Network operators are deploying Software Defined Networks (SDN) to enable programmability of their networks for efficiency, speed of deployment and new revenue-generating network services.  Widespread adoption of the programmability paradigm depends on the availability of common or standardized APIs that allow access to domain specific attributes and mechanisms without requiring the API itself to be specific to the vendor or technology. The Transport API (T-API) is designed to allow network operators to deploy SDN across a multi-domain, multi-vendor transport infrastructure, extending programmability across their networks end-to-end.

By working through the specifications, rigorous interoperability testing and validation, OIF has substantiated T-API as the Northbound Interface (NBI) of choice. OIF, in collaboration with industry leaders, has helped establish a foundation for open, programmable networks that allow operators to efficiently deliver dynamic multi-domain connectivity services to the market.
