FIELD: information technologies. ^ SUBSTANCE: alternative routes of message packets are extracted from topological circuit of data-computing network and memorised for each pair of alternative connections to data-computing networks of subscribers. Value of complex index of safety IKi of i unit of data-computing network, where i=1, 2, 3,Ç, is compared with previously specified minimum permissible value of Imin. Following comparison results, unit is memorised as "dangerous" or "safe". Critical ratio of "dangerous" and "safe" units pjÇèk is calculated for each j version of subscribers connection, at which adjacent "dangerous" units form circuits that exclude exchange between subscribers. For this purpose, pj part of units is chosen randomly from each previously memorised version of subscribers connection out of their total number, and those are memorised as "dangerous". Joint circuits are formed from adjacent "dangerous" units, and they are memorised, share of "dangerous" units is increased serially by value öp, and formation of joint circuit is repeated until condition pj= pjÇèk is met. Alternative options of data-computing network subscribers connection are ranged by pjÇèk value, and an option with maximum pjÇèk value is selected from them. ^ EFFECT: improved validity of results of comparative assessment of data-computing structures in case of communication units quantity increase and under conditions of effect at communication channels, and units of data-computing network for accidental and deliberate noise. ^ 11 dwg |
