Abstract. A method for estimation of functional reliability of computing systems is proposed. The method make use of probability of inquiry execution by the system in a time not exceeding the maximum permissible value. The estimation of functional reliability considers possibilities of adaptation to refusals and changes of inquiry stream as a result of redistribution of inquiries between computing knots through the network. Efficiency of inquiries redistribution through a network is demonstrated.
