What are your predictions for the SD-WAN market in 2016?

SD-WAN will go mainstream in 2016. We'll see more companies leveraging SD-WAN technology to bring their idle links to life, adding broadband Internet as part of a hybrid MPLS-Internet WAN, or even ditching MPLS and implementing dual broadband connections to the branch.

We'll also see … the emergence of new branch-office architectures. Instead of deploying an expensive integrated services router as a Swiss army knife, I think enterprises (will prefer) two new alternatives: the thin branch and the converged branch. Services are becoming more centralized and regionalized, so the traditional networking footprint in small-to-medium branches can be replaced with a simple SD-WAN edge device. For larger branches, we'll start to see increased adoption of hyper-converged infrastructure solutions.
