Rethinking the WAN for an SDN future

In this video, John Burke of Nemertes Research considers how software-defined networking will affect the wide area network (WAN). He covers the key terms and concepts, the relationship between SDN and the WAN and specifically SDN apps for the WAN. SDN is the future of networking, Burke explains, but the technology is still in the "hype" phase, though it is "evolving rapidly."

Burke recommends that those running IT departments buy with SDN in mind, and look for OpenFlow-enabled products. Now is a good time to get educated and to build a test space. Ask carriers and ISP about their plans and, in next year, start thinking about how your branch stack would be replaced with SDN applications. In other words: Get prepared. But do you need SDN now? Several factors will determine the answer for your system.

Listen to Burke's presentation and you'll come away better informed on SDN's promise, what you need to do now and what your future SDN-enabled network might look like.
