Software Defined Networking technology is maturing and there are several real world use cases, but for most shops it is still a question of figuring out how we get there from here. In this Network World special report we analyze the promise and the options:
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.
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.
One gauge of industry progress on the software-defined networking front is the momentum of the Open Networking Foundation (ONF), the user-lead group that is spelling out the core SDN standards and championing the cause.
Software-defined networking (SDN) is the hottest thing going today, but there is considerable confusion surrounding everything from the definition of the term to the different architectures and technologies suppliers are putting forward.
One of the key challenges confronting potential users of software-defined networking is discerning the specific value of particular SDN controllers. Controllers, after all, play critical role as the key arbiter between network applications and network infrastructure.
If you aren't intimately familiar with software defined networking, don't fret. Only 10 per cent of 450 IT practitioners at a recent Network World event raised their hands when asked if they understand SDN. But if the emerging technology lives up to its promise to redefine networking as we know it, there is no time like the present to dig in and learn more.
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? Network World Editor in Chief John Dix put the question to Robert Sherwood, CTO of Big Switch Networks and head of the ONF's Architecture and Framework Working Group.
