Abstract: Methods, devices, and systems are disclosed for simulating a large, realistic computer network. Virtual actors statistically emulate the behaviors of humans using networked devices or responses and automatic functions of networked equipment, and their stochastic actions are queued in buffer pools by a behavioral engine. An abstract machine engine creates the minimal interfaces needed for each actor, and the interfaces then communicate persistently over a network with each other and real and virtual network resources to form realistic network traffic. The network can respond to outside stimuli, such as a network mapping application, by responding with false views of the network in order to spoof hackers, and the actors can respond by altering a software defined network upon which they operate.
