Enterprise is a combination of wired, wireless, and

management solutions that provide a reliable, simple, and smart

network to extend the enterprise to any device and to any location.

It’s what’s needed to enable the always-on enterprise today.

Juniper networking products have been deployed across

industries for more than a decade. Juniper’s switching products

are in more 20,000 customer networks—both enterprise and

service provider. Today, more than 1 million Juniper access points

are installed at more than 6,000 enterprises worldwide. Juniper

wired and wireless solutions can be found in businesses of all

sizes, including Fortune 100, government, hospitality, financial

services, and retail institutions.

Top 10 Reasons to Choose the Juniper ON Enterprise NetworkJuniper delivers switching, wireless local area network (WLAN),

and network management solutions that enable employees to

leverage new tools that drive business in the enterprise. Below

are 10 of the most important reasons enterprises choose the

Juniper ON Enterprise to enable reliable, simple, and smart

access to mission-critical applications from any device and from

anywhere in the world.

1) Demand for unified access across wired and wireless

network infrastructures: Customers are looking to converge

their wired and wireless networks to alleviate increased

operational complexity, reduce costs, and bolster security.

Over previous decades, voice and data networks were

successfully converged to solve similar issues. Today, Juniper

has a complete access portfolio from core to the edge that

works seamlessly together. In the near future, Juniper will

provide converged wired and wireless on a core switch,

allowing direct exchange of wired and wireless data on the

most reliable platform.

2) High-density traffic: BYOD policies have created problems

for many enterprises, with too many people and too many

types of devices running too many applications. Enterprises

need WLAN solutions that are capable of supporting a large

number of sessions and are flexible enough to adapt to

shifting, highly dynamic traffic patterns. Juniper’s wireless

networks can handle a broad diversity and density of wireless

devices. Juniper’s wireless architecture can also dynamically

perform client load balancing and band steering to support

a higher density of clients, delivering the highest overall

system throughput with the least error and retry rates.

The wired network has to be able to handle the wireless

traffic patterns—and Juniper’s switches support increase in

bandwidth by being scalable and flexible enough to match

these growing requirements.

3) Operational simplification: IT and network administrators

are always seeking to simplify operations and management,

and reduce costs for their enterprise networks. They

need seamless integration of both wired and wireless

networks; a single-pane-of-glass management solution

for the entire enterprise; and flexible, reliable wired and

wireless deployments that satisfy the demands of BYOD

environments. Juniper’s Virtual Chassis technology

collapses up to 10 physical devices into a single logical

device, simplifying management of the network. Juniper’s

wireless architecture allows seamless management with

single touch moves and changes. Juniper Networks® Junos®

Space Network Director provides centralized, single-pane-

of-glass management capabilities across both wired and

wireless networks.

4) Flexible and simplified architecture: Juniper supports the

capability for enterprises to consolidate or collapse network

tiers, resulting in a simple switching architecture. Its Virtual

Chassis technology and MPLS ensures reliability despite

the collapsing of network tiers. These features also provide

enterprises with the flexibility to scale their network as their

business grows. On the wireless side, the ability to cluster

with Virtual Controller Cluster™ technology and Juniper’s

advanced data path architecture gives the enterprise flexible

deployment options. Enterprises can deploy controllers

entirely in the data center without losing features or

functionality at remote sites, realizing a more cost-effective

and manageable wireless LAN solution. They can choose

local switching, in which the access points act as switches to

eliminate the need for traffic to flow through the centralized

controller. Juniper Networks JunosV Wireless LAN Controller,

a software instance of Juniper’s wireless controller, delivers

all the functionality of the hardware appliance to offer even

more deployment flexibility. Juniper’s architecture gives

enterprises the flexibility to do what is best for their particular

business environment.

5) Resilience: Juniper provides the only hitless stateful failover

solution for zero impact network failover. When an unplanned

outage such as a power failure occurs, all wireless sessions on

a Juniper WLAN system seamlessly and statefully fail over to a

backup controller, with zero service disruption. This resilience

results from Jupiter’s Virtual Controller Cluster technology, an

extraordinarily cost-effective feature that allows enterprises

to establish redundancy by adding just one controller. In

contrast, competitive solutions require doubling the number

of controllers to achieve redundancy. On the wired side, MPLS

switching offers built-in resilience and failover mechanisms,

and Virtual Chassis technology increases the reliability of the

switched network. Juniper switches also support multichassis

link aggregation group (MC-LAG), nonstop active routing

(NSR), and graceful restart.

6) In-service software upgrades: Juniper provides the only

wireless LAN and wired systems that enable users to perform

in-service software upgrades on live networks. With many

enterprises supporting facilities across wide geographic

areas, coordination of software upgrades (for example,

alerting employees, scheduling downtime, etc.) is an

important requirement and can be a major challenge. When

an image upgrade is required on the wireless side, Juniper’s

WLAN system allows a centralized IT team to perform in-

service software upgrades with near zero interruption to

end-user service. Likewise, on the wired side, enterprises

don’t need to power down switches and take them offline

to perform maintenance or upgrades. All that can be done

while the switched network is up and running.

7) Simple expansion: Juniper enables enterprises to easily and

seamlessly expand both wired and wireless networks. On

wired networks, Juniper’s Virtual Chassis technology provides

the flexibility to stretch the network up to 80 kilometers or

add up to 10 switches into a single configuration. Whether

there is the need to expand across the campus or to a

different location, MPLS and VPNs provide the means to

stretch connections across sites. For WLANs, adds, moves,

and changes are completely automated and nondisruptive

to user sessions. Adding a controller to Juniper’s wireless

LAN system simply requires powering up the new controller

and giving it the IP address of the master controller. The

master controller downloads the full configuration, sets up

all real-time states, and seamlessly load-balances access

point capacity onto the new controller—all with no user

intervention. The network can be as flexible as the enterprise;

it can simply scale as the business evolves and changes.

8) Simple Management: Junos Space Network Director works

across both wired and wireless networks to provide single-

pane-of-glass management of the entire system. This

breakthrough product delivers full life cycle management to

network administrators, providing them with the ability to

see and manage wireless access points and controllers along

with the wired switches comprising their enterprise network,

all from the same application. Furthermore, on the wired

networks, enterprises can perform zero touch provisioning

and automate change management to eliminate errors and

reduce costs.

9) Security: Juniper Networks is the only vendor to seamlessly

enable policy orchestration between WLAN, VPN, network

access control (NAC), and firewall across wired and wireless

networks for a completely unified security policy. Juniper

utilizes the strength of the Interface to Metadata Access

Point (IF-MAP) protocol and ecosystem to coordinate

policy and elevate policy management to a whole new level.

And with Media Access Control Security (MACSec), wired

connections between buildings can be secured against

passive wiretapping, masquerading, and playback attacks

launched from behind firewalls.

10) Unified communications and collaboration applications:

As more enterprises adopt unified communications and

collaboration (UC&C) applications such as Microsoft Lync,

they require high-performance, always-on networks that

can support a large number of wireless client endpoints on

a variety of mobile devices. Juniper’s switches are designed

to prioritize traffic from communications/collaboration

applications such as Microsoft Lync, improving performance

and reliability to deliver a better user experience. On the

wireless side, Juniper’s enterprise access products boast

an advanced data path architecture that reduces network

latency and jitter by minimizing the number of hops that traffic

of service (QoS) capability also allows systems to prioritize

specific types of traffic, such as video or voice. Indeed, Juniper

has achieved such a high standard of performance for UC&C

applications that Microsoft has awarded Lync enterprise

certification to Juniper for both wired and wireless solutions,

giving enterprises the confidence to deploy Lync on their

Juniper network infrastructures.
