The Evolution of Decentralized ICT Networks

Traditional networking systems, especially the famous 3 tier topology design, focused more on centralizing the networking systems, and used redundancy as a protection mechanism against future failures of the system. However, in recent years, the evolution of decentralization has taken place through several design techniques. Starting with clients requiring physically separate networks for critical applications. And then emerged the Spine Leaf topology and the Software Defined Network solutions. In this research paper, I will first, prove how decentralization is better than centralization using aspects of probability theory. Second, I will go further and show how the Spine Leaf and Software Defined Networks are inherently decentralized, redundant and are better than the traditional centralized networks.
