In the grand scheme of things, the true value of software defined networking lies not in what it is, but what it does.
Articles by Arthur Cole
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?
What are the capital and operational benefits of software defined networking, and how is the enterprise to know if it's getting its money's worth?
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?
Software defined networking puts the spotlight on the controller—but does it have to?
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.
Old network architectures are fading away. Thanks to SDN, NSX, fabrics and the like, the new network will be an entirely different animal.
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 networking's benefits are clear, but that may not be enough to justify a full rip and replace of all network devices. What else can organizations do?
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.
Art Cole explores hardware and software solutions aimed at optimizing energy consumption and improving the energy efficiency of your network and data center.
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.
