Alternative methods of designing multi channel optical communication systems

This article attempts to discuss the problems in building new topologies utilizing a few alternative methods of designing systems like embedding, d-optimum topology. We propose to utilize Cartesian Product to describe graphs as a right mathematical solution to adjacency matrix. We propose methodology of building multi channel systems using a few original algorithms

Indeterminacy in the systems and networks design

As on the stage systems and networks operation, part of the parameters which are taken into consideration in the design process change its meaning, the project formed earlier can not satisfy the requirements. It is necessary to respect a variability at the time of selected system or network characteristics in the design process. The authors propose a method introducing an indeterminacy to the design process: design criteria, input parameters and model itself. It allows to obtain not one but a set of design solutions which specify given requirements and it is possible to take a human factor into consideration in the solution search process

Optical communication multibus systems

In this paper we present optical communication multibus system including: physical topology, logical topology, structure of central control unit (CCU). We describe the task of CCU: analyze the state of logical buses, topology reconfiguration, system structures clustering, unexpected events handling, statistic gathering, etc. In this paper we present synthesis of core system network basis on: MIN network, hypercube, ring topology and original embedding operation. We present logical structure of the systems including: logical interconnection buses, CCU, control transmission pattern, applicable logical topologies, reconfiguration methods, communication methods to connect autonomous multibus systems

Interconnection distributed systems designed with hierarchical organization

In this paper an origin approach to distributed systems design is shown. It allows to include complete costs of their life circuit. In order to simplify complexity of a design procedure we assume that a created system will have a regional hierarchical structure. A model based on the equivalence relation can describe that problem. In this way, it is possible to describe hierarchical regionalization simply for n-levels

Algorithmical and topological methods of fault tolerance assurance

Special interest in designing, constructing and exploitation of fault tolerant systems is connected with the need of attending to critical infrastructure systems. In this paper we focus on presentation and analysis of the requirements demanded on the context of fault tolerance assurance in the critical infrastructure systems. Especially, we take into consideration algorithmical and topological methods of fault tolerance assurance

A novel approach to fault tolerant multichannel networks designing problems

This work presents solution of a bus interconnection network set designing task on the base of a hypergraph model. In order to do this the interconnection network is presented as a multipartite hypergraph. A system with virtual bus connections functioning in an environment of common physical channel was analyzed, which is characteristic of the networks based on the WDM technology. The mathematical reliability model was proposed for two modes of system functioning: with redundancy of communication subsystem and division of communication load. As solution estimation criteria the expected changes of processing efficiency changes were used as also a communication delay change criteria and system reliability criteria. The designing task solution is searched in a Pareto set composed of Pareto optima. The selection procedure of a specific solution in the case of its equivalency in relation to a vector goal function was presented
