Software-defined networking: Reconfigurable network systems in LAN topology

An emerging technology of SDN plays a vital role in network reconfiguration. In an existing system, real word experiment on dynamic changing network topology lacks the ability to change the network configuration. The article works for dynamic reconfiguration in networking through high-level programmability via such C++ or python via SDN controller. In this paper, SDN enable an innovation performance for improving the network reconfigurability through three resources such as controller (Raspberry pi), switch and host nodes. The protocol of Openflow acts as an interface between controller and switch. As a result, the dynamic network reconfigurability solves the problem of manual configuration and reconfiguration to the network operator where the system deploys on campus network.
