Software Defined Networking

American comedian Louis C.K. once observed on Late Night with Conan O’Brien that ”everything is amazing and nobody is happy.” And you know what? He’s right. He riffs about people complaining about the uncomfortable seats on a plane – despite the fact that they are partaking in the mi...
“Software-defined,” like any new trend that technology companies rush to attach to has suffered from marketing hype. Starting in mid-2012 with the acquisition of Nicera by VMware, most traditional infrastructure technology vendors across compute, networking, and storage have some messa...
Today’s software-defined networking (SDN) and virtualized networking solutions focus on virtualizing network functionality within the data center and the metropolitan area network (MAN). But for typical enterprises, and those managed and cloud service providers that cater to them, thes...
In my last blog, I looked at the ways in which Software-Defined Network (SDN) and Network Functions Virtualization (NFV) enhance flexibility and allow for greater services mashups, and I ended with the question of how billing and compensation will support these new capabilities. With ...
In my previous blog, I suggested that both Software-Defined Networks (SDN) and Network Function Virtualization (NFV), although arguably different in intent and in detail, are nevertheless both driving the evolution of network architecture in the same direction. Network functions are ab...
In a previous blog I took the opportunity to comment on the role of billing in a future of Software Driven Networks (SDN). However, before we get too caught up in the billing component, it might be worthwhile to discuss where SDN itself is going and to tease out some of the distinction...
Announcements over the past several months including VMware's NSX, HP's SDN SDK, and others show that Software Defined Networking (SDN) is hitting the mainstream in a large way. Conventional wisdom is that SDN is still early in the "hype cycle", but a closer looks reveals that SDN may...
In just a few short recent years the idea of software-defined networks (SDN) has moved from a theoretical academic concept to a real-life practical proposition for making the world’s telecommunications networks more efficient, cost-effective, easier to manage and resilient. The SDN con...
The enterprise is increasingly resorting to cloud services for many applications ranging from efficient application hosting or low-cost backup and archiving to cloud data centers. Typically, enterprise networks are interconnected to the cloud over low speed IP networks that are limited...
SDN is a new, dynamic network architecture that transforms traditional network backbones into more intelligent service-delivery platforms. IT leaders can use SDN as a tool to change the way they do business. For example, enterprises can foster closer relationships with their customers ...
Software-defined networks are all the rage these days – and why not? They offer the promised benefit of making networks far more agile and responsive to dynamically changing application requirements. Consequently, in theory, the entire networking-computing-storage-applications ecosyste...
As the cloud market explodes, a distinct chasm has become apparent between the operation of infrastructure and applications. Sharing, isolation and load balancing issues in the network, combined with high density virtualization in compute and storage resources, can adversely impact the...
Software Defined Networking (SDN) has become a famous paradigm and also the bandwagon in the networking industry today. SDN is primarily considered to be a methodology or approach to solving some of the wider-known problems in the enterprise and service provider networking space. It’s ...
As the proliferation of data continues, traditional networking infrastructure is struggling to keep up with the world’s influx of information and data. Legacy networking technologies are in need of an overhaul and software-defined networking (SDN) has been touted as the response and th...
More and more of our lives are lived online. Our music collections, bookshelves, vacation memories and more are increasingly digitized and uploaded into the cloud, the vast network of server farms that provide the bulk of online storage today. Research firm Gartner projects that by 201...
Using OpenFlow to extend software-defined networking (SDN) to the optical layer is a compelling prospect for enterprises seeking to achieve joint orchestration of information technology (IT) and network resources for cloud services, to virtualize the network and to more simply manage i...
SYS-CON Events announced today that the 1st International Software Defined Networking Conference will take place June 10-13, 2013, at the Javits Center in New York City. Software Defined Networking Conference is co-located with 12th Cloud Expo and 3rd Big Data Expo. According to a rec...
There’s a new wannabe disruptive initiative abroad in networking land that’s promising to run roughshod over laggards and standoffish old stalwarts like Cisco that may find it threatening. The push is gathering behind a deceptively named two-year-old start-up called Big Switch Ne...
“Cloud service providers are drawn to Software Defined Networking for its technological, operational, and business benefits,” said Brad Casemore, Research Director, Data Center Networks at IDC, as Pica8 Inc. recently announced the industry’s first open SDN reference architecture. “I...
SYS-CON Media has launched SDN Journal on Ulitzer.com featuring over 300 original articles, news stories, features, and blog entries. Software-defined networking (SDN) is an approach to networking in which control is decoupled from hardware and given to a software application called a ...
