    Summary:We found by some computer experiments that the method of packet routing control using a neural network ,which was proposed by Horiguchi and Ishioka [1], was not so effective when it was applied to computer networks with some kinds of topology. In the present report, to overcome this problem, we propose a modified method of the packet routing control with stochastic effects and confirm its effectiveness by some computer simulations.
