Abstract. Experiments on generation of applications flow in imitation models are carried out to deduce a combination of distribution laws for time intervals between applications correlated with real traffic in a computer networks. An imitation model of computer network is built in the Any Logic environment. The time of packet transmission in the channel is taken for a continuous random variable, and various laws of distribution of continuous random variable are used while configuring the model. Description of one of developed solutions for the traffic modernization is presented; based on proposed combination of the exponential, the uniform, and Weibull distribution laws, the deviation of the simulated flow from the real traffic is reduced from 40 to 6 %.
