Chuba I. The method of routing in heterogeneous computer networks on the basis of analysis hierarchies

The method of routing on a few criteria of quality of routes and method of evaluation of sensitiveness of decisions to declinations of initial data is defended. The mathematical models of computer networks, including models of processes of routing, are analyzed. Research of characteristic properties of routing tables which it is necessary to take into account at the choice of parameters of switching equipment and computer network structure is conducted. The recommendations are given in relation to the choice of different parameters of network (types of commutation nodes, logical topology of access networks etc.) depending on intensity of data flows, their temporal parameters and network structure. The function of sensitivity of decision of the choice of route to random perturbations of initial data is explored. It is shown that declinations of decision are the sizes of the second infinitesimal order in relation to the spectral radius of matrix of priorities.
