Performance Comparison of the Proposed OpenFlow Network with the Pox Controller and the Traditional Network in Software Defined Networks (SDN)

Abstract

The dynamic structure of today's networking system, in which the control plane is fully dispersed throughout the network and networking equipment (e.g., switches, routers) have their own local control-plane and data-plane, makes networking system management more complicated. Networking paradigm that can be programmed by separating the management function from the networking elements and putting it in a logically centralised control plane, SDN makes it simple to administer and operate this dynamic networking system. The forwarding devices are made easier by the separation of the control and data planes. A logically centralised control-plane is in charge of the control, management, and configuration of these simple forwarding devices.. SDN's control plane is frequently referred to as the network operating system. The purpose of this dissertation is to evaluate the performance of an OpenFlow enabled software defined network model with a POX controller to that of a traditional network. Mininet is a tool that is used to design and analyse traditional and programmable networks. Latency, throughput, packet loss, and jitter characteristics are used to evaluate performance.
