SDN Architecture Fundamentals & DOS Prevention Basics: A Case Study With Openflow

Abstract

The design of today’s network switching solutions goes back to the architecture designed in the 1970s. There is no significant change that took place despite IPv6 protocol. However, access speeds and the number of users are increasing continuously. There is a need for better network management and security. The Openflow protocol and Software Defined Network (SDN) architecture is a revolutionary change in network management and monitoring operations. In this study fundamentals of SDN architecture is given and a basic DoS detection and prevention system that can be performed with SDN is demonstrated.
