The SDN vision took shape this year with vendors releasing products and roadmaps. Yet, the more vendors made moves, the more questions users had. Should they go with software overlays, or they should they hold out and re-architect their networks with controllers and new switches? Would there be some way to combine the two strategies? Would there be a hybrid approach?
SDN experts took to their blogs to discuss the new technology, but they also turned to Twitter to both share and seek information. In fact, Twitter seemed to create a whole new crop of SDN experts that suddenly had a healthy forum of listening ears. We picked 15 SDN experts that networking professionals should follow on Twitter.
