Software-Defined Networking (SDN) is a new approach to networking that realizes network programmability and dynamic control over the network. OpenFlow is a de facto standard protocol used to implement an SDN. However, understanding the dynamic behavior of an OpenFlow network is challenging since the information about the operation is distributed across numerous network switches. This thesis presents a tool called Opimon (OpenFlow Interactive Monitoring) that monitors and visualizes an OpenFlow network. Opimon is capable of monitoring and visualizing the network topology and flow tables of switches in real-time. Furthermore, it analyzes network traffic to detect DDoS attacks. A web-based user interface enables users to quickly understand network behavior and identify problems. Opimon has been successfully deployed on PRAGMA-ENT, an international network testbed, and utilized by researchers to study the behavior of the testbed.
