Transport Software Defined Networking: Grabbing the Low-Hanging Fruit


This report is the first of a two-part series that examines the fundamentals of SDN and describes the emerging role of Transport SDN, and then, in the second installment, compares the key vendor approaches as they stand today. This first installment examines the reasons why service providers are considering SDN for their networks and presents some of the challenges to deploying SDN in service provider networks. It defines a relatively new variant of SDN, Transport SDN, and describes how it can be used to overcome some traditional service provider challenges. Finally, the report looks at a particular Transport SDN challenge – multi-vendor interoperability - and a potential solution to the challenge – Open Transport Switching (OTS).
