In accordance with priority guidelines of information technologies development it is important to create a unique informational field which will connect state authorities, ministries and departments. At the same time while forming such a difficult informational and telecommunicational system, the problem of its stable functioning under the possible destructive impact emerges. Unpredictability of most effecting factors, which influence the qualities and topology of the system, gives special importance to analysis of its functional vitality taking into account the condition of the system elements and their actual connections. The article represents the model, which takes into account resource and temporal characteristics of dispersed calculation process into the informational and telecommunicational system, which is under the destructive impact. The received analytical correlations allow to estimate the temporal losses during the information processing under the condition of non-accidental degradation of calculation system while realization different ways of loading reserve computing modules.
