Performance Analysis of Various SDN Controllers in Mininet Emulator

Abstract

The exponential increase in the number of internet users, managing the network flow becomes a difficult task for network administrators. These limitations are overcome by using Software Defined Networking (SDN). SDN separates the control plane and data plane hence it provides the control from centralized controller to the network. Thus it offers flexible and inexpensive solutions to the limitations of the network. This paper aims to give a comparison of performances analysis of various SDN controllers like Ryu, OpenDayLight, Floodlight and ONOS controllers. To compare the performances of these controllers two QoS parameters are considered they are average delay and throughput. Performances of these controllers are analyzed for three different network topologies for different number of connections. Network topologies considered are linear, tree and mesh topologies. So the performance analysis of these controllers gives an idea of selecting a better performing controller for implementation of different application for the network.
