Description: The analysis of approaches and possibilities of mathematical design of modern telecommunication networks is conducted by the GERT-систем. The structure of process of transmission of metadatas is investigational in anti-virus systems. The mathematical model of technology of transmission of metadatas is developed in anti-virus nephystems on the basis of GERT-сети. Analytical expression is got for the calculation of closeness of distributing of time of transmission of metadatas in a network recognition real reliability and feature of the multiground routing indexes.
Keywords: anti-virus nephystems, ill-intentioned software, mathematical model, count, GERT-nets
