Unveiling the Landscape of Network Architectures: A Deep Dive and Multi-Criteria Analysis of SDN and Traditional Networks

The advancement of computer networks has resulted in the emergence of various networking architectures, including Software-Defined Networking (SDN) and traditional networks. While traditional networks use a distributed approach, SDN uses a central system that makes network management and control more efficient. This paper aims to compare SDN and Traditional Networks in detail, looking at how they’re built, how well they perform, and how they’re managed. We also look at the pros and cons of each architecture, summarized in a SWOT analysis. Additionally, the paper uses a Multi-Criteria Analysis to further compare SDN and Traditional Networks on important factors like control, scalability, flexibility, and security. Overall, this paper provides useful insights into the differences between SDN and Traditional Networks, emphasizing the benefits of choosing SDN and paving the way for solving problems with SDN in the future.
