Cisco's ONE Controller Debuts; Targets SDN
February 04, 2013
Cisco'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.Indiana University Expands SDN Research Lab
January 25, 2013
Indiana University's network research unit, the Indiana Center for Network Translational Research (InCNTRE), is now serving as a test bed for OpenFlow and other software-defined networking (SDN) products. On Wednesday, it hosted the kickoff meeting of a new business user group devoted to software-defined networking.
The InCNTRE Software-Defined Networking User Group (ISUG) brought together network administrators from Fortune 500 companies in finance, insurance, healthcare and travel, according to Matthew Davy, executive director of InCNTRE.
"Private sector network engineers, network architects and IT managers are busy getting up to speed on software-defined networking and trying to understand how it will affect their networks," said Davy in an announcement of the meeting on the InCNTRE website. "Given our expertise, it made perfect sense to form the ISUG as a way to facilitate the flow of information between IU's SDN experts and the private sector," he said.
The OpenFlow protocol separates the control plane from the forwarding plane in switches, so that software applications on a central controller can issue instructions to switches and routers to change the nature of the network.
New OpenFlow Controller, Virtual Switch Debut from NEC
January 22, 2013
As SDN technology evolves, NEC has launched a new version of its OpenFlow controller that supports IPv6 and OpenStack. NEC has also released a virtual switch to support OpenFlow in Hyper-V environments.Juniper's SDN Strategy Looks Beyond OpenFlow
January 15, 2013
Juniper gets SDN religion, but as the company outlined its tenets, it's clear Juniper doesn't hew to the OpenFlow orthodoxy.Plexxi Cuts a New Path to SDN
December 05, 2012
Plexxi, an SDN startup, launches a custom switch and controller to enable software-defined networking for enterprises and cloud providers. Unlike other controller architectures, Plexxi doesn’t rely on OpenFlow. Its secret weapon? An optical interconnect.Alcatel-Lucent’s SDN Strategy Downplays OpenFlow
November 30, 2012
Alcatel-Lucent has announced its SDN roadmap for the coming year. The company plans to offer a RESTful interface in two of its OmniSwitch product lines before it adds support for OpenFlow.SDN Is Business, OpenFlow Is Technology
November 15, 2012
Software-defined networking (SDN) and OpenFlow aren’t the same thing. We’ll clarify the technical differences and discuss a more important distinction: SDN emphasizes applications that drive network usability and business requirements, while OpenFlow is a technology to link an SDN controller and network devices.Extreme Networks' 40 GbE, 100 GbE Switch Modules Target Data Centers
November 15, 2012
Extreme also opens up its OS to support OpenFlow 1.0 and OpenStack to enable more flexible network architectures.Big Switch's OpenFlow Controller Guns for SDN Leadership
November 13, 2012
Big Switch Networks, an ambitious start up in software-defined networking (SDN), has launched a new controller and a pair of networking applications that have the potential to drive OpenFlow-based networks into the mainstream.VMware Does Complicated Dance With Open Source
November 09, 2012
When it comes to thinking about the future data center, it's well understood that servers and storage will function as pools of virtualized resources that can automatically switch from task to task. Networking is a much harder nut to crack. It remains unvirtualized and has lagged far behind the other two. But without it, we'll never get to the flexible, automated data center of the future envisioned as a "private cloud." That's why I sat down to talk to Martin Casado, the former Stanford grad student whose PhD thesis turned into the OpenFlow networking protocol. Casado co-founded virtual networking firm Nicira, which soon became the lead contributor to OpenStack's virtual networking project, Quantum. VMware bought Nicira for $1.26 billion in July -- not bad for a young company with 100 employees. I'd asked Casado to explain how Nicira was going to continue to lead development of virtual networking in OpenStack, since open source OpenStack competes directly with VMware to manage the virtualized part of the data center that's implementing automated self provisioning, elastic expansion and chargeback -- the private cloud part.
