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

The enterprise isn't yet equipped to deal with the consequences of SDN, because no one knows what those consequences will be.
Advanced cloud architectures will require advanced network infrastructure in the data center.
The road to 100 Gbps+ Ethernet is proving more complicated than it first appeared, at least for those considering hyperscale deployments.
Network fabrics imply a flattened architecture that eschews centralized switching. So why are vendors still talking about core fabric switches?
Hyperscale implies massive infrastructure, but key technologies may wind up in standard enterprise settings as well.
Even with the advent of highly fluid virtualized data environments and SDN, choices like open vs. proprietary remain.
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—or perhaps Nvidia's PCIe alternative—holds the potential to transform data infrastructure on a micro level.
Enterprise interest in commodity hardware for SDN threatens the dominance of proprietary hardware vendors like Cisco. How does ACI address the problem?
Converged infrastructure is great for plug-and-play provisioning, but first you have to decide what kind of network you want.
To build a multi-site data ecosystem, the enterprise needs to push SDN past the edge. The software defined WAN is coming.
Far from a simple networking play, SDN is poised to rewrite the entire data infrastructure paradigm.
No matter how they're defined, all networks share the need for greater bandwidth to deal with increasing traffic.
To bring shadow IT under control, IT departments must accept its inevitability and find ways to manage its use.
Application awareness may sound like just a buzzword, but its practical benefits may soon be necessary to the enterprise network.
Beyond SDN lies AAN and the path to a truly optimized application environment.
Data center virtualization and the next wave of the cloud will demand what software defined networking has to offer.
Cisco makes the jump into services, but can it make the switch from dominant player to hungry newcomer?
Building an entire new SDN-optimized infrastructure is a daunting task. Perhaps the overlay approach on legacy networks isn't so bad.
All the activity coming from abstract resources can overwhelm anything still operating on the physical plane, including storage.
Stepping outside the SDN bubble, is the noise around SDN real?
In the grand scheme of things, the true value of software defined networking lies not in what it is, but what it does.
SDN can take you where no network has gone before, but you may have to rethink the forwarding table.
Despite widespread recognition that wide area networks will play a vital role in the move to distributed architectures, few enterprises seem willing to shore up their own infrastructure.
Open source and open standards are becoming increasingly important in the SDN sphere, but openness isn't a magic bullet.
Many enterprises are bent on deploying hybrid clouds in the coming year, but how should they be networked?
Hyperscale data environments are coming. Contributions to Facebook's Open Compute Project reveal surprising strategies for maximizing them.
SDN vendors and early adopters are dreaming big. But will their dreams become reality, or will the results prove to be less than they'd hoped for?
The acquisition of Corente will bring Oracle new WAN virtualization and wide area SDN capabilities. What's Oracle's end game?
Software defined networking puts the spotlight on the controller—but does it have to?
The U.S. Court of Appeals this week struck down the FCC Network Neutrality order. What does this mean for the Internet as we know it?
Network hardware, even the lowly router, will have to change its behavior if it is to adequately support the virtual data center.
Software defined networking over the WAN will someday be a necessity. What challenges must vendors solve to make it a reality?
Before software defined networking can achieve its lofty goals, the orchestration pieces need to fall into place.
Now that the enterprise has entered the SDN deployment phase, its time to start thinking about what you'll actually do with it.
SDN, network fabrics and increased intelligence will help with crushing data loads, but so will plain, old raw bandwidth.
Even SDN won't provide everything that wide area data environments require. How can enterprises optimize their distributed infrastructures?
Truly open networking is a nice dream, but is it really what the enterprise needs? Open source and open standards create challenges of their own.
Software defined networks and the distributed data center will require intelligence, interoperability, and agility at the network edge.
Enterprises just finishing up the conversion to 10 GbE still have a fair amount of work to do to achieve a truly dynamic data center.
SDN announcements from networking vendors like Cisco, Arista, Juniper, and Brocade mark the next step in the software defined revolution.
SDN may one day change everything you know about the network. Fear of this change will hold you back, but perhaps some caution is warranted.
Even private clouds often rely on public infrastructure. How can Ethernet address the resulting concerns, and which vendors are on top of the issue?
The fully software defined data center looks closer than ever, but before it can be realized, the software defined movement must address the storage question.
Software Defined Networking is the Next Big Thing, according to its proponents. But is it really, and does everyone truly need it?
Virtualization, cloud, and SDN demand optimal WAN performance. Check out some vendors promising to provide just that.
Technology serves as a means to a business end. In the case of SDN, the end is the on-demand data center. What does that mean, and how are vendors working to get there?
New network processing technology looks set to speed us into the SDN, mobility, Internet of Everything future.
As data environments change, so too must the data center itself. That includes its network infrastructure.
