Subjects of research: associative switching system structure, associative switching system networks, associative switching and routing, their models and design methods Purpose of work: research and design of switching node models and designing methods of the broadband multilevel N-dimension associative switching networks. Methods of research: researches based on algebraic system of associative switching, probability theory, queueing theory, group theory, z-transform methods, matrix algorithms, parametric analysis of time-probabilistic characteristics and network stricture optimization. The results obtained and their novelty: associative switching fabric model based on group theory with alphabet A and substitution system F; switching task solution in the network modules of the associative switching system is represented as multiplication operation of multiplicative algebraic substitution group of matrix elements in RAM and program memory (function domain of Neighbourhood Single Radius NSR); analytical models of associative switching system of the ring and star structures. Practical value: Formulas for practical design of associative switching system arc obtained. Formulas allow to choosing associative switching system parameters according specified requirements and initial data. It’s defined associative switching fabric application in switching systems have more higher performance in comparison with traditional switching systems. Degree of embed and economic cffcctivity: results have been implemented to JSC “Uzbektelecom” and into educational program of Tashkent university of information technologies TU1T. Field of application: dimension, design, realization of associative routing and switching mechanism for access and transport telecommunication networks.
