Design and Implementation of OSU Service Interface Model Based on ACTN/SDOTN

The design and extension of YANG interface model is a hot application area at present. In this paper, we give the design ideas of YANG interface model extension, and design the interface model of OSU service to meet the needs of new service launch based on ACTN/SDOTN. After development, practical application testing verification, the interface model can quickly expand OSU services function without affecting the existing online private line services of China U nicom.
