Comparison of software defined networking with traditional networking using NS2 simulator

Abstract

The Software Defined Network (SDN) is an emerging concept in network engineering that entails the decoupling of the control plane and data plane. The data plane is executed on discrete nodes, while a centralised control plane is accountable for overseeing network-wide functionalities. In conventional networks, the integrated planes are incorporated into the network suite, and the transmission is determined by the route. In this work, the traditional way of routing using a communication plane is compared with routing using an SDN controller. The present study employs the NS2 simulator to evaluate the quality of service performance under high background traffic conditions. In the event of network congestion, it is imperative to utilize the available bandwidth to its fullest extent in order to increase the rate of bit transmission per second. The results of the traditional network and SDN network based on various parameters like Ambiguous collision, Delay, Jitter, Availability and Latency are compared in this paper. The results show that the SDN network's performance is better with concerning time.
