The mathematical model of Front-End calculating in DPI system

This article describes the specialized servers in the architecture of the DPI system. The paper discusses the mathematical model for calculating Front-End server in DPI system, based on the Wentcel-Ovcharov model. In particular, the possibility of practical application this mathematical model for calculating the remaining servers in the DPI system, showing the improved model of WenzelOvcharov. It describes the created simulation model of DPI in GPSS World. Finally, it compares the results of mathematical and simulation modeling.
