SD-WAN providers are building products that are replacing routers in the branch office. Gartner says half of WAN edge infrastructure refreshes will be based on SD-WAN by 2020.
WAN Get Started
Bring yourself up to speed with our introductory content
The SD-WAN market beckons with high-growth potential, but channel partners must confront incomplete feature sets, training requirements and market consolidation. Continue Reading
Should IoT deployments use LPWAN technologies, 3GPP technologies or both? Consider the benefits and use cases -- and the flaw that needs remediating. Continue Reading
Synchronous replication copies data over a SAN, LAN or WAN so multiple copies are available. The technique is used for applications with low recovery time objectives. Continue Reading
Evaluate WAN Vendors & Products
Weigh the pros and cons of technologies, products and projects you are considering.
The list of SD-WAN benefits often includes cost savings and better routing; does it also include better quality of experience compared to a traditional WAN? Continue Reading
A growing number of network managers have their heads in the cloud, and that's a good thing. Cloud-based networking technologies are emerging to help solve a number of enterprise problems, and organizations are busy exploring what "the networked cloud" will mean for them. While some network pros are dipping cautious toes into the cloud-based networking waters with individual, subscription-based services that integrate with their existing infrastructure, others are rolling out technology that lets them manage the migration of their applications to the cloud with a high degree of visibility and control. This edition of Network Evolution examines how cloud-based networking can make network managers' lives easier in a new era of IT.
Also in this issue, find out whatever happened to the legacy voice engineers of yore, since voice over IP technology threatened to render their traditional circuit switching skills more or less obsolete in the 1990s. We catch up with a few such professionals who -- far from phoning it in -- learned new skills that took their careers in unexpected directions.
And last but not least, we explore Microsoft's upcoming Azure Stack release -- and whether it could become a major player in the software-defined networking space.Continue Reading
When looking for the right SD-WAN architecture to implement, it's important to consider your specific network and the traffic it experiences. Continue Reading
Learn to apply best practices and optimize your operations.
The best answer for creating virtual service management may be a hybrid approach that combines end-to-end analytics-based and service-level management. Continue Reading
If you think enterprise WAN is "been there, done that," think again. The mobile workforce is redefining the role of the wide area network and the nature of the WAN connection. New technologies related to link aggregation and software-defined provisioning are bringing new capabilities to an old standby.
WAN connection types have evolved from T-1s and Integrated Services Digital Network links to dynamic pipes capable of supporting bandwidth-intensive applications. What's next? Things like the software-defined WAN, or SD-WAN, which has significant implications for many aspects of your WAN, including application delivery. WAN connections in the cloud, too, are at the forefront: You can extend your private WAN to the edge of the cloud service provider's network via WAN Cloud eXchange.
This technical guide discusses the evolution of the WAN and give you an idea of the new tools that will make your office connectivity infrastructure more robust.Continue Reading
There are many SD-WAN benefits for the enterprise, including cost savings, better app delivery and more. Learn how to software define your wide area network. Continue Reading
Problem Solve WAN Issues
We’ve gathered up expert advice and tips from professionals like you so that the answers you need are always available.
A simple congestive overload of a low-speed link was the problem, but diagnosing the network speed check wasn't simple -- or easy. Continue Reading
The data center interconnect market is poised for significant growth, thanks to a number of factors altering the IT landscape -- including the growing use of cloud services, the massive proliferation of data, the increasing adoption of hyper-converged data center designs and the evolution of network traffic behavior. In fact, some analysts at Ovum Research predict data center interconnect market revenue will experience a compound annual growth rate of 10.5% over the next few years, reaching $4.2 billion by 2019.
As long as information generation continues to increase -- a virtual inevitability -- organizations of all shapes and sizes will find themselves in need of faster, more reliable, higher-capacity connections. In this edition of Network Evolution, we examine how demand from both service providers and enterprises for speedy, scalable interconnect links are driving upgrades -- whether from 1 Gbps to 10 Gbps, or from 10 Gbps to 100 Gbps -- and moving the data center interconnect market forward.
Also in this issue, we explore Cisco's recent updates to the Cisco Certified Internetwork Expert (CCIE) written exam, and consider whether those changes will help keep the certification relevant in the era of cloud, the internet of things and programmable networks. IT pros on both sides of the CCIE fence weigh in on the ongoing debate. We also head back to the classroom to find out how American universities are tackling the question of software-defined networking education, and what that means for the network managers of tomorrow.Continue Reading
Under some circumstances a WUDO backfire on narrow WAN pipes can occur when sending or receiving updates to/from other PCs on the Internet. Continue Reading
