Leveraging software-defined networking (SDN) to improve network scalability and flexibility

Abstract

Given their inflexible and unchanging characteristics, conventional network designs have difficulties with scalability and ease of adjustment. The ever-increasing size of networks creates an equally increasing complexity of managing data traffic and the resources required to do so. As a solution to these issues, Software-Defined Networking (SDN) has been developed which transforms network management by splitting the control plane from the data plane for centralized management and configuration of the network.This research studies the opportunity of employing SDN to improve flexibility and scalability in the context of large systems. Following the comprehensive analysis of networking basics and their problems, the study presents SDN architecture alongside its advantages and features. To assess the enhancements in performance concerning latency, throughput, and resource utilization, an experimental SDN framework is built and tested with simulation tools.Dynamic adaptation and more efficient scaling of resources becomes possible due to SDN integration, proving significant improvement of network performance. The study is concluded with recommendations for adoption of SDN in enterprise and cloud environments, pointing out the prospects provided by this solution for modern changes in networking approaches.
