Hajder M. Methods and facilitiesincreasing effectiveness of designing distributed systems based on multichannels

This work is devoted to the problem of increasing effectiveness of designing, building and functioning of distributed computer systems and networks based on multichannels implemented in hardware. According to the experimental researches, the basic difficulties were found, which do not allow to provide high effectiveness of computer systems and networks of this class. Necessary definitions were formulated, topological virtualisation and topological hierarchy were characterized. The conceptual model of a distributed computer system with a topological hierarchy was proposed.Several estimation characteristics of a computer system with multichannels were proposed and practical results proved their selection. The special characteristics of multichannels computer systems life cycle were described. The algebra for finite undirected linked graphs were developed, which allows to describe topological links, with the aid of analysis of algebraic expressions. Physical topologies were analysed, the combinationof heuristic and genetic algorithms, the algebra of finite linked undirected graphs were proposed for building these topologies.
