The document discusses SDN as a disruptive innovation and the role of open source and open communities in SDN and networking. It notes opportunities and challenges in leading the transformation to SDN. It examines how technology adoption cycles work and how network operators may consume SDN. It also discusses how incumbents may approach SDN in a way that preserves legacy systems rather than embracing disruption, and the impact disruptive innovation can have in high-tech industries. The keynotes at the summit will address these topics from Vinod Khosla and John Donovan from AT&T.
