Method for implementing experimental system of firewall under multiple user's remote concurrency control in large scale

When user logs on system to start experiment, the method assigns the user an ID according to user ID allocation algorithm. When user starts up and shuts down own remote corresponding virtual machine, the method manages virtual machine system relevant to userí»s ID remotely according to virtual machine management algorithm. After user configures firewall rules, network command operation console embedded to WEB validates validity of firewall rules. Through network command proxy service program for remote user on firewall system, the network command operation console is connected to real network command operation terminal of virtual host to send out userí»s network command in real time, and display received result to user. The invention makes firewall system in multiple users provide experimentation for users so as to be applicable to practicing, training and popularizing technique of firewall.
