Advanced Study of Software-Defined Networking (SDN): Benefits, Recent Works, Challenges (Use Case for SDN-OpenFlow)

The Software Defined Networking (SDN) concept could be a means to deal with the demands and requirements of a rapidly increasing computer network infrastructure. Companies interested in expanding their network infrastructures are intrigued by the concept, but it's critical to consider the consequences of converting from a standard network to an SDN network. One strategy to mitigate the effects is to make a gradual transition from a traditional IP network to an SDN, resulting in a heterogeneous network. Rather than completely replacing the network infrastructure and dealing with the consequences, the soft migration concept is to replace a portion of it with an SDN environment and evaluate its performance. The efficiency of a network consisting of a traditional IP network mixed with SDN will be examined in this study. Identifying the variations in performance between having a heterogeneous network and having a specialized standard IP network is critical during this process. As a result, the problems addressed in this work will be how to construct such a heterogeneous network and how to quantify its performance in terms of throughput, latency, and packet drop. We hope to achieve our objectives with this study work by employing an experimental approach and analyzing relevant works on SDN fundamentals to provide us and the audience with a better understanding.
