SDN + cloud integrated control with statistical analysis and discrete event simulation

The software-defined infrastructure (SDI), which includes software defined networking (SDN), network function virtualization (NFV), and cloud computing, has the potential to provide the appropriate amount of resources dynamically to maintain SDI service, e.g., web IT service and video service. However, its operation requires expertness and know-how to manage complex configuration. In this paper, we propose an SDI service performance management system with statistical analysis and discrete event simulation. This approach maximizes service quality and simplifies the configuration simultaneously.
