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.

IDC: SDN is a Buzzword

Stepping outside the SDN bubble, is the noise around SDN real?

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.

Cloud, Mobile, M2M: They All Rely on the WAN

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.

OpenDaylight, Hydrogen, and the Vagaries of Open Networking

Open source and open standards are becoming increasingly important in the SDN sphere, but openness isn't a magic bullet.

The acquisition of Corente will bring Oracle new WAN virtualization and wide area SDN capabilities. What's Oracle's end game?

SDN: New Opportunities and Challenges for the Network Controller

Software defined networking puts the spotlight on the controller—but does it have to?

The Network Neutrality Ruling and Network Admin: Are You Worried?

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?

Will SDN Lead to a New Type of Router?

Network hardware, even the lowly router, will have to change its behavior if it is to adequately support the virtual data center.

Wide Area SDN: Close, But…

Software defined networking over the WAN will someday be a necessity. What challenges must vendors solve to make it a reality?

Now that the enterprise has entered the SDN deployment phase, its time to start thinking about what you'll actually do with it.

Flexibility Rules, But Don't Neglect Network Capacity

SDN, network fabrics and increased intelligence will help with crushing data loads, but so will plain, old raw bandwidth.

Networking Challenges to the Distributed Enterprise

Even SDN won't provide everything that wide area data environments require. How can enterprises optimize their distributed infrastructures?

Open SDN is Not Worry-Free SDN

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.
