This article is a snapshot of recent news in software-defined networking (SDN) and network functions virtualization (NFV). Topics include the Open Networking Foundation adding a wireless and mobile group, EMC offering a hybrid cloud, Pluribus opens shop in the UK, and talk of the OpenDaylight summit.
The OpenDaylight Project gets its chance to shine this week, as its first code release, named Hydrogen, is due to come out Tuesday, coincident with the start of the first OpenDaylight Summit, which runs Tuesday and Wednesday.
The move towards software-defined networking means that new combatants will be stepping into what has been traditionally a sparsely populated networking boxing ring. It was always only a matter of time before the networking guys stepped into applications, and the application guys stepped into networking.
Its sometimes the less sexy and more subtle happenings at the fringe of media interest that determine how industries will evolve and ultimately who will win and lose. This past year was certainly the year of software-defined networking, but what important supporting bits played out just out of the limelight?
Engineers in switching and software-defined networking (SDN) have been leaving Juniper steadily for the past year, having been deeply alienated by management after the acquisition of Contrail, sources tell SDNCentral.
Oracle announced that it’s buying Corente, a WAN virtualization startup with Bell Labs in its genes and BT Group on its customer list. Terms weren’t disclosed.
Riverbed has attracted the attention of an activist hedge fund that’s offering about $3.08 billion to take the company private.
The notion that the network needs to be more of a willing partner in delivering application experience is not necessarily unique. But solutions to delivering such an infrastructure have hinged primarily on management, ignoring the very static nature of the underlying connectivity the network provides.
While that killer use case for makes software-defined networking (SDN) and network functions virtualization (NFV) remains as elusive as the Alaskan blue crab, three important use cases are making progress into customer networks.
The white box switching movement appears to be gaining some momentum. For some, it is a fait accompli that hardware and software will be meaningfully separated, allowing users to procure each independently in a model that more closely resembles what happens on the server side. The fires are fueled by projects like Facebook’s Open Compute Project.
Looking back at how 2013 was the most amazing year for software-defined networking (SDN) yet, I spent some time browsing the SDN and network functions virtualization (NFV) demos we hosted on SDNCentral during the DemoFriday series this past year.
Since software defined networking is mainly controlled through applications instead of ports, that's where industry-watchers expect network engineers to be doing more of their interaction with the network in the future, not through the command-line interface.
Lori MacVittie sees some software-defined networking models taking an approach similar to IoC and giving control to the applications on the network, but many models of SDN still keep the network in the driver's seat with SDN controllers using an OpenFlow-based model.
Infonetics Research and InformationWeek both released surveys this month about SDN adoption. Seems similar to cloud computing adoption several years ago.
A recent post on Moor Insights & Strategy takes a comprehensive look at the challenges and barriers that software-defined networking will have to pass before it can become a reality at the majority of IT firms. The article has a nice list of some major SDN Vendors and a snapshot of their progress towards removing these barriers.
We hear both that NFV is moving very fast and getting traction, and yet also hear that it’ll take a while to get standards created — for example, what hypervisor standards, what orchestration standards aren’t defined yet. Do you think we’ll see early standards being published?
Compare the differences between the three new major open-source controllers and provide my opinion of how this will play out in 2014. Also see what service providers and enterprises ought to consider as they move ahead with their SDN and NFV strategies.
To understand the value of open-source controllers like ODP going forward, we need to understand what’s happening in the commercial space. Let’s look at some well-known networking vendors and examine who has a controller today (or is planning to launch one):
This article has been updated now that Window Server 2012 R2 is generally available. Hyper-V Network Virtualization (HNV) is part of our Software Defined Networking (SDN) portfolio that is included inbox with Windows Server 2012 and Windows Server 2012 R2...
The ONF had been focusing on shepherding the OpenFlow standard and promoting the protocol’s use as a “substrate” for software-defined networking (SDN). But the idea of expanding its scope into northbound interfaces has been kicked around for a while.
Just how much work is ahead for network functions virtualization (NFV) became clear during sessions at last week’s Carrier Network Virtualization conference in Santa Clara, Calif. Presenters were bullish on NFV, but during the course of a day, they brought up several obstacles the technology still has to maneuver.
A discussion about white-box switches at the Carrier Network Virtualization conference included the usual talk about prices and opex as motivations for adopting white boxes — off-the-shelf switch hardware, also called bare-metal switching.
In this session, we illustrate how Equinixdelivers a unique and enhanced AWS Direct Connect global service offering thatenables secure, high-speed access with the flexible, dynamic bandwidth to meetthe needs of the evolving IT consumption trends.
Dell is revamping its campus access switches, phasing out the 10-year-old PowerConnect line in favor of the N series, which comes with a new operating system.
When it comes to API frameworks, there seems to be a Field-of-Dreams-esque view that If you build it, they will come. And as our industry dives headfirst into SDN waters, there will be people who advocate the proliferation of developer programs under the premise that networking needs an App Store.
