Southbound API modules enable services like interconnectivity and interoperability between network and controller. It controls over dynamic changes in network behavior with real time demands and responses. Advance infrastructure module is responsible for providing functional services. These services are controlling the degree of connectivity between various nodes and functioning among them, selection of optimal path for a data packet among various paths from source to destination. Metric standard for determining optimization level may be differing from level to level of network infrastructure. Network applications can be treated as various programs which work combined with network architecture and provide core group of services like network slicing. North-bound API's control interaction level between external services and controller. MACHINE LEARNING AND SDN We are conducting research on methods to solve network management and operation problems using machine learning and data analytics. Machine learning can extract latent rules and generation models of network behavior through big data analytics, and those rules and models can be used for predicting and optimizing network management and operation, which improves network service and reduces costs. In this article, we introduce methods to predict and detect network failures using a social networking service (SNS) or network logs, extract workflows from operator logs, and predict mobile traffic from traffic generation factors. To minimize the impact on services caused by a network failure, we must detect a failure or a fault that leads to a failure, before it occurs or as soon as possible after it occurs.
