Enterprise infrastructure company Infoblox announced this week that it plans to release a free and open-source software tool called Tapestry aimed at generating a hard measurement of any network's complexity.
Software Defined Networks should makeĀ IT execs think about a lot of key factors before implementation.
In our first Network World Spotlight, "Understanding SDN" we spelled out the basics. Here we catch you up on the status of the movement and begin to lay out how you get there from here, examining basic planning, what to look for in an SDN controller, and discussing what the Open Networking Foundation hopes to achieve with its new Migration Group.
Juniper Networks is now shipping its SDN controller and has also made it available as open source code, signaling an intention to not develop product around the OpenDaylight SDN consortium's work.
Understand how SDN will change everything in 10 easy steps
NetSocket this week shifted gears from monitoring the
quality of unified communications applications to enabling software defined
networks, with an initial focus on automating tuning in order to accommodate business
performance policies.
When getting to know software defined networking, you'll encounter a number of terms that are used in conjunction with the technology. Some of the terms are unique to SDN, while others describe technologies that, while not unique, are frequently used in SDN designs.
Software has been programming our networks for a long time, so how is SDN different?
Software defined networking (SDN) offers significant opportunities and challenges for enterprise IT professionals. SDN has the potential to make networks more flexible, reduce the time to provision the network, improve quality of service, reduce operational costs and make networks more secure.
In today's data center you need to be able to add services and hardware without compromising network performance, but the flexibility to tune the network to meet business needs is also mandatory.
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.
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.
Public cloud and managed hosting provider Rackspace has rolled technology from Vyatta into its services, allowing customers to set granulated network segmentation policies that dictate which users and what type of traffic have access to which hosted resources.
Software defined networking was a hot topic at the recent Interop conference in Las Vegas, where enthusiasm for the emerging technology overpowered any lingering doubts.
