Abstract

With the explosive growth of network applications and traffic, SDN architecture has become one of the key technologies of future networks. However, currently, most computer network laboratories in higher vocational colleges do not support relevant experiments on SDN networks, which is not conducive to the systematic learning of the architecture, configuration and application of SDN networks for students majoring in computer networks. Based on the key technologies of SDN and the existing experimental environment, a transformation scheme for computer network experiments that supports SDN is proposed to solve the simulation problems of controllers, OpenFlow switches and virtual hosts in SDN networks. In this laboratory environment, a comparative experiment on building SDN networks with using Mininet and a joint flow table experiment with Ryu and Mininet are carried out.

Keywords

SDN; computer network laboratory; Ryu Controller
