Abstract

Software Defined Network (SDN) decouples networks control plane and data plane, make the controller gain the global network topology view which can be utilized by the controller’s forwarding applications to forwards the packets between hosts with the helping of openflow protocol. The POX controller and Mininet tool has been used to simulate the underlying SDN infrastructure. This paper analyze a different data forwarding components currently supported by the POX controller, where three components are compared, hub, l2_learning, and l2_multi, by measures the Round Trip Time (RTT) and CPU usage.
