SDN: It’s All About the Apps

SDN application development efforts look set to increase the capabilities and value of software defined networks in the enterprise.

SDN: A Study in Action and Reaction

The enterprise isn't yet equipped to deal with the consequences of SDN, because no one knows what those consequences will be.

The Road to the Cloud Runs Through the Network

Advanced cloud architectures will require advanced network infrastructure in the data center.

Ethernet Faces High-Bandwidth Growing Pains

The road to 100 Gbps+ Ethernet is proving more complicated than it first appeared, at least for those considering hyperscale deployments.

SDN Automation: Not as Simple as You Might Think

Automation and SDN seem to go hand in hand, but several challenges still need to be solved before automation is automatic in software defined networks.

Should the Fabric Have a Core? Perhaps for a Little Longer

Network fabrics imply a flattened architecture that eschews centralized switching. So why are vendors still talking about core fabric switches?

Hyperscale Networking: Coming to a Data Center Near You?

Hyperscale implies massive infrastructure, but key technologies may wind up in standard enterprise settings as well.

Open vs. Proprietary SDN: New Technologies, Same Old Dilemmas

Even with the advent of highly fluid virtualized data environments and SDN, choices like open vs. proprietary remain.

SDN Still Has to Prove Itself to the Enterprise

SDN must overcome several key challenges before it can make it through the hype cycle and establish itself on the other side.

PCIe 4.0 and the Data Center

PCIe 4.0—or perhaps Nvidia's PCIe alternative—holds the potential to transform data infrastructure on a micro level.

Cisco, ACI, SDN, and the Commodity Networking Challenge

Enterprise interest in commodity hardware for SDN threatens the dominance of proprietary hardware vendors like Cisco. How does ACI address the problem?

Network Infrastructure Concerns for Big Data

Big Data initiatives require a rethinking of current data center network infrastructure. Is your network ready to enable business analytics on a large scale?

Networking for Converged Infrastructure

Converged infrastructure is great for plug-and-play provisioning, but first you have to decide what kind of network you want.

The Dynamic Cloud Needs the Software Defined WAN

To build a multi-site data ecosystem, the enterprise needs to push SDN past the edge. The software defined WAN is coming.

The Big Picture: SDN and the Dynamic Data Environment

Far from a simple networking play, SDN is poised to rewrite the entire data infrastructure paradigm.

Big Volumes Call for Big Networking

No matter how they're defined, all networks share the need for greater bandwidth to deal with increasing traffic.

Shining a Light on Shadow IT

To bring shadow IT under control, IT departments must accept its inevitability and find ways to manage its use.

Application Aware Networking and the Enterprise

Application awareness may sound like just a buzzword, but its practical benefits may soon be necessary to the enterprise network.

From Software Defined to Application Aware Networking

Beyond SDN lies AAN and the path to a truly optimized application environment.

SDN: The Key to Computing in the Cloud

Data center virtualization and the next wave of the cloud will demand what software defined networking has to offer.

The Global Intercloud: A Whole New Ball Game for Cisco

Cisco makes the jump into services, but can it make the switch from dominant player to hungry newcomer?

Overlay Networks: Is SDN-Lite Good Enough for Now?

Building an entire new SDN-optimized infrastructure is a daunting task. Perhaps the overlay approach on legacy networks isn't so bad.

Your Network May Be Ready for SDN, But What About Your Storage?

All the activity coming from abstract resources can overwhelm anything still operating on the physical plane, including storage.

SDN in the Enterprise: It’s the Applications, Stupid

In the grand scheme of things, the true value of software defined networking lies not in what it is, but what it does.

Scaling the Virtual Network

SDN can take you where no network has gone before, but you may have to rethink the forwarding table.
