Atlantic Security Conference

Software Defined Network (SDN) is a new approach of designing networks. In SDN architecture network control function is decoupled from hardware like routers and switches. This decoupled control function is executed in a logically centralized controller with a global network view. Furthermore, SDN brings network programmability. The decoupled control plane, global network view and network programmability bring efficiency and flexibility in network management and configuration. This talk will introduce Software Defined Networking. The controller is considered as a cornerstone in SDN based design. Thus, there will be a performance comparison of two important SDN controllers ONOS and OpenDaylight. Finally, the talk will provide an overview on the benefits and weaknesses of SDN based design in the context of network security.
