Network Augmentation by Dynamically Splitting the Switching Function in SDN

Software-defined networking is a synonym for the term programmable network and is the Key for 5G and beyond networking paradigms. Software-defined network (SDN) provides network management and controlling features irrespective of the hardware configurations and network infrastructure. Network slicing is the process of separation of multiple virtual networks based on different functions or tasks such that one application does not interfere with another network. Network slicing allows separating the control plane from the user's plane. Various investigators have investigated how the slices that have been used for splitting paths can be measured to improve durability. In SDN, the dynamic migration of switches offers a method of offloading the load from one controller to another controller. We have reintroduced the concept of the network (dataflow) splitting for load balancing in SDN. In this paper, we compare the performance techniques and found that the splitting paradigm with dynamic migration offers the most balanced network flow and least overhead on the SDN controller.
