Considerations on the Model Selection of SDOTN Controller Northbound Interface

Abstract

In the comprehensive digital transformation work, China Unicom takes the construction of SDOTN network as the top priority. This paper analyzes the reasons for the use of REST interface in SDOTN network. Based on the interface development experience, we make an in-depth interface model analysis of two mainstream northbound interface (NBI) of SDOTN controller, and give the basis and principles of model selection. Finally, the time to create the service is actually measured and the comparison data is given based on two different interface models.
