The Dos and Don’ts of VPNs
The twin forces of greater data mobility and the need to maintain high levels of security and protection are leading many organizations to embrace virtual private networks (VPNs). The technology is not new, of course, but it is becoming commonplace both as an...
The Rise of Programmable Network Hardware
One of the more ironic aspects of modern network infrastructure is that while high levels of customization are taking root on virtual architectures, the physical layer is becoming increasingly generic. But even that may be about to change now that the ability...
How AI Will Change Network Infrastructure
Much has been said about the way artificial intelligence (AI) will alter the networking landscape, usually in reference to its ability to enhance traffic management, analytics and the provisioning of virtual resources. But AI will also have a pronounced...
Network Automation: From Dream to Reality
Network automation offers a compelling vision of what data environments could be, but most enterprises are still struggling with the practical issues of implementing the technology on legacy infrastructure. This should come as no surprise, considering the...
P4: The Language of SDN
Software defined networking (SDN) puts a new spin on network provisioning and management. Going forward, new architectures will be programmed to function in all sorts of novel ways, so it stands to reason that the programming language chosen for this task...
Hyperscale Networking Requires More than Just Bandwidth
The data center is being pulled in two different directions as the enterprise strives for the perfect balance between hardware consumption and expanding data loads. On the one hand, on-premises infrastructure is getting smaller and more modular, while on the...
Hyperscalers Confront Their Networking Challenges
Hyperscale cloud centers are named so for a reason. They’re big. Really big. At the same time, they also incorporate highly dense modular infrastructure, which means they pack a lot of data points, both physical and virtual, in confined areas. All of...
Why VPNs Are Better with SDN
Software defined networking (SDN) brings many benefits to the enterprise – streamlined architecture, network agility, even improved security. But on a fundamental operations level, its chief advantage is that it allows users to establish virtual private...
MEC: The Glue That Will Hold the IoT Together
The IoT is driving demand for new forms of network connectivity on the edge, which naturally spurs the need for new standards. It appears that one of the more crucial aspects of this new edge architecture is already making its way into commercial releases,...
Relax, Programming Is Not Required for SDN
One of the more unsettling aspects of software-defined networking (SDN), at least from the network manager’s perspective, is the idea that before long the enterprise network won’t be managed as much as programmed. This has led to some justifiable...
