The Computer Network Laboratory of Computer Science department in Tsinghua University provides experimental environment for undergraduate computer network serial courses offered by CS Dept. In order to meet the demand of different elective students, we combed experimental teaching system of computer network serial courses, then designed and implemented a remote network laboratory supported multi-level network practice. We mainly deployed three series of experimental system: Virtual Network Experiment System based on commercial network equipment, Network Protocols Experiment System named NetRiver and IPv4/IPv6 Transition Technologies Experiment System based on 4over6 tunneling technology. With the help of our network laboratory, the following goals can be achieved: 1) Remote. Students can access experimental environment from classroom, dormitory and etc.; 2) Multi-level. Experimental contents include both network principle and commercial realization, include both classical sliding window protocol, IPv4 or IPv6 data transceiver protocol, IPv4 or IPv6 data forwarding protocol, routing protocol and up-to-date IPv4/IPv6 Transition Technologies. Every network course can construct experimental content by combination of them; 3) Up-to-date. We introduced the latest technology in the field of computer network research, such as IPv6 network protocol and 4over6 tunneling technologies.
