Abstract

Software Defined Network(SDN)is a new type of networking paradigm with the characteristics of centralized control and network programmability,which provides a definable network platform for application innovation.In order to carry out the cyberspace security course experiment in a quick and convenient way,a network security classic experiment teaching program which was based on SDN architecture is designed and implemented with Mininet as the light-weighted experimental platform.The test program is combined with Python language programming and the simple command line operation of Linux,designed the classic experimental teaching scheme of network space security.Taking the Border Gateway Protocol(BGP)path carrying and Address Resolution Protocol(ARP)attack and defense experiment as experiment an example,the new network innovation architecture Software Defined Network(SDN)is introduced and the network topology configuration,routing configuration and user interaction process of the experimental platform are displayed.This experiment helps to enhance students' understanding of cyberspace security and cultivate students' innovative consciousness and practical ability.
