Software-defined Networking and Its Implementation By using Mininet

Abstract

Software Defined Networking (SDN) is an evolving networking technology concept that enables advancement about how to maintain and design network systems. Due to the separate data plane and control plane, consolidated management is assisted in a Software defined Network. In this thesis we did a compulsive study on SDN. Another important term is OpenFlow which is an SDN approach, presenting the inherent OpenFlow switches with such a centralized controller. OpenFlow switches are designed with flow tables that the controller can handle to use the OpenFlow protocol interface. An evaluation of an SDN emulation tool called Mininet is performed in this thesis. In Software Defined Networking (SDN) and OpenFlow, Mininet had been created to enable research. In this thesis we have used Mininet network emulator to create a virtual SDN network for OpenDaylight to control. A tree topology is created over OpenDaylight using mininet, which is a simple demonstration of SDN and understandable to everyone.
