The phenomenon known as "Internet ossification" describes the process through which certain components of the Internet’s older design have become immovable at the present time. This presents considerable challenges to the adoption of IPv6 and makes it hard to implement IP multicast services. For new applications such as data centers, cloud computing and virtualized networks, improved network availability, improved internal and external domain routing, and seamless user connectivity throughout the network are some of the advantages of Internet growth. To meet these needs, we've developed Software Defined Networking for the Future Internet (SDN). When compared to current networks, this new paradigm emphasizes control plane separation from network-forwarding components. To put it another way, this decoupling enables the installation of control plane software (such as Open Flow controller) on computer platforms that are substantially more powerful than traditional network equipment (such as switches/routers). This research describes Mininet’s routing techniques for a virtualized software-defined network. There are two obstacles to overcome when attempting to integrate SDN in an LTE/WiFi network. The first problem is that external network load monitoring tools must be used to measure QoS settings. Because of the increased demand for real-time load balancing methods, service providers cannot adopt QoS-based routing. In order to overcome these issues, this research suggests a router configuration method. Experiments have proved that the network coefficient matrix routing arrangement works, therefore it may provide an answer to the above-mentioned concerns. The Java-based SDN controller outperforms traditional routing systems by nine times on average highest sign to sound ratio. The study’s final finding suggests that the field’s future can be forecast. We must have a thorough understanding of this emerging paradigm to solve numerous difficulties, such as creating the Future Internet and dealing with its obliteration problem. In order to address these issues, we will first examine current technologies and a wide range of current and future SDN projects before delving into the most important issues in this field in depth.
