Comparative performance analysis of SDN vs traditional networks using SDN controller

Abstract

New difficulties have been presented to the future of the Internet by emerging devel opments in information and communication technology (ICT) and numerous Inter net services, with high priority given to dynamic maintenance and high bandwidth. Considering traditional networking techniques, where device setups are conducted manually and the network infrastructure’s capacity is not completely exploited, the high bandwidth required for transmitting enormous amounts of data cannot be at tained. SDN, or software defined networking, is a new approach to solving these issues. This study compares and contrasts the performance of conventional networks versus SDN. By contrasting round-trip propagation latency between end nodes and maximum attainable throughput between nodes in traditional as well as Software defined network environments, a performance study for fundamental and suggested network topologies is conducted using simulations carried out in Mininet.
