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.
