Firstly, several software defined network (SDN) architectures and their key technologies were introduced.Secondly, technical research on the applicability of these SDN architectures in optical transport network (OTN) on several key aspects such as network layering and network abstraction, southbound interface protocol selection, and path computation element (PCE) function integration was conductd and analyzed.Finally, guiding opinions and suggestions on the migration of the existing OTN network to these SDN technical architectures were given.

Key words: OTN, SDN, applicability
