Intelligent OAM of New Generation Access Network Based on SDN

With the rapid development of the optical access network and the trend of full service access bearer, the operation, administration, and maintenance (OAM) of the optical access network also face more and more challenges. This paper analyzes the limitations of the traditional access network OAM interface, introduces the key enable technologies in access network to implement agile, automated and intelligent OAM. It provides application scenario for intelligent OAM and supports passive OAM. The evolution from OAM to active OAM effectively improves the intelligent OAM capabilities of the optical access network, thereby helping network operators to cope with various challenges in OAM of new services, enhancing service operation capabilities, and improving the end user's business experience.
