NS2 is a kind of network simulation software widely used in academic circles at present. It is often used in comput-er network course teaching. This paper introduces NS2 simulation network operation process and some of the commonly used analy-sis tools. It describes the working principle of Ethernet MAC layer protocol CSMA / CD. It explains Ethernet data transmission method and the factors of influencing performance by the simulation and analysis of trace file. These factors can be used for Ether-net protocol teaching in the computer network course.
