Performance analysis of POX, open vswitch and open day light SDN controllers on cloud

Abstract

Software Defined Networking (SDN), as a revolutionary technology is changing the way traditional computer networks used to function. It is a replacement of traditional networks where control of the network was embedded with the data layer. Software Defined Networks separates control layer from data layer which enables network administrators to reconfigure the network easily without making any physical change in the network. An SDN network has various components like switch, controllers and hosts. Generally, SDN controllers are considered the “brain” of this network. In this paper, firstly, performances of three SDN controllers POX, Open vSwitch (OVS) and OpenDayLight (ODL) are analyzed for single topology on cloud on the basis of three parameters Round-Trip-Time, Average Time and Total Time. Results show that OVS controller outperforms POX and ODL controllers. Later, the performance of these three controllers has also been analyzed for different topologies on local machines.
