  Numerical results for the transport coefficients of quark gluon plasma are
obtained by lattice simulations on on $16^3 \times 8$ lattice with the quench
approximation where we apply the gauge action proposed by Iwasaki. The bulk
viscosity is consistent with zero, and the shear viscosity is slightly smaller
than the typical hadron masses. They are not far from the simple extrapolation
on the figure of perturbative calculation in high temperature limit down to $T
\sim T_{c}$. The gluon propagator in the confined and deconfined phases are
also discussed.
