In a SDN-based data center network, the controller used greatly affects the behavior of the network. In this paper, the observation is conducted to describe the effect of various link failure scenarios to data center network performance using the Ripl-POX controller. Results shown in this paper can be used as a consideration for both controller selection or building for managing the data center and switch replacement method selection. This paper shows the effect of one to three switches that is turned down simultaneously on overall bandwidth. The simulation is done on 4k-fat tree data center network on mininet environment with RipL-POX as controller.
