Abstract
Today, simulation is the main tool that allows to evaluate the effectiveness of software and hardware solutions (data routing protocols, mechanisms of access to the transmission medium, transmitting devices) developed for multi-step wireless networks. However, the lack of a unified testing methodology for multi-step wireless networks does not allow comparison of the solutions proposed by the developers based on simulation models that reproduce the same conditions for all the functioning of these networks, implying the same values of parameters and scenarios. Currently, local area networks (LAN) are widely used in various fields of human activity. In the process of LAN development there was a standardization of technology of combining computers into a network-Ethernet, FDDI, Token Ring, etc. the most widespread was the Ethernet network, the architecture of which is determined by the IEEE 802.3 standard and is based on the Protocol of functioning of the common CSMA/CD transmission medium. Currently, both in Russia and abroad, almost the only approach to solving the problem of choosing a LAN topology is the experience of system integration engineers. Since LAN are very complex systems, it often leads to the adoption of suboptimal decisions in their design. The only way to avoid these difficulties is to make a decision using computer-aided design. This article describes the simulation modeling of networks operating on the IEEE 802.3 Protocol family. The peculiarities of simulation of networks operating according to protocols IEEE 802.3, disadvantages, advantages.
Keywords: simulation modeling, router protocols, IEEE 802.3, testing tools, bandwidth.
