Analyzing Core Concepts of Communication Technologies in Traditional and SDN Networks

Abstract

This thesis explores the foundational concepts of traditional computer networks and introduces the transformative role of Software-Defined Networking (SDN) in modern communication systems. The work begins by laying out the essential elements of traditional networking, including routing, switching, and network segmentation, before shifting focus to the architecture and logic behind SDN. To bridge theory and practice, a set of hands-on labs was developed using Cisco Packet Tracer, allowing for a step-by-step exploration of real-world network scenarios. These labs simulate both traditional and SDN-based setups, offering practical insights into how network behavior changes when central controls are introduced through SDN controller. The thesis aims not only to clarify technical concepts but also to illustrate the benefits of adopting SDN. By comparing traditional configurations with those enhanced by SDN controllers, it becomes evident how centralized management, flexibility can lead to more efficient and scalable network operations.This thesis explores the foundational concepts of traditional computer networks and introduces the transformative role of Software-Defined Networking (SDN) in modern communication systems.
