What issues could containers cause in a virtualized network, and what are vendors doing to address them?
As enterprises take their first steps towards SDN, how should they manage the transition for best results?
What will be the killer app for SDN, and does there have to be only one?
The student becomes the master as OpenFlow visionaries re-unite at VMware.
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.
Technologies like the software defined network evolve within the confines of wide industry trends. These days, that would be the cloud.
SDN's flexible, dynamic nature creates new network monitoring and visibility problems. Here's what networking vendors are doing to solve those problems.
Programmability will bring unprecedented flexibility to the software defined network, but what about customizing the underlying hardware?
Just as networks take their first steps into virtual infrastructure, the data environment and its requirements are changing again.
Some networking vendors aim to unify multi-vendor, legacy data center silos into the interoperable environments private cloud requires.
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.
What are the practical benefits of intelligent networks, and how does network intelligence differ from SDN?
Data center spending often focuses on performance improvements. But what are the real culprits behind poor performance, and how can you fix it?
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.
