This presentation talks about the role of SDN in driving innovation, agility and efficiency in the transport network. It covers a few use cases where this SDN capability in the IP/Optical domain can be combined with some already well talked about applications of SDN in Virtualization of Network Functions, Service Chaining and Enterprise IT services

SDN applications are maturing in contained domains
Services are created and consumed holistically
Transport SDN is a piece of the puzzle that needs to be
in place
