An SDN for Every Market

Handicapping the growth of the SDN market is a tricky game. But whether you are SME, SoHo, or hyperscale, there is a software defined network out there for you.

Looking Past SDN to the Cloud

Technologies like the software defined network evolve within the confines of wide industry trends. These days, that would be the cloud.

Visibility and SDN: You Can't Manage What You Can't See

SDN's flexible, dynamic nature creates new network monitoring and visibility problems. Here's what networking vendors are doing to solve those problems.

Hardware Customization in a Software-Driven Universe

Programmability will bring unprecedented flexibility to the software defined network, but what about customizing the underlying hardware?

Networking in a Changing Data Environment

Just as networks take their first steps into virtual infrastructure, the data environment and its requirements are changing again.

Networking, Private Cloud, and the Heterogeneous Environment

Some networking vendors aim to unify multi-vendor, legacy data center silos into the interoperable environments private cloud requires.

SDN Makes VDI a TCO Game-Changer

Network virtualization and SDN are finally making VDI viable for the enterprise. Art Cole discusses where it will work best.

Working Toward the Wide Area LAN

Increasing reliance on the cloud is making the WAN critical to enterprise connectivity. Vendors are stepping up to deliver LAN-like functionality for the WANs of the future.

First SDN, Then the Intelligent Network

What are the practical benefits of intelligent networks, and how does network intelligence differ from SDN?

What's Holding Data Center Performance Back?

Data center spending often focuses on performance improvements. But what are the real culprits behind poor performance, and how can you fix it?

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.
