Frost & Sullivan review the limitations associated with a single-provider approach to MPLS networks and its impact on the enterprise. They examine Virtela's Global Service Fabric - a multi-carrier network approach that provides a best-of-breed global MPLS network solution.
This is a case study which shows how Voorhees College implemented a revolutionary communications solution based around a service-orientated Unified Communications architecture from NEC to provide students, faculty and staff in five locations with software-based voice and desktop communications tools to achieve a 40 percent savings over its previous traditional telephony solution.
The Time for the Hybrid WAN IT has gone through a significant evolution over the past decade. Virtualization has changed the entire face of the data center, the network edge has become predominantly wireless and consumer devices reign supreme. However, one of the few areas of IT that has yet to evolve is the corporate wide area network (WAN). Managing the WAN is something network managers have always struggled with because WAN speeds are typically an order of magnitude, or more, slower than local area networks (LANs).
A discussion of wide area networking is extremely timely because after a long period with little if any fundamental innovation, the WAN is now the focus of considerable innovation. As a result, for the first time in a decade network organizations have an opportunity to make a significant upgrade to their WAN architecture.

This white paper illustrates how the integration of zero touch provisioning with EdgeConnect profiles, and the further integration of local profiles into the global business intent of Silver Peak’s virtual overlays, fulfills the promise of SD-WAN with virtualised wide area networking.
While business application turn-up on virtual compute platforms takes only minutes, the network configurations to connect your employees at the branch to these applications can take weeks or even months to rollout!

Data transfer bottlenecks and unpredictability on the Wide Area Network (WAN) can hurt application performance. In addition, the time required to migrate large volumes of data to and from data centers can be a serious concern to business continuity.
This e-book includes a summary of the key components of some of the emerging approaches to WAN architecture and design and concludes with a call to action that outlines a project plan that network organisations can use to evolve their WAN.
The wide-area network optimization controller market is maturing rapidly, but remains dynamic, with a high level of innovation from vendors. Organizations looking to acquire WOC capabilities should identify their specific needs and conduct real-life trials before committing to any purchase.
Primary internet connections fail for a variety of reasons: severe weather, downed poles and lines or simply heavier than usual network congestion. Business continuity solutions provide businesses with back-up internet access via a cellular network when primary Wide Area Network (WAN) connections fail or are over-loaded. These solutions enable businesses to:
Maintain seamless, uninterrupted access to the internet
Process credit card transactions
Access to important information stored online
This paper will provide an overview of business continuity solutions, examples of in-use scenarios and a path to adoption in an easy to understand and digestible way. Download now.

This paper is intended for people who will be proposing solutions, providing installation services or consulting, and who may be assisting in deploying Office SharePoint Server 2007 solutions accessed over a Wide Area Network (WAN). It will also be of interest to IT professionals who may be deploying and/or managing such Office SharePoint Server 2007 solutions.
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.

Interconnecting three or more sites across a metro or wide area network has traditionally been accomplished via a hub and spoke network topology using Private Lines, Frame Relay or IP VPNs over the Internet. Ethernet services support hub and spoke topologies but also support an “any-to-any” network topology similar to a LAN but delivered over a wide area. This latter capability is unique to Ethernet services and cannot be cost effectively delivered using legacy point-to-point technologies such as Frame Relay or IP VPNs.
This paper discusses two options for multi-site connectivity using Ethernet services. One option discusses the classical hub and spoke topology using Ethernet Virtual Private Lines (EVPL). The other option discusses the “any-to-any” topology using an Ethernet Private LAN (EP-LAN) service. Through examples, the paper illustrates the capabilities of the two approaches and their benefits.
One of the leading ways that today’s organizations are providing secure, reliable and scalable answers for their networking needs is through MPLS IP-VPN network usage. However, businesses are also looking to create Intelligent WAN that integrates security, application performance management, and cloud services in order to create more intelligent wide area networks. This paper examines how to use the attributes of MPLS-based VPNs to enable enterprises to create a truly intelligent WAN, discussing key planning, implementation and management considerations to pave the way for a more intelligent and cloud-enabled WAN.
