As enterprise computing has evolved, businesses have been shifting to a “hybrid enterprise” where core applications and data can be located in private data centers and public clouds. The growth of hybrid cloud deployments accelerated the transition to hybrid wide-area networks (WANs). Private networks, such as MPLS, are being joined by Internet connections that offer a choice in delivery
channels—costly, but predictable, networks for mission-critical loads and cheaper public networks for bulk loads such as data backups.
Departments of roads and highways around the world have begun to implement technology solutions to improve the safety of their highways, lessen congestion and manage traffic more efficiently. Intelligent Transport Systems (ITS), as these systems are known, require reliable, secure and scalable networks to link cameras, sensors, signage, signaling and vehicles to remote data centers and operation centers.
These networks will be deployed in harsh environments and will pose their own unique challenges to operate, maintain and manage.
In this application note, we will present the unique requirements of ITS networks and discuss how AlcatelLucent Enterprise products and technologies not only meet today’s ITS requirements, but are designed to grow and scale to meet tomorrow’s as well.
Getting your applications to work properly over a Wide Area Network (WAN) is a complex task, and it is not likely to get easier any time soon. Trends such as data center consolidation, the advent of Web 2.0 applications, and the move to web-based application delivery have only served to increase complexity and slow user response times. Often, the result is sluggish application response and at worst, abandoned applications and shopping carts due to slow or failed web page loads. The good news is that you can do something to improve application performance over slow or congested WAN networks. An Application Delivery Network can accelerate your applications and help make sure they’re secure, fast, and available.
To accommodate increasingly dense technology environments, increasingly critical business applications, and increasingly stringent service level demands, data centers are typically engineered to deliver the highest-affordable availability levels facility-wide. Within this monolithic design approach, the same levels of mechanical, electrical, and IT infrastructure are installed to support systems and applications regardless of their criticality or business risk if unplanned downtime occurs. Typically, high redundancy designs are deployed in order to provide for all eventualities. The result, in many instances, is to unnecessarily drive up both upfront construction or retro-fitting costs and ongoing operating expenses.
This paper examines both the centralized WLAN switch architecture and the optimized WLAN architecture, so that the wireless network choice an organization makes today will protect its investment and allow it to experience the substantial benefits of 802.11 for years to come.
Today’s enterprises face new requirements for their datacenter
and cloud architectures, from keeping pace cost-effectively with
fast-growing traffic to ensuring optimal application
performance no matter how quickly business needs or the
enterprise environment evolve. At the same time, IT must reduce
costs and datacenter sprawl, ensure security and uptime, and
prepare for a new generation of cloud computing initiatives.
While many Application Delivery Controller (ADC) solutions
promise to meet demanding customer needs, the reality often
falls short. Taking a closer look at the available options and how
they measure up against the criteria that matter most, it
becomes clear that NetScaler beats the competition—providing
better performance and scalability than F5 Networks, Inc.
Citrix NetScaler is helping prepare enterprises for today’s network challenges while supporting modern virtual, cloud, mobile, social and big data environments. For more information on ADCs, and the cutting edge benefits of NetScaler, read the Network World QuickPulse report, "Take a Load Off Your Data Center"
To try and understand the path to the cloud in greater detail, we’ve
created this eBook from an extended interview conducted by the
team at DatacenterDynamics with Juniper Networks’ Andy Ingram,
the Global Vice President for Data Center and Cloud.
Modern data centers based on hyperscale, leaf-spine switching
architectures are growing so large and complex they are outstripping the
capacity of operators to engineer, configure and manage these networks
using traditional tools and techniques. As a result, data center operators
are looking for new ways to automate workflows, maximize uptime and
increase operational agility while reducing operating costs
With server virtualization now well established in the world's datacenters, IT leaders are turning their attention to virtualizing and centralizing desktop PCs to address some of their toughest computing challenges:
. Managing complex end-user hardware and software infrastructure
. Securing networks and information assets
. Supporting a global workforce in an environment of constant change
The arrival of virtualization, cloud computing, and mobility has strained data center networks—and IT staff—like never before. This Market Spotlight explains how data center network fabrics provide a foundation for automated provisioning, configuration, and management of network-based services in a new era of IT agility.
What is the key benefit of SD-WAN?
To provide seamless access to digital services for end-users.
But IT is more distributed, fragmentary, and dynamic than ever, with hybrid apps, hybrid networks, and remote and mobile users everywhere.
Hardware-bound legacy networks can never fulfill the promise of seamless access. Taming the chaos of today’s IT requires a new approach to networking.
This is the promise of software-defined wide area networks (SD-WAN)—the ability to use plain-language business policies to automate and orchestrate all the components of digital access.
Read this white paper to learn how SD-WAN lets you:
• Manage centrally from a cloud console with a comprehensive view of your connectivity fabric that spans and unifies datacenter/cloud apps, branch/mobile users, and enterprise/cloud networks.
• Orchestrate globally using business policy-based automation to define quality of service and access privileges for all apps/users.
• Deploy locally with zero touch via automated

The businesses that thrive amid fluctuating technology demands are
not only keeping a finger on the pulse of current trends, they have
the infrastructure in place to handle whatever changes might come.
And they’re doing so by treating their data centers as a strategic
asset—a hub from which providers and performance can all stem.
Are you ready for what’s next? According to analyst forecasts and
IT executives, the five key trends affecting our state of technology
are mobility, consumer technology, cloud services, hyperdigitization
and globalization. In the following pages, you’ll learn how these
trends are affecting current networks, and why a strategic data
center is key to not only surviving, but thriving, today and in the future.

A leading U.S.-based financial services firm was faced with the growing challenge of providing consistent application performance to a vast employee base and nationwide network of partners. The company turned to Equinix to help redesign its network, both to
improve performance and prepare for a move to a cloud-enabled environment. Equinix worked with the firm to deploy bi-coastal Equinix Performance Hubs, extension nodes of the company’s existing network placed in strategically located Equinix International Business Exchange (IBX) data centers. A Performance Hub moves services closer to end users and provides direct access to networks and cloud providers. By deploying
Performance Hubs, the customer created a high-performance services platform for its business. The result was a dramatic decrease in network latency, improvements in application performance and an enhanced user experience.
