Abstract
A method of computer simulation of a network device using its digital emulator and creating a digital environment for generating network traffic through it is presented. The emulated objects are represented by a set of functional and interface threads interacting through virtual communication lines, which are shared memory areas. This approach allows one to minimize the time spent on transferring packets between virtual devices of the emulated system and focus attention on the algorithmic component of the simulated device. As an illustration of the method, a computer simulation of the operation of a filtering device for the HTTP protocol as part of an information Web-system is demonstrated.
