  Transport coefficients of gluon plasma are calculated for a SU(3) pure gauge
model by lattice QCD simulations on $16^3 \times 8$ and $24^3 \times 8$
lattices. Simulations are carried out at a slightly above the deconfinement
transition temperature $T_c$, where a new state of matter is currently being
pursued in RHIC experiments. Our results show that the ratio of the shear
viscosity to the entropy is less than one and the bulk viscosity is consistent
with zero in the region, $1.4 \leq T/T_c \leq 1.8 $.
