VMware: We're building one of the biggest SDN deployments in the industry

IDGNS staff — Tue, 11 Jun 2013 20:32:08 +0000

VMware hopes to make the networking components of its soon-to-be-released vCloud Hybrid Service one of its biggest selling points, and in doing so the company plans to build one the largest software-defined networking (SDN) deployments in the industry.

Big Switch lowers forecast for OpenDaylight SDN effort

IDGNS staff — Wed, 05 Jun 2013 15:33:13 +0000

Citing concerns over technical and market direction, Big Switch Networks has downgraded its participation in the OpenDaylight consortium, a multivendor effort to define an open source SDN framework.

SDN coming ... soon

Juniper Networks this week will extend its SDN offerings with the release of its controller, roughly six months ahead of schedule.

The cloud's the limit for new Arista, Brocade and HP switches

IDGNS staff — Mon, 06 May 2013 16:06:22 +0000

Cloud scaling will be all the switching rage at this week’s Interop. Three major vendors last week took their platforms deeper into and then beyond the data center, outdueling each other on server access density and software programmability, two key attributes needed for the virtualized goldmine called the cloud. And in so doing, they have raised the bar and perhaps set the stage for one of the more anticipated announcements in SDN switching from Cisco spin-in Insieme.

Clarifying the role of software-defined networking northbound APIs

IDGNS staff — Mon, 06 May 2013 14:57:42 +0000

With software-defined networking the control of the network is pried out of the data handling devices and centralized on a controller that uses a common protocol, OpenFlow, to direct the switches on the southbound side. That much has been established. But what of the oft-mentioned northbound APIs that will let applications tell the controller what they need from the network? What kind of progress is the Open Networking Foundation making on that front?

Arista heading off Cisco/Insieme at 100G SDNs?

HP this week refreshed its switch line and fortified its SDN portfolio with three new systems and a router, along with management and provisioning software extensions.

Here's why you really need SDN

Claims that software-defined networking can't scale in performance divert attention from SDN's huge benefit: flexibility.

IBM defends OpenDaylight from doubters

IBM is asking that people judge the OpenDaylight SDN project by its accomplishments, not by its roster.

Open Networking Foundation director details SDN directions, OpenDaylight impact

IDGNS staff — Thu, 18 Apr 2013 18:39:38 +0000

The third annual Open Networking Summit, an SDN conference organized by the Open Networking Foundation, convened this week just after ONF members Cisco and IBM unveiled a separate effort to define an open source SDN framework. Unlike the user-driven ONF, OpenDaylight is a vendor-driven project to cultivate a system of SDN applications, but it also raised suspicion of the group's real intent: Is it designed to stall SDN's momentum and the threat, real or perceived, it could pose to incumbent hardware vendors? ONF Executive Director Dan Pitt discussed some of these topics with Network World Managing Editor Jim Duffy at the Santa Clara, Calif., conference.

Intel lays foundations for SDN gear that could shake up networking
