MiniReal: A Real SDN Network Testbed Built over an SDN Bare Metal Commodity Switch

Abstract

In this paper, we design, implement, demonstrate the functions, and evaluate the performance of MiniReal - a real SDN network testbed built over an SDN hare metal commodity switch. Using MiniReal, one can partition an SDN hare metal commodity switch into several SDN slice switches and use Ethernet cables or optical fibers to connect these slice switches together to form any desired network topology. It is very quick and easy to change the formed network topology from one topology to another topology. Once the initial wiring is done, our software can change the network topology in less than 1 second without physically rewiring any cable between slice switches.
