A Study of Performance Evaluators for Software Defined Networking

Software Defined Networking is a novel paradigm for researchers. This field has sub-domains with different issues which need to be worked on and provide solutions, as in other fields of research. Simulation is one of the most commonly used methods by researchers to study and evaluate new theories as well as the behavior of any existing network. In this paper, an attempt has been made to provide a comprehensive study and analysis of different open source simulators and emulators freely available for Software Defined Networks. Various merits have been discussed along with limitation they possess in simulating the Software Defined Networks. The goal is to introduce newbie to different software available for evaluating the network for the purpose of research in this emerging field. Selection of a network simulator is a crucial task for researchers. This article provides help to the scholars to choose the software that suits their requirement of performance evaluation in the area. The idea is to compare these performance evaluators by first simulating a topology and then some specific parameters, to find the optimal one.
