April 08, 2013OpenFlow can be introduced into production networks in several ways. I’ll look at two options for deploying OpenFlow that network engineers can use to test the protocol and get their feet wet with SDN.
April 02, 2013A new SDN competitor is challenging VMware, Cisco and others. Nuage Networks, an Alcatel-Lucent venture, has announced Virtualized Service Platform (VSP), an SDN technology that employs virtual switches and network overlays.
March 26, 2013APIs are helping to usher in new mechanisms for making data center management more automated and scalable. They’re also key to network virtualization and private clouds.
March 15, 2013NSX, VMware's data center network virtualization platform, is really about public and hybrid clouds, where VMware has plans for growth. Here's why.
March 13, 2013VMware announces NSX, a software platform that combines its vCloud Network and Security software with Nicira's NVP. The combined platform provides network virtualization via vswitches and a centralized controller.

Software-defined networking is in an enviable position: Everyone is excited about the concept and wants to believe in it. Among networking professionals, expectations are high. But don't make the mistake of looking at SDN as just a new tool to solve yesterday's problems.
are falling into this trap as they seek to market and monetize SDN before the new-car smell wears off. OpenFlow, because it's a standard, is an exception, but we see SDN-like capabilities baked into a number of proprietary and only partially standards-based systems. Sure, most vendors promise to support OpenFlow in addition to proprietary code, but the temptation is strong to "embrace and extend."
As chief architect of the InteropNet and CEO of a technical design company, I understand that it's normal for IT organizations to come at software-defined networking from the perspective of an engineer: What's broken that can be fixed by the ability to program a network to dynamically change its operating mode or parameters via a programmatic method?
Use SDN to make the current network better, sure. But it's more important to think differently about how SDN will help us design and build the network of the future.
February 26, 2013Layer 2 multipathing standards such as TRILL and SPB may seem redundant in an SDN world. But these standards still have a role to play while we wait to see how the SDN market matures.
February 15, 2013SDN startup Anuta Networks is launching a controller for IaaS cloud providers to manage physical network infrastructure—switches, routers, load balancers and more—and to automate the provisioning of network services.
February 12, 2013News roundup: F5's LineRate Systems acquisition targets data center programmability, scalability; Dell launches a new switch and rolls out OpenFlow support; CA simplifies IAM offerings; Veeam offers VM backup up to 15 cloud providers.
February 04, 2013Cisco's SDN architecture gets its keystone with the launch of the Cisco ONE Controller, a software package that supports OpenFlow and its own onePK APIs. Cisco also announced support for hybrid clouds with its Nexus 1000V product and the Nexus 6000, a new data center switch.

VXLAN is an Experimental IETF draft of protocols to enable the creation of a large overlay, multi-tenant network.
: OpenFlow is poised to reach over-hyped status, yet there are practical, useful reasons for keeping an eye on Openflow. The biggest cloud players are involved and driving the feature creation.
