VMware has contributed plug-ins to the OpenStack Project that guarantees the project's networking platform will recognize and work with virtual machines running under VMware's vSphere management environment and VMware's Nicira Network Virtualization Platform.
VMware acquired startup Nicira last July for $1.26 billion and has made its NVP the basis of future virtualized networking in what it terms "the software-defined data center." The Network Virtualization Platform from Nicira, a leader in OpenFlow network protocol concepts, is also the basis for the Quantum networking platform in OpenStack. Nicira was a heavy contributor to OpenStack before the acquisition, and it remains one now. At the OpenStack Summit on Tuesday, VMware gave these contributions a particular cast. Through close collaboration between Canonical and VMware, they will work inside the Ubuntu distribution of OpenStack, according to VMware's VP of vSphere product management Joshua Goodman.
Suse Linux and Red Hat also have distributions of OpenStack. Red Hat's KVM hypervisor is the one native to the OpenStack cloud open source code. Suse Linux is often cited as the version that works most closely with Windows Server and its hypervisor, Hyper-V. Both are keen competitors of VMware's ESX Server.
The move also reflects VMware's growing realization that it is likely to need to live with many OpenStack implementations in the future, despite its early hopes that its own cloud software stack, the vCloud Director suite, would be the basis of private and public clouds everywhere. The collaboration with Canonical gives it an OpenStack partner that is less an immediate competitor than either Red Hat or Suse.
April 18, 2013The march to SDN designs has led many to think we're entering an era of dumb switches. Instead, look for the commodity silicon to get a lot smarter.
April 15, 2013InteropNet provides the IT infrastructure for Interop conference attendees and exhibitors. Here are some of the people who make it happen.
April 09, 2013Floodlight is an open source controller for SDN. Here’s how to set it up to use with OpenFlow-enabled switches for testing and development.
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.
