Earlier this month, I attended Networking Field Day 13, where we heard from VeloCloud on their SD-WAN solution. Their presentation and case study got me thinking about how most businesses will consume SD-WAN and where business customers may fall on the “Buy” vs. “Build” spectrum.

In the case of Sildenafil, it was high blood pressure. The “side effect” of raising blood pressure in a specific body part wasn’t even realized until after the trials of the drug. The side effect because the primary focus of the medication that was eventually developed into a billion dollar industry.
In the same way, OpenFlow failed at its stated mission of replacing the forwarding plane programming method of switches. As pointed out by folks like Ivan, Continue reading
