### Description

This talk is devoted to the study of $SU(3)$-gluodynamics bulk and shear viscosities temperature dependence. We measured the correlation functions of the Energy-Momentum Tensor for a set of temperatures in the region $T/T_c \in [0.9, 1.5]$. To extract the values of bulk and shear viscosities from correlation functions we applied various parametrical and non-parametrical approaches which give consistent results. Observed temperature dependence agrees with the recent experimental data. We notice a peak of bulk viscosity in the vicinity of phase transition, as for shear viscosity, there is a slight rise with the temperature at $T > T_c$. The analysis of our data confirms that the quark-gluon plasma behaves as a strongly-interacting system.
