Samuel N. Increasing the efficiency of data exchange in computer networks based on the protocol of TCP/IP suite

Research object - the computing environments, the local and corporate networks scale, that functions based on the protocols of TCP/IP suite. The aim of this research is to increase the efficiency of data exchange in modern network applications and computer networks environments based on the protocol of TCP/IP suite. Methods of research - was using the theory of computer networks and networks of mass service, theory of probability and methods of statistical evaluation of imitational designs, and model experiment. Scientific novelty - developed special simulation complex models for analyzing many-levels model of processes data exchange in a computer networks. Dependences are achieved, that characterize the conformities law of changes the real bandwidth capacity during realization of different modes of data exchange in the local and corporate networks scale and allowing during a given condition of network to execute quantitative comparison of different modes of data exchange with the target to choice themost rational from them. A method is offered to increase the efficiency of network data exchange based on the use of complex simulation models. Models and tools of research and development of network structures were developed used by the computer company "Sintal" in projecting and service of computer networks, during exploitation of corporate network DonNTU, and also - in an educational process at the department of electronic computing machines Donetsk national technical university during conducting classes on the discipline "Network information technologies". An area of application is a computing engineering.
