NBI Modeling Realization for SDOTN Based on ACTN

The open Software Defined Network (SDN) capability of optical transmission network under telecom operation is always the core problem concerned by operators. Based on the idea of Abstraction and Control of TE Networks (ACTN), this paper analyzes the northbound interface (NBI) modeling of the controller system and explains how the interface model can meet the needs of the upper application system.
