Abstract: This demo paper presents EConVi, a framework to support the implementation and visualization of the energy efficient software defined networking (SDN). This framework monitors the network workload, and dynamically changes the operational states of the switches and routing paths of flows, based on the controlling algorithms. The network topology, traffic workloads on each network link and switch, and the operational states of the switches are visualized. EConVi is able to manage the large-scaled networks simulated in the SDN emulators such as Mininet, or interact with DVFS-enabled hardware nodes installed with software switches, as shown in our demo.
