There are five computer network laboratories covering an area of about 405 square meters. The laboratory is mainly equipped with 160 high-performance computers, 9 groups of H3C routing and switching laboratory cabinets, about 65 other kinds of brand routers, about 20 switches, 75 firewalls, one information security training platform, and one network shooting range competition platform, the total assets of the experimental equipment are about 4.5 million yuan, including 1 set of cabling display, 4 sets of multimedia projection, 10 sets of air conditioning. The lab can provide basic experiments such as router/Switch/firewall configuration experiment, Static Route/dynamic route experiment, Router ACL Configuration Experiment, Network Protocol Analysis Experiment, Firewall filter experiment, etc. , the devices can also be connected in series via a central switch to meet the simulation requirements for large-scale topologies in real networks. The information security training platform is divided into three modules: Basic Information Security Training, Information Security Training and network attack and defense training. It contains more than 1000 experimental contents such as basic courses, cryptography, reverse engineering, and penetration testing, it can support up to 100 simultaneous online experiments. The Network Shooting Range Platform supports eight modes: basic theory, capture the flag and break through the barrier, host penetration, attack and defense confrontation, Evidence Tracing, enterprise environment penetration, security reinforcement and custom competition, covering the current international and domestic mainstream of the CTF events, while the platform can simulate building a variety of business scenarios, Real Enterprise Network and business scenarios simulation training, can support up to 75 people online competition. The integrated cabling display platform includes the classification display of wire and sensor, the overhead optical cabling model, the shaft cabling bridge model, the electrostatic floor cabling model, the metal pipeline cabling bridge model and so on. The computer network laboratory mainly completes the experimental and practical courses of Network Engineering, and provides the experimental environment for comprehensive cabling, network routing and switching, network attack and defense, Internet of things and so on. At present, the main courses are “network security” , “mathematical basis of information security” , “Network Security and attack and defense comprehensive practice” , “Network Protocol Analysis and design comprehensive practice” , “computer network” , “network management” , “network programming” , “wireless network technology” and so on.
