Development and Software Implementation of Computer Network Algorithm

Abstract

In this paper, we consider the problem of modeling computer networks. The description of the basics of computer modeling is given. We have demonstrated the development of the structure of the program. Information model of the computer network is shown, a detailed description of its components is given. The algorithm of the constructed model is given. A generic algorithm for implementation of transfer processes messages in the simulation model on the basis of constructed and marked out a joint venture is shown. The structure of the program is demonstrated. The developed environment for simulation of computer networks allows us to study in detail the processes that occur in computer networks during their creation and subsequent operation. To build models in this environment, the presence of related groups of objects representing certain elements of a real network is provided. The simulation of infor-mation exchange processes between model objects is carried out by sequential processing of events, each of which reflects the manifestation of certain processes in the elements of the network under study. The main windows of the software product interface are described. When choosing the right type of equipment in the right drop-down list on the left displays all the devices of the selected category. When you select a device from the left drop-down list it will be an icon of the device. We can combine these virtual devices into a fully fledged network routers, workstations, servers and others. The device can change or display its properties. In the properties window the information can be seen about the device, its parameters and characteristics. Each device we can set according to four points of network activity. During simulation of computer network, the user can do real-time monitoring of network activity. The results can be widely used for modeling various classes of computer networks.
